Either of a pair of compound bones forming the lateral (left and right) surfaces and base of the skull which contains the organs of hearing. It is a large bone formed by the fusion of parts: the squamous (the flattened anterior-superior part), the tympanic (the curved anterior-inferior part), the mastoid (the irregular posterior portion), and the petrous (the part at the base of the skull).
Bone and Bones
The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.
Round Window, Ear
The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.
Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.
The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (COCHLEA; VESTIBULAR LABYRINTH; and SEMICIRCULAR CANALS) in the TEMPORAL BONE. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (COCHLEAR DUCT; SACCULE AND UTRICLE; and SEMICIRCULAR DUCTS) forming a continuous space enclosed by EPITHELIUM and connective tissue. These spaces are filled with LABYRINTHINE FLUIDS of various compositions.
Cerebrospinal Fluid Otorrhea
Discharge of cerebrospinal fluid through the external auditory meatus or through the eustachian tube into the nasopharynx. This is usually associated with CRANIOCEREBRAL TRAUMA (e.g., SKULL FRACTURE involving the TEMPORAL BONE;), NEUROSURGICAL PROCEDURES; or other conditions, but may rarely occur spontaneously. (From Am J Otol 1995 Nov;16(6):765-71)
Cholesteatoma, Middle Ear
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
A usually benign tumor composed of cells which arise from chondroblasts or their precursors and which tend to differentiate into cartilage cells. It occurs primarily in the epiphyses of adolescents. It is relatively rare and represents less than 2% of all primary bone tumors. The peak incidence is in the second decade of life; it is about twice as common in males as in females. (From Dorland, 27th ed; Holland et al., Cancer Medicine, 3d ed, p1846)
Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).
Three long canals (anterior, posterior, and lateral) of the bony labyrinth. They are set at right angles to each other and are situated posterosuperior to the vestibule of the bony labyrinth (VESTIBULAR LABYRINTH). The semicircular canals have five openings into the vestibule with one shared by the anterior and the posterior canals. Within the canals are the SEMICIRCULAR DUCTS.
Bone Marrow Cells
Severe or complete loss of facial muscle motor function. This condition may result from central or peripheral lesions. Damage to CNS motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. FACIAL NERVE DISEASES generally results in generalized hemifacial weakness. NEUROMUSCULAR JUNCTION DISEASES and MUSCULAR DISEASES may also cause facial paralysis or paresis.
Tomography, X-Ray Computed
The 7th cranial nerve. The facial nerve has two parts, the larger motor root which may be called the facial nerve proper, and the smaller intermediate or sensory root. Together they provide efferent innervation to the muscles of facial expression and to the lacrimal and SALIVARY GLANDS, and convey afferent information for TASTE from the anterior two-thirds of the TONGUE and for TOUCH from the EXTERNAL EAR.
Hearing Loss, Conductive
Hearing Loss, Sensorineural
Facial Nerve Diseases
Diseases of the facial nerve or nuclei. Pontine disorders may affect the facial nuclei or nerve fascicle. The nerve may be involved intracranially, along its course through the petrous portion of the temporal bone, or along its extracranial course. Clinical manifestations include facial muscle weakness, loss of taste from the anterior tongue, hyperacusis, and decreased lacrimation.
Oval Window, Ear
Hearing Loss, Mixed Conductive-Sensorineural
Large endothelium-lined venous channels situated between the two layers of DURA MATER, the endosteal and the meningeal layers. They are devoid of valves and are parts of the venous system of dura mater. Major cranial sinuses include a postero-superior group (such as superior sagittal, inferior sagittal, straight, transverse, and occipital) and an antero-inferior group (such as cavernous, petrosal, and basilar plexus).
Electronic hearing devices typically used for patients with normal outer and middle ear function, but defective inner ear function. In the COCHLEA, the hair cells (HAIR CELLS, VESTIBULAR) may be absent or damaged but there are residual nerve fibers. The device electrically stimulates the COCHLEAR NERVE to create sound sensation.

Otorhinolaryngologic Surgical Procedures
Spiral Ligament of Cochlea
A nonspecific symptom of hearing disorder characterized by the sensation of buzzing, ringing, clicking, pulsations, and other noises in the ear. Objective tinnitus refers to noises generated from within the ear or adjacent structures that can be heard by other individuals. The term subjective tinnitus is used when the sound is audible only to the affected individual. Tinnitus may occur as a manifestation of COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; and other conditions.
Synthetic or natural materials for the replacement of bones or bone tissue. They include hard tissue replacement polymers, natural coral, hydroxyapatite, beta-tricalcium phosphate, and various other biomaterials. The bone substitutes as inert materials can be incorporated into surrounding tissue or gradually replaced by original tissue.
Hearing Loss, Sudden
An illusion of movement, either of the external world revolving around the individual or of the individual revolving in space. Vertigo may be associated with disorders of the inner ear (EAR, INNER); VESTIBULAR NERVE; BRAINSTEM; or CEREBRAL CORTEX. Lesions in the TEMPORAL LOBE and PARIETAL LOBE may be associated with FOCAL SEIZURES that may feature vertigo as an ictal manifestation. (From Adams et al., Principles of Neurology, 6th ed, pp300-1)
An oval, bony chamber of the inner ear, part of the bony labyrinth. It is continuous with bony COCHLEA anteriorly, and SEMICIRCULAR CANALS posteriorly. The vestibule contains two communicating sacs (utricle and saccule) of the balancing apparatus. The oval window on its lateral wall is occupied by the base of the STAPES of the MIDDLE EAR.
Spontaneous CSF otorrhea caused by abnormal development of the facial nerve canal. (1/406)In two patients with surgically proved CSF fistula through the facial nerve canal, MR and CT examinations showed smooth enlargement of the geniculate fossa with CSF signal. In the clinical setting of CSF otorrhea or rhinorrhea, the presence of an enlarged labyrinthine facial nerve canal and enlarged geniculate fossa on CT scans and CSF intensity on MR images strongly suggests a CSF fistula through the facial nerve canal.

