Formation or presence of a blood clot (THROMBUS) in the LATERAL SINUSES. This condition is often associated with ear infections (OTITIS MEDIA or MASTOIDITIS) without antibiotic treatment. In developed nations, lateral sinus thrombosis can result from CRANIOCEREBRAL TRAUMA; BRAIN NEOPLASMS; NEUROSURGICAL PROCEDURES; THROMBOPHILIA; and other conditions. Clinical features include HEADACHE; VERTIGO; and increased intracranial pressure.

Noise level of drilling instruments during mastoidectomy. (1/118)

Exposure to intense noise has been identified as a potential risk in the development of hearing impairment. Social concern about excessive noise is increasing and this also extends to the operating room. A noise level study was performed in the operating room during mastoidectomy with a sound level meter and it was analyzed by a sound-analyzing program. The drilling instruments used included the Stryker, Midas, M.P.S. and Med-Next. The operator was exposed to sound levels from 69 to 83 dBA. The loudest drilling instrument was the Midas and it produced an average sound level of 83 dBA to the operator. The mean exposure time was 41 minutes during mastoidectomy. This is below the occupational noise-level regulations in Korea. However, considering that individual susceptibility to noise varies and that the otologic surgeon is repeatedly exposed to prolonged drilling noise, ear protection is recommended for the operators of high-speed drilling instruments.  (+info)

Random errors in localization of landmarks in postero-anterior cephalograms. (2/118)

The aim of the present study was to evaluate the random error in localization of the most common landmarks in postero-anterior cephalograms (PAC). The study took place at the Department of Orthodontics of Aarhus University during the period 1993-1995. The material consisted of 30 standardized PAC taken in natural head position. Five examiners had to identify 34 landmarks on each cephalogram. Subsequently, all examiners had to identify again the same 34 landmarks on one randomly selected cephalogram five times with a time interval of at least 24 hours. All landmarks were digitized, related to an X-Y co-ordinate system, and an arithmetical mean was calculated. The accuracy of digitizing was evaluated by digitizing one randomly selected cephalogram 10 times. The main findings of this study are: (1) The digitizing error is negligible compared to the errors introduced by landmark identification. (2) Each landmark has its own characteristic pattern of variance, which is very similar on both sides. (3) Significant differences in accuracy exist between the various postero-anterior landmarks. The six most accurate landmarks are mastoid left (l) and right (r), latero-orbitale (l) and (r), and antegonion (l) and (r). The six least accurate landmarks are coronoid (l) and (r), condylar (l) and (r), and mandibular foramen (l) and (r). (4) A significant difference in the accuracy of landmark identification between the five examiners was only seen for seven of the 34 landmarks. (5) No evidence was found that one examiner was consistently better/worse than the others. (6) No improvement in the accuracy was found after repeated identification, thus there seems to be no short-term 'learning process'. Refereed Paper  (+info)

Multisensory cortical signal increases and decreases during vestibular galvanic stimulation (fMRI). (3/118)

Functional magnetic resonance imaging blood-oxygenation-level-dependent (BOLD) signal increases (activations) and BOLD signal decreases ("deactivations") were compared in six healthy volunteers during galvanic vestibular (mastoid) and galvanic cutaneous (neck) stimulation in order to differentiate vestibular from ocular motor and nociceptive functions. By calculating the contrast for vestibular activation minus cutaneous activation for the group, we found activations in the anterior parts of the insula, the paramedian and dorsolateral thalamus, the putamen, the inferior parietal lobule [Brodmann area (BA) 40], the precentral gyrus (frontal eye field, BA 6), the middle frontal gyrus (prefrontal cortex, BA 46/9), the middle temporal gyrus (BA 37), the superior temporal gyrus (BA 22), and the anterior cingulate gyrus (BA 32) as well as in both cerebellar hemispheres. These activations can be attributed to multisensory vestibular and ocular motor functions. Single-subject analysis in addition showed distinctly nonoverlapping activations in the posterior insula, which corresponds to the parieto-insular vestibular cortex in the monkey. During vestibular stimulation, there was also a significant signal decrease in the visual cortex (BA 18, 19), which spared BA 17. A different "deactivation" was found during cutaneous stimulation; it included upper parieto-occipital areas in the middle temporal and occipital gyri (BA 19/39/18). Under both stimulation conditions, there were signal decreases in the somatosensory cortex (BA 2/3/4). Stimulus-dependent, inhibitory vestibular-visual, and nociceptive-somatosensory interactions may be functionally significant for processing perception and sensorimotor control.  (+info)