Evaluation of CSF leaks: high-resolution CT compared with contrast-enhanced CT and radionuclide cisternography. (2/406)BACKGROUND AND PURPOSE: Radiologic evaluation of CSF leaks is a diagnostic challenge that often involves multiple imaging studies with the associated expense and patient discomfort. We evaluated the use of screening noncontrast high-resolution CT in identifying the presence and site of CSF rhinorrhea and otorrhea and compared it with contrast-enhanced CT cisternography and radionuclide cisternography. METHODS: We retrospectively reviewed the imaging studies and medical records of all patients who were evaluated for CSF leak during a 7-year period. Forty-two patients with rhinorrhea and/or otorrhea underwent high-resolution CT of the face or temporal bone and then had CT cisternography and radionuclide cisternography via lumbar puncture. The results of the three studies were compared and correlated with the surgical findings in 21 patients. RESULTS: High-resolution CT showed bone defects in 30 of 42 patients (71%) with CSF leak. High-resolution, radionuclide cisternography and CT cisternography did not show bone defects or CSF leak for 12 patients (29%) who had clinical evidence of CSF leak. Among the 30 patients with bone defects, 20 (66%) had positive results of their radionuclide cisternography and/or CT cisternography. For the 21 patients who underwent surgical exploration and repair, intraoperative findings correlated with the defects revealed by high-resolution CT in all cases. High-resolution CT identified significantly more patients with CSF leak than did radionuclide cisternography and CT cisternography, with a moderate degree of agreement. CONCLUSION: Noncontrast high-resolution CT showed a defect in 70% of the patients with CSF leak. No radionuclide cisternography or CT cisternography study produced positive results without previous visualization of a defect on high-resolution CT. CT cisternography and radionuclide cisternography may be reserved for patients in whom initial high-resolution CT does not identify a bone defect or for patients with multiple fractures or postoperative defects.

The functional shift of the mandible in unilateral posterior crossbite and the adaptation of the temporomandibular joints: a pilot study. (3/406)Changes in the functional shift of the mandibular midline and the condyles were studied during treatment of unilateral posterior crossbite in six children, aged 7-11 years. An expansion plate with covered occlusal surfaces was used as a reflex-releasing stabilizing splint during an initial diagnostic phase (I) in order to determine the structural (i.e. non-guided) position of the mandible. The same plate was used for expansion and retention (phase II), followed by a post-retention phase (III) without the appliance. Before and after each phase, the functional shift was determined kinesiographically and on transcranial radiographs by concurrent recordings with and without the splint. Transverse mandibular position was also recorded on cephalometric radiographs. Prior to phase I, the mandibular midline deviated more than 2 mm and, in occlusion (ICP), the condyles showed normally centred positions in the sagittal plane. With the splint, the condyle on the crossbite side was displaced 2.4 mm (P < 0.05) forwards compared with the ICP, while the position of the condyle on the non-crossbite side was unaltered. After phase III, the deviation of the midline had been eliminated. Sagittal condylar positions in the ICP still did not deviate from the normal, and the splint position was now obtained by symmetrical forward movement of both condyles (1.3 and 1.4 mm). These findings suggest that the TMJs adapted to displacements of the mandible by condylar growth or surface modelling of the fossa. The rest position remained directly caudal to the ICP during treatment. Thus, the splint position, rather than the rest position should be used to determine the therapeutic position of the mandible.

Supporting cells contribute to control of hearing sensitivity. (4/406)The mammalian hearing organ, the organ of Corti, was studied in an in vitro preparation of the guinea pig temporal bone. As in vivo, the hearing organ responded with an electrical potential, the cochlear microphonic potential, when stimulated with a test tone. After exposure to intense sound, the response to the test tone was reduced. The electrical response either recovered within 10-20 min or remained permanently reduced, thus corresponding to a temporary or sustained loss of sensitivity. Using laser scanning confocal microscopy, stimulus-induced changes of the cellular structure of the hearing organ were simultaneously studied. The cells in the organ were labeled with two fluorescent probes, a membrane dye and a cytoplasm dye, showing enzymatic activity in living cells. Confocal microscopy images were collected and compared before and after intense sound exposure. The results were as follows. (1) The organ of Corti could be divided into two different structural entities in terms of their susceptibility to damage: an inner, structurally stable region comprised of the inner hair cell with its supporting cells and the inner and outer pillar cells; and an outer region that exhibited dynamic structural changes and consisted of the outer hair cells and the third Deiters' cell with its attached Hensen's cells. (2) Exposure to intense sound caused the Deiters' cells and Hensen's cells to move in toward the center of the cochlear turn. (3) This event coincided with a reduced sensitivity to the test tone (i.e., reduced cochlear microphonic potential). (4) The displacement and sensitivity loss could be reversible. It is concluded that these observations have relevance for understanding the mechanisms behind hearing loss after noise exposure and that the supporting cells take an active part in protection against trauma during high-intensity sound exposure.

A gene for fluctuating, progressive autosomal dominant nonsyndromic hearing loss, DFNA16, maps to chromosome 2q23-24.3. (5/406)The sixteenth gene to cause autosomal dominant nonsyndromic hearing loss (ADNSHL), DFNA16, maps to chromosome 2q23-24.3 and is tightly linked to markers in the D2S2380-D2S335 interval. DFNA16 is unique in that it results in the only form of ADNSHL in which the phenotype includes rapidly progressing and fluctuating hearing loss that appears to respond to steroid therapy. This observation suggests that it may be possible to stabilize hearing through medical intervention, once the biophysiology of deafness due to DFNA16 is clarified. Especially intriguing is the localization of several voltage-gated sodium-channel genes to the DFNA16 interval. These cationic channels are excellent positional and functional DFNA16 candidate genes.

MRI examination of the masticatory muscles in the gray wolf (Canis lupus), with special reference to the M. temporalis. (6/406)We examined the head of the gray wolf (Canis lupus) using MRI methods. Although the arising surface of the M. temporalis was not so enlarged in the frontal bone, the small frontal bone did not disturb the M. temporalis from occupying the lateral space of the frontal area in the gray wolf as in the domesticated dog. In the gray wolf, it is suggested that the M. temporalis may not be well-developed in terms of size of arising area, but in the thickness of running bundles. We suggest that the dog has changed the three-dimensional plan of the M. temporalis during the domestication and that the M. temporalis has developed a large arising surface in the frontal bone and lost the thickness of belly in the frontal area in accordance with the enlargement of the frontal bone and the increase in brain size.

Chondroblastoma of the temporal bone: a clinicopathologic study of five cases. (7/406)Chondroblastoma is a rare benign bone tumor. It commonly affects the epiphysis of long bones during the second and third decades of life. Chondroblastoma of the temporal bone is extremely rare. We reviewed five cases of chondroblastoma arising in the temporal bone. Four cases were female and one was male. The ages ranged from 41 to 60 years (mean, 53.6 years). All cases involved the temporal bone. Three involved the left side and two the right. Chief complaints were long-standing localized pain and hearing difficulty. A sharply demarcated lobulated mass was the main radiological finding. Microscopic findings were those of chondroblastoma of usual locations. Two cases showed aneurysmal bone cyst-like areas. Immunohistochemical studies for CD34, CD99, S-100 protein and cytokeratin were performed. Tumor cells were diffusely positive for S-100 protein in three cases and weakly positive for cytokeratin in one case. CD34 and CD99 were negative in all cases. In summary, chondroblastoma of the temporal bone is rare and occurs in older age group than reported cases of chondroblastoma of the usual location in the literature. (+info)
Sound- and pressure-induced vertigo associated with dehiscence of the roof of the superior semicircular canal. (8/406)In many types of peripheral vertigo, imaging is not part of the initial evaluation. We present a patient with sound- and pressure-induced vertigo associated with bony dehiscence of the roof of the superior semicircular canal. The diagnosis of this new entity can only be made by high-resolution coronal CT imaging of the temporal bones. In patients with this symptom complex, CT should be performed early in the diagnostic workup. (+info)

DSpace at EWHA: Vestibular Schwannoma Atypically Invading Temporal Bone
Vestibular schwannoma (VS) usually present the widening of internal auditory canal (IAC), and these bony changes are typically limited to IAC, not extend to temporal bone. Temporal bone invasion by VS is extremely rare. We report 51-year-old man who revealed temporal bone destruction beyond IAC by unilateral VS. The bony destruction extended anteriorly to the carotid canal and inferiorly to the jugular foramen. On histopathologic examination, the tumor showed typical benign schwannoma and did not show any unusual vascularity or malignant feature. Facial nerve was severely compressed and distorted by tumor, which unevenly eroded temporal bone in surgical field. Vestibular schwannoma with atypical invasion of temporal bone can be successfully treated with combined translabyrinthine and lateral suboccipiral approach without facial nerve dysfunction. Early detection and careful dissection of facial nerve with intraoperative monitoring should be considered during operation due to severe adhesion and ...

Temporal bone - Simple English Wikipedia, the free encyclopedia
The temporal bones are at the sides and base of the skull. They protect the structures of the inner ear. The lower seven cranial nerves move along the inside of the temporal bones. The main blood vessels to and from the brain also move along the inside of the temporal bone. The temporal bones are not the same in all mammals. The inner ear is usually not protected in marsupials, and in other placentals it is protected by a structure called the auditory bulla. ...