Unexpected reflex response to transmastoid stimulation in human subjects during near-maximal effort. (4/118)

1. In human subjects, a high-voltage electrical pulse between electrodes fixed over the mastoid processes activates descending tract axons at the level of the cervico-medullary junction to produce motor responses (cevicomedullary evoked responses; CMEPs) in the biceps brachii and brachioradialis muscles. 2. During isometric maximal voluntary contractions (MVCs) of the elbow flexors, CMEPs in the biceps brachii and brachioradialis muscles are sometimes followed by a second compound muscle action potential. This response can be observed in single trials (amplitude of up to 60 % of the maximal M wave) and follows the CMEP by about 16 ms in both muscles. The response only occurs during very strong voluntary contractions. 3. The second response following transmastoid stimulation appears with stimulation intensities that are at the threshold for evoking a CMEP in the contracting muscles. The response grows with increasing stimulus intensity, but then decreases in amplitude and finally disappears at high stimulation intensities. 4. A single stimulus to the brachial plexus during MVCs can also elicit a second response (following the M wave) in the biceps brachii and brachioradialis muscles. The latency of this response is 3-4 ms longer than that of the second response observed following transmastoid stimulation. This difference in latency is consistent with a reflex response to stimulation of large-diameter afferents. 5. The amplitude of the second response to transmastoid stimulation can be reduced by appropriately timed subthreshold transcranial magnetic stimuli. This result is consistent with intracortical inhibition of the response. 6. We suggest that transmastoid stimulation can elicit a large transcortical reflex response in the biceps brachii and brachioradialis muscles. The response travels via the motor cortex but is only apparent during near-maximal voluntary efforts.  (+info)

Mastoid air sinus abnormalities associated with lateral venous sinus thrombosis: cause or consequence? (5/118)

BACKGROUND: Mastoiditis is a known cause of lateral venous sinus thrombosis (LST). We have encountered patients with LST associated with mastoid abnormality on MRI without any clinical signs of infection; the significance of these abnormalities is uncertain. This study examines the relationship of LST and mastoid air sinus abnormalities systematically. SUMMARY OF REPORT: We performed a retrospective clinical and radiological review of a series of 26 patients with cerebral venous thrombosis. Mastoid abnormalities were detected ipsilateral to 9 of 23 thrombosed lateral sinuses (39%) and 0 of 29 unaffected lateral sinuses (P<0.001). No patient had clinical evidence of mastoiditis. Eight of 9 patients with mastoid abnormalities were treated without antibiotics; all made uneventful clinical recoveries. Repeated MRI in 1 patient revealed reversal of the mastoid changes. CONCLUSIONS: The mastoid changes observed are likely to be due to venous congestion as a consequence of LST, not mastoiditis.  (+info)

Comparison of human ocular torsion patterns during natural and galvanic vestibular stimulation. (6/118)

Galvanic vestibular stimulation (GVS) is reported to induce interindividually variable tonic ocular torsion (OT) and superimposed torsional nystagmus. It has been proposed that the tonic component results from the activation of otolith afferents. We tested our hypothesis that both the tonic and the phasic OT are mainly due to semicircular canal (SCC) stimulation by examining whether the OT patterns elicited by GVS can be reproduced by pure SCC stimulations. Using videooculography we measured the OT of six healthy subjects while two different stimuli with a duration of 20 s were applied: 1) transmastoidal GVS steps of 2 mA with the head in a pitched nose-down position and 2) angular head rotations around a combined roll-yaw axis parallel to the gravity vector with the head in the same position. The stimulation profile was individually scaled to match the nystagmus properties from GVS and consisted of a sustained velocity step of 4-12 degrees /s on which a velocity ramp of 0.67-2 degrees /s(2) was superimposed. Since blinks were reported to induce transient torsional eye movements, the subjects were also asked to blink once 10 s after stimulus onset. Analysis of torsional eye movements under both conditions revealed no significant differences. Thus we conclude that both the tonic and the phasic OT responses to GVS can be reproduced by pure rotational stimulations and that the OT-related effects of GVS on SCC afferents are similar to natural stimulations at small amplitudes.  (+info)

Diffusion-weighted imaging for differentiating recurrent cholesteatoma from granulation tissue after mastoidectomy: case report. (7/118)

Identification of recurrent cholesteatoma and differentiation from postoperative granulation tissue is important in a patient who has undergone mastoidectomy for cholesteatoma. We describe the diffusion-weighted imaging findings and apparent diffusion coefficient values in a case of recurrent cholesteatoma. This case suggests possible differentiation of cholesteatoma from granulation tissue on the basis of diffusion-weighted imaging findings.  (+info)