The identification of bone regions for the assistance of temporal bone surgery through analysis of the drill acoustics -...
This paper presents a method to identify the bone regions encountered during a temporal bone dissection. This should aid the otolaryngologist in the identification of anatomical landmarks whilst training and performing surgical procedures. The approach adopts the mel frequency cepstrum coefficients and the Mahalanobis distance metric to indentify the temporal bone regions from the acoustic signature of the surgical drill. Audio data from a mastoidectomy, that involved the dissection of the sigmoid sinus, thin tegmen and thick tegmen bone regions with diamond and cutting type burrs of sizes 6mm, 3mm and 1mm were analysed. An identification accuracy of 97.72 ± 1.77 % was achieved with the mel frequency cepstrum approach. This is a significant improvement over the previous approach that utilises the power spectral density and the correlation coefficient to identify the same bone regions only 90.59 ± 1.58 % of the time. Three case studies were considered as a feasibility study for the

The pilot subsequently telephoned to inform me that the radiologist had diagnosed Eagles syndrome. The CT scan reported: There is an incidental finding of an elongated partially calcified left stylohyoid ligament (known as eagle syndrome). The pilot added that his haematologist had conducted a preliminary search about Eagles syndrome, which raised concerns about potential complications and as a result his haematologist referred him to a vascular surgeon.. The first three webpages generated by a Google™ search of Eagles syndrome indicated that potential complications could include transient ischaemic attacks, carotid artery dissection, syncope and sudden death.2-4.

VIRTUAL GRAND ROUNDS IN DERMATOLOGY 2.0: Post-Auricular Basal Cell
Abstract: Basal cell carcinomas involving the ear represent a spectrum of diseases, from a small superficial auricular lesion to an advanced destructive malignancy invading the temporal bone. The biologic activity of the morphea-form basal cell carcinoma variant of tumor and a postauricular location predispose to an aggressive biologic pattern. Management requires a thorough evaluation with determination of the degree of cranial and possible intracranial invasion. These lesions usually can be managed with partial temporal bone resections, although prognosis for patients with advanced lesions may be poor ...

Temporal bone - Wikipedia
The tympanic ring is an incomplete circle, in the concavity of which is a groove, the tympanic sulcus, for the attachment of the circumference of the eardrum (tympanic membrane). This ring expands to form the tympanic part, and is ossified in membrane from a single center which appears about the third month. The styloid process is developed from the proximal part of the cartilage of the second branchial or hyoid arch by two centers: one for the proximal part, the tympanohyal, appears before birth; the other, comprising the rest of the process, is named the stylohyal, and does not appear until after birth. The tympanic ring unites with the squama shortly before birth; the petromastoid part and squama join during the first year, and the tympanohyal portion of the styloid process about the same time [Fig. 7, 8]. The stylohyal does not unite with the rest of the bone until after puberty, and in some skulls never at all ...
Old bone dates human hand evolution | Liquid Level Sensing
The styloid process can be clearly seen in the Kaitio bone. Prof Carol Ward and her colleagues note that a lack of the styloid process created challenges for apes and earlier humans when they attempted to make and use tools. This lack of a styloid process may have increased the chances of having arthritis earlier.. Prof Ward, professor of pathology and anatomical sciences at the University of Missouri, Columbia, said: The styloid process reflects an increased dexterity that allowed early human species to use powerful yet precise grips when manipulating objects. This was something that their predecessors couldnt do as well due to the lack of this styloid process and its associated anatomy.. With this discovery, we are closing the gap on the evolutionary history of the human hand. This may not be the first appearance of the modern human hand, but we believe that it is close to the origin, given that we do not see this anatomy in any human fossils older than 1.8 million years.

Diagnosis is suspected when a patient presents with the symptoms of the classic form of Eagle syndrome e.g. unilateral neck pain, sore throat or tinnitus. Sometimes the tip of the styloid process is palpable in the back of the throat. The diagnosis of the vascular type is more difficult and requires an expert opinion. One should have a high level of suspicion when neurological symptoms occur upon head rotation. Symptoms tend to be worsened on bimanual palpation of the styloid through the tonsillar bed. They may be relieved by infiltration of lidocaine into the tonsillar bed. Because of the proximity of several large vascular structures in this area this procedure should not be considered to be risk free. Imaging is important and is diagnostic. Visualizing the styloid process on a CT scan with 3D reconstruction is the suggested imaging technique. The enlarged styloid may be visible on an orthopantogram or a lateral soft tissue X ray of the neck. It is worth noting that the styloid may be ...

Essential MS - Dr. David E. Williams - Multiple Sclerosis Research
ABSTRACT: In this study, the authors investigated the link between jaw clenching/bruxism and temporal bone movement associated with multiple sclerosis (MS). Twenty-one subjects participated in this study (10 patients with MS and 11 controls). To quantify the change in intracranial dimension between the endocranial surfaces of the temporal bones during jaw clenching, an ultrasonic pulsed phase locked loop (PPLL) device was used. A sustained jaw clenching force of 100 lbs was used to measure the mean change in acoustic pathlength (∆L) as the measure of intracranial distance. In the control subjects the mean ∆L was 0.27 mm±0.24. In subjects with MS the mean ∆L was 1.71 mm±1.18 (p , 0.001). The increase in magnitude of bi-temporal bone intracranial expansion was approximately six times greater in subjects with MS compared to controls. Therefore, jaw clenching/bruxism is associated with more marked displacement of the temporal bones and expansion of the cranial cavity in patients with MS than ...

On a worldwide basis, there are only a few case reports of otopathology in patients with genetic deafness where the precise genetic mutation was known. Given the variant clinical expressions of syndromes of genetic deafness, it becomes urgent to provide pathologic profiles that can be matched to the genetic abnormalities. Without this knowledge, it will be difficult to ultimately devise strategies for overcoming the genetic defects. Animal models, including knockouts, knockins, and naturally occurring mutants are being increasingly used to investigate the genetics of hearing loss. Such models can provide valuable information regarding the molecular bases of auditory and vestibular disorders, but remains important to verify the validity of these models by comparison with the otopathology as determined in human cases ...

Is there a bird in my head? - Proscan Imaging
2 - Due to compression of the carotid arteries. Cranial nerve impingement symptoms typically include facial pain when turning the head, dysphagia, foreign body sensation, pain on extending the tongue, change in voice, sensation of hypersalivization, and/or tinnitus/otalgia. On palpation of the styloid process tips, symptoms should ideally be exaggerated.. Arterial impingement symptoms include mechanical compression which would result in visual symptoms, syncope, carotid dissection, or sympathetic plexus irritation (carotodynia) such as eye pain or parietal pain.. Radiographic features of Eagle syndrome include styloid processes longer than 3cm which can be either unilateral or bilateral. Sometimes, styloid processes are elongated or the stylohyoid ligament is calcified.. Typical treatment includes transpharyngeal injection of steroids/local anesthetic agents. Severe cases would involve surgical excision either via transoral approach or a lateral approach. Transoral approach has the disadvantage ...
Safety studies and preliminary patient trails with a new perimodiolar electrode array
A new perimodiolar electrode array, the curly-with stylet (CwS), has been developed and undergone safety trials in human cadaver temporal bones. The array was developed as a result of animal and modelling studies which indicated that there are potential advantages in situating the electrode array in closer proximity to the neural elements. Preliminary studies with four patients in Melbourne implanted with a developmental pre-curved array had supported the predictions of lower current requirements and possibly more focussed spread of excitation ...
The Evolution of Cervical...
I started out treatment with Standing Supported Wall Squat and Reach and Modified All Four Belly Lift which resulted in about a 50% improvement in his testing. I then had him remove his Invisalign retainer and his testing went to neutral. However, he was unable to reciprocally find his bite. This means he was unable to make contact on one side of his molars without contact on the other side. Regarding his cranio-mandibular positioning, his mandible was centered and his cant seemed fairly even (it may have been being marginally higher on the right). His right temporal bone was observed to be in a little more external rotation/flexion compared to his left. For those that have taken Cervical Revolution, this indicates he may be in a right torsion cranial pattern but it appeared mild. His bite was Class 1 with canine guidance during full laterotrusion and no interferences bilaterally. This means he had good occlusion and range of motion ...

TY - JOUR. T1 - Ontogenetic change in temporal bone pneumatization in humans. AU - Hill, Cheryl A. PY - 2011/7. Y1 - 2011/7. N2 - Pneumatization of the temporal bone is often included in descriptions of fossils and as a phylogenetic marker, but a number of questions about the evolution, growth, and development of the trait remain. Many studies have analyzed temporal bone pneumatization from a clinical perspective, but a systematic quantification of normal development of pneumatized spaces has not been conducted. In this study, ontogenetic change in the size and organization of temporal bone pneumatization is analyzed in a cross-sectional sample of humans. High resolution computed tomography scans of the temporal bone were acquired from a cross-sectional sample of humans (N = 28). Bone volume fractions, anisotropy, trabecular number, trabecular thickness, surface area, and volume were analyzed to provide information about the organization and size of pneumatized spaces across ontogeny.

Post-traumatic bilateral longitudinal temporal bone fracture with bilateral facial nerve palsy: a rare case | BMJ Case Reports
Facial paralysis is a potentially disabling complication of temporal bone fractures. Although unilateral palsy is commonly encountered, bilateral facial nerve palsy is rare, especially in post-traumatic situations. Other recognised causes of bilateral facial palsy are neurologic, infectious, neoplastic, idiopathic or metabolic disorders. A 25-year-old male patient presented with difficulty in talking, eating and closing eyes for 15 days since a post-vehicular accident. CT of skull showed bilateral longitudinal temporal bone fractures. Bilateral facial palsy was confirmed by clinical and topodiagnostic tests. Patient was given a course of steroids which led to an early improvement on left side followed by a delayed right-sided improvement at 6 months. ...
Surface and curve skeleton from a structure tensor analysis applied on mastoid air cells in human temporal bones
The mastoid of human temporal bone contains numerous air cells connected to each others. In order to gain further knowledge about these air cells, a more compact representation is needed to obtain an estimate of the size distribution of these cells. Already existing skeletonization methods often fail in producing a faithful skeleton mostly due to noise hampering the binary representation of the data. This paper proposes a different approach by extracting geometrical information embedded in the Euclidean distance transform of a volume via a structure tensor analysis based on quadrature filters, from which a secondary structure tensor allows the extraction of surface skeleton along with a curve skeleton from its eigenvalues. Preliminary results obtained on a X-ray micro-CT scans of a human temporal bone show very promising results.. ...

Ear and Temporal Bone Cancer | Center for Neurosciences
Primary cancers of the ear canal are rare; however, when they do occur, basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) are the typical culprits. Cancers involving the outer ear (pinna) are more common and arise due to sun exposure (especially common in the desert Southwest). Dermatologists typically manage routine skin cancers of the outer ear; however, large tumors require multi-disciplinary care including a neurotologist. BCCs and SCCs arising in the temporal bone (ear canal) occur spontaneously and can spread quickly to adjacent areas like the parotid gland (salivary gland anterior to the ear canal), the neck (inferior to the ear canal), the middle ear (deep/medial to the ear canal) or the mastoid (posterior to the ear canal). Significant delays in treatment can result in metastases to other locations throughout the body.. If ear cancer is suspected, a biopsy of the lesion is performed to confirm the diagnosis. Imaging studies such as temporal bone CT scans, PET scans, ...
CD-ROM REVIEW, Temporal Bone Dissector | Journal of Neurology, Neurosurgery & Psychiatry
The advances of medicine in the past two decades have been very rapid and exciting and hand in hand with this has gone advances in audiovisual aids and teaching. The technology that has brought the computer into most households has been truly amazing particularly for those of us who lived before the birth of the computer. This has led to a revolution in information technology and inter-communication. The world now seems a very small place, the Internet and the World Wide Web has ensured that this is the case but it has also led to the instant availability of a vast sea of knowledge about all aspects of life.. There are now new horizons in audio-visual technology and these can be utilised to teach both undergraduates and postgraduates. There are some that would say that the old fashioned apprenticeship is the gold standard in surgery but this CD-ROM by Blevins, Jackler, and Gralapp is an attempt to use computer technology to teach young surgeons the anatomy of the temporal bone and temporal bone ...

Bone remodeling within the otic capsule has been reported to be inhibited especially at or near the cochlea, except under some pathological conditions such as otosclerosis, Pagets disease, or mastoiditis, when bone remodeling can occur. Microcavitations found in periosteal and endosteal layers of human temporal bone specimens without otosclerosis, Pagets disease, or inflammation as reported in the current study are consistent with osteoclastic bone resorption. Thirty-three temporal bones from 33 patients were prepared for light microscopy and classified into 4 groups: histologically proven dehiscence of the superior semicircular canal (SSCD) (n = 3, group 1), age 20 years or younger (n = 10, group 2), age 90 years or older and with otosclerosis (n = 10, group 3), and age 90 years or older without otosclerosis (n = 10, group 4 ...
Hearing loss in relation to round window membrane morphology in experimental chronic otitis media
Topical treatment of several inner ear diseases through the round window membrane (RWM) might be feasible in the near future. Bacteria toxins, ototoxic drugs and noise trauma seem to harm the inner ear by a common pathway which involves, excessive outflow of the afferent neurotransmitter glutamate and formation of nitric oxide (NO), which can severely damage cells/nerve endings and lead to cell death.. In this study we used 98 Sprague-Dawley rats and seven human temporal bones. Various substances were instilled into the middle ear of the rat, such as Pseudomonas Aeruginosa Exotoxin (PaExoA), gentamicin, NO-inhibitor N-Omega-Nitro-L-Arginine Methyl Ester (L-NAME), and glucocorticoids. The effects of the substances were studied by morphological analysis of RWM and the endolymphatic sac (ES) by light and electron microscopic. Hearing level was measured in the rats by ABR technique. The human temporal bones were studied immunomorphologically to search for glutamate.. In the human inner ear, ...

Skull Anatomy | The Neurosurgical Atlas, by Aaron Cohen-Gadol, M.D.
The temporal bones are divided into the squamosal, mastoid, tympanic, styloid, and petrous segments. Each articulates with the zygomatic bone (zygomaticotemporal suture), sphenoid bone (sphenosquamosal suture), parietal bone (parietosquamous suture), and occipital bone (occipitomastoid suture).22-24 Understanding the anatomy of the temporal bone is critical to a number of open skull base approaches.26 A number of critical neurovascular structures, namely, the lower seven cranial nerves and the major vessels to and from the brain, traverse the temporal bone.. Externally, the squamous portion of the temporal bone is smooth and provides attachment for the temporalis fascia and muscle at the superior and inferior temporal lines, respectively.22 The zygomatic process, which has an anterior and posterior root, extends anteriorly and articulates with the zygomatic bone. Near the anterior root of the zygomatic process is the articular tubercle, just posterior to which is the glenoid fossa, where the ...

The disc is thick all around its rim, and thin in the centre. From anterior to posterior it shows - anterior extension, thick anterior band (2.0mm thick), intermediate thin zone (1.0 mm thick), thick posterior band (3.0 mm thick) and posterior most bilaminar region (Dubrul, 1996; Williams et al, 1999). The disc is attached all around the joint capsule except the strong straps those fix the disc directly to the medial and lateral condylar poles which ensures that the disc and condyle move together in protraction and retraction (Choukas and Sicher, 1960; Williams et al, 1999). The anterior extension of the disc is attached to fibrous capsule superiorly and inferiorly and through that to temporal bone and the mandibular neck respectively. In between it gives insertion to lateral pterygoid muscle where the fibrous capsule is lacking and synovial membrane is supported only by loose areolar tissue. In the opinion of Kreutziger and Mahan (1975), this deficiency anteriorly is the weak point since there ...

Recent E-mails - The Effects of the Supine Active Sacro-Spheno Flexion Technique on Inner Ear Function
I recently saw a patient with a diagnosis of severe CS arthritis with main complaints of numbness/tingling of her UE and ringing in her ears. It appears that the intensity of the ringing in her ears is positively affected by the supine active sacro spheno flexion activity. After this technique, the ringing is less intense. She is now beginning to be able to control it with good diaphragmatic breathing in appropriate posture. Can you help me better understand the physiology/anatomy of why this may be happening? The Supine Active Sacro-Spheno Flexion technique restores OA extension on the right, repositions the sphenoid in sagittal neutrality and in general, places the sphenoid in a state of flexion. The right temporal bone is then pulled into ER (external rotation) via the right styloid muscles. So, in essence the tensor tympanics in the temporal bones and the tensor veli palatins are re-set or repositioned to allow for normal malleus and inner ear function. Thanks for the question ...
Traumatic ossicular dislocations: etiology and management. - Semantic Scholar
OBJECTIVE This study was conducted to discuss the etiologic factors, clinical-radiologic findings, and surgical outcomes in patients with traumatic ossicular pathology. MATERIAL AND METHODS Thirty-two patients with conductive hearing loss due to trauma were retrospectively analyzed. Their mean age was 24.56 +/- 7 years. The average delay from injury until treatment was 5.7 years. Air and bone conduction hearing thresholds were measured by pure tone audiometry on initial admission, at 1 month postoperatively and during follow-up at 6-month intervals. Mean follow-up time is 3.2 years. The hearing threshold was calculated as the mean value of the threshold for 500, 1000, 2000, and 3000 Hertz. All patients were evaluated by high-resolution computerized tomography of the temporal bone at axial and coronal sections before the surgery. RESULTS Traffic accident was the common cause of injury. Seven patients had temporal bone fracture. Six patients had facial paralysis ranging between House-Brackmann grades

An unusual internal carotid artery compression as a possible cause of Eagle syndrome - A novel hypothesis and an innovative...
Background: Eagle syndrome (ES) is a rare symptomatic condition generally caused by an elongated styloid process (SP) or calcification of the stylohyoid complex. On the diagnosis is made, its treatment remains subjective since the indications for surgical intervention are still not standardized. Although styloidectomy is the surgical treatment of choice, no consensus exists regarding the transcervical or/and transoral route. Here, we report our experience in a patient with bilateral internal carotid artery (ICA) dissection caused by ES, who underwent innovative surgical technique. Case Description: A 53-year-old man, with the right-sided middle cerebral artery acute stroke, underwent computed tomography angiography 3 days after a successful endovascular treatment. The study showed a bilateral ICA dissection with bilateral hypertrophic SPs and a close relationship of ICAs with both SPs anteriorly and C1 transverse process posteriorly. Considering the occurrence of ICA compression by a styloid/C1 ...

Bone Study 1 - AlgaeCal
This human study involving more than 200 women and men found that AlgaeCal formulations increased bone density by more than 2% on average. To gain bone density at all is an unusual finding as humans normally lose approximately 1% of bone each year after age 40. This open label study measured bone density of participants at the beginning, then again after six months of taking AlgaeCal formulations (including strontium).. The primary outcome measure was bone mineral density and a secondary measure was safety as reported in a panel of 43 blood tests along with quality of life questionnaire. Calcium studies often report an increase in bone density, but it is never an outright increase - it is an increase compared to the placebo group which is declining - so the participants are actually losing bone. This study is a landmark result with a real increase in BMD.. ...
Effective February 7, 2011, PET/CT bone scans utilizing the radiopharmaceutical 18F- Sodium Fluoride (NaF) are covered for Medicare beneficiaries through the Coverage with Evidence Development/National Oncologic PET Registry (NOPR) program for the detection of bone metastases. 18F-Sodium Fluoride (NaF) PET/CT bone scans are an important tool for detecting and evaluating metastatic bone cancer. These bone studies are particularly useful, since some of the most prevalent cancers are commonly associated with metastatic bone disease, such as breast and prostate cancer, as well as carcinoma of the thyroid, kidney, and lung. Examples of tumor type and ICD-9-CM codes for 18F-Sodium Fluoride (NaF) PET/CT bone studies are as follows:. ...
MATERIALS AND METHODS: We retrospectively reviewed 112 consecutive patients (224 ears) with vestibulocochlear symptoms who underwent concurrent MR imaging and CT of the temporal bones between 2007 and 2009. MR imaging protocol included a FIESTA sequence covering the temporal bone (axial 0.8-mm section thickness, 0.4-mm spacing, coronal/oblique reformations; 41 patients at 1.5T, 71 patients at 3T). CT was performed on a 64-row multidetector row scanner (0.625-mm axial acquisition, with coronal/oblique reformations). Both ears of each patient were evaluated for dehiscence of the superior and posterior semicircular canals in consensual fashion by 2 neuroradiologists. Analysis of the FIESTA sequence and reformations was performed first for the MR imaging evaluation. CT evaluation was performed at least 2 weeks after the MR imaging review, resulting in a blinded comparison of CT with MR imaging. CT was used as the reference standard to evaluate the MR imaging results.. ...

Let it Be: The Best Treatment for TMJ | deletia.org
The TMJ is responsible for the hinge and sliding motion of the mouth. When our mouths open, the rounded ends (condyles) of your lower jaw will glide through the sockets of your temporal bones. The muscles are connected to the temporal bones and the jaw with a soft disc placed in between to absorb the shocks from all jaw movements.. TMJ disorders were first thought to branch from upper and lower teeth misalignment (malocclusion) or improper jaw position. This is the reason why dentists focused on replacing teeth that are missing and applying braces to correct the persons teeth alignment and change how the jaws meet.. Recent studies show that malocclusion is also part of TMJ symptoms. This means that braces or replacing teeth wont really solve the TMJ disorder, it only is a product of the disorder along with many other symptoms and factors. The American Academy of Orofacial pain said that TMJ usually involves many symptoms and rarely branches from a single cause.. There are other causes that are ...

Most recent papers with the keyword sensory nerve and bone | Read by QxMD
Electric stimulation of the auditory nerve by cochlear implants has been a successful clinical intervention to treat the sensory neural deafness. In this pathological condition of the cochlea, type-1 spiral ganglion neurons in Rosenthals canal play a vital role in the action potential initiation. Various morphological studies of the human temporal bones suggest that the spiral ganglion neurons are surrounded by heterogeneous structures formed by a variety of cells and tissues. However, the existing simulation models have not considered the tissue heterogeneity in the Rosenthals canal while studying the electric field interaction with spiral ganglion neurons ...
Determination of drill paths for percutaneous cochlear access accounting for target positioning error | (2007) | Noble | ...
In cochlear implant surgery an electrode array is permanently implanted to stimulate the auditory nerve and allow deaf people to hear. Current surgical techniques require wide excavation of the mastoid region of the temporal bone and one to three hours time to avoid damage to vital structures. Recently a far less invasive approach has been proposed-percutaneous cochlear access, in which a single hole is drilled from skull surface to the cochlea. The drill path is determined by attaching a fiducial system to the patients skull and then choosing, on a pre-operative CT, an entry point and a target point. The drill is advanced to the target, the electrodes placed through the hole, and a stimulator implanted at the surface of the skull. The major challenge is the determination of a safe and effective drill path, which with high probability avoids specific vital structures-the facial nerve, the ossicles, and the external ear canal-and arrives at the basal turn of the cochlea. These four features lie ...

anatomyEXPERT - Temporalis - Structure Detail
In English, this muscles name is the time muscle. The word temporalis comes from the Latin word tempus meaning time.

Therefore, this region is the first to show the ravages of time ...

Autism/ADD/ADHD - Healing Dynamics
Dr. John Upledger, DO, of the Upledger Institute in Florida discovered that the craniums of these children are very tight with little or no movement at the sutures. This is especially so for the temporal bone. Releasing this bone on both sides of the cranium at its sutural link to the sphenoid in front, the parietal bone above and the occiput behind, is all that it takes to set free the cranial vault in order to decrease the pressure on the internal milieu of the brain. This has such a powerful effect, that these children have even been able to integrate into normal classrooms.The method described above is known as craniosacral therapy. Along with this using techniques to teach sensory integration, more or less completes the circle of healing. There is also lymph drainage therapy that offers relief through drainage of the dura, a tissue that completely encases the brain. This helps in decongesting the brain and brings relief from decreased pressure. A synthesis of all these techniques is what ...

Preoperative prediction by artificial intelligence for mastoid extension in pars flaccida cholesteatoma using temporal bone...
Cholesteatoma is a progressive middle ear disease that can only be treated surgically but with a high recurrence rate. Depending on the extent of the disease, a surgical approach, such as microsurgery with a retroarticular incision or transcanal endoscopic surgery, is performed. However, the current examination cannot sufficiently predict the progression before surgery, and changes in approach may be made during the surgery. Large amounts of data are typically required to train deep neural network models; however, the prevalence of cholesteatomas is low (1-in-25, 000). Developing analysis methods that improve the accuracy with such a small number of samples is an important issue for medical artificial intelligence (AI) research. This paper presents an AI-based system to automatically detect mastoid extensions using CT. This retrospective study included 164 patients (80 with mastoid extension and 84 without mastoid extension) who underwent surgery. This study adopted a relatively lightweight neural