Vibration-induced ocular torsion and nystagmus after unilateral vestibular deafferentation. (8/118)

Vibration is an excitatory stimulus for both vestibular and proprioceptive afferents. Vibration applied either to the skull or to the neck muscles of subjects after unilateral vestibular deafferentation induces nystagmus and a shift of the subjective visual horizontal. Previous studies have ascribed these effects to vibratory stimulation of neck muscle proprioceptors. Using scleral search coils, we recorded three-dimensional eye movements during unilateral 92 Hz vibration of the mastoid bone or of the sternocleidomastoid (SCM) muscle in 18 subjects with chronic unilateral vestibular deficits after vestibular neurectomy or neuro-labyrinthitis. Nine subjects had lost function of all three semicircular canals (SSCs) on one side, and the other nine had lost function of only the anterior and lateral SSCs. Vibration of the mastoid bone or of the SCM muscle on either side induced an ipsilesional tonic shift of torsional eye position of up to 6.5 degrees during visual fixation, as well as a nystagmus with horizontal, vertical and torsional components in darkness. Subjects who had lost function of all three SSCs on one side showed a larger shift in ocular torsion in response to SCM vibration than did subjects who had lost function of only two SSCs. The difference between ocular torsion produced by ipsilesional muscle or bone vibration was not significantly different from that produced by contralesional bone or muscle vibration. The vibration-induced nystagmus rotation axis tended to align with the pitch (y) axis of the head in subjects who had lost only anterior and lateral SSC function, and with the roll (x) axis of the head in subjects who had lost function of all three SSCs. We propose that the previously described vibration-induced shift of the subjective visual horizontal can be explained by the vibration-induced ocular torsion, and that the magnitude of ocular torsion is related to the extent of the unilateral vestibular deficit. While altered proprioceptive inputs from neck muscles might be important in the mechanism of vibration-induced ocular torsion and nystagmus after unilateral vestibular deafferentation, vibratory stimulation of vestibular receptors in the intact labyrinth also appears to have an important role.  (+info)

The effect of mastoid sclerosis on bone-conduction threshold sensitivity was assessed by retrospective comparison of audiologic data from 14 persons with unilateral mastoid sclerosis and 13 persons with normally pneumatized mastoids. All subjects with normal mastoids had unilateral sensorineural loss; most sclerotic mastoid subjects had normal hearing in the ear associated with a normally pneumatized mastoid and mixed or pure sensorineural loss on the sclerotic side. Mean interaural threshold differences and distributions of differences were similar for both groups. Sclerotic mastoids do not appear to have a significant effect on bone-conduction thresholds.. ...

The mastoid air cells are a collection of air-filled spaces located in the mastoid process of the temporal bone. They communicate with the middle ear via a small canal known as the aditus to mastoid antrum.. Infection can spread from the middle ear into the mastoid air cells causing infection of the bone of the mastoid air cells. This in turn leads to breakdown of the fine trabeculae of the mastoid air cells along with collection of pus in the mastoid antrum. As the pus is enclosed under pressure, this causes localised bone necrosis, which can spread to form a sub-periosteal abscess.. The abscess can usually be found in 1 of 3 places:. ...

After 4 surgeries on his mastoid bone behind his right ear, Nate was diagnosed with Langerhans Cell Histiocytosis in Feb 2017. Nates journey started with a misdiagnosed ear infection that drained backwards and eroded his mastoid bone (part of his skull). After removing the mass from the mastoid bone behind his ear, the granulation tissue kept re-growing within 2 to 3 weeks. After 3 surgeries at Hersheys Medical Center, Nate went to CHOP Childrens Hospital of Philadelphia for a second opinion. We met with an ENT doctor at CHOP in Jan 2017. The ENT doctor was not sure what Nate was experiencing so we prayed for a proper diagnosis. Luckily, we received a proper diagnosis in Feb 2017 and began our daily chemo treatment in March 2017. Thankfully the LCH appears to only be in the mastoid bone. The bone erosion has stopped and we seem to be in a good place after 5 months of chemo.

In medical terminology, Battles sign, also mastoid ecchymosis, is an indication of fracture of middle cranial fossa of the skull, and may suggest underlying brain trauma. Battles sign consists of bruising over the mastoid process, as a result of extravasation of blood along the path of the posterior auricular artery.[1] The sign is named after William Henry Battle.[2] Note well that this sign will take at least one day to appear after the initial traumatic basilar skull fracture, similar to Raccoon eyes.[3] Battles sign is usually seen after head injuries resulting in injury to mastoid process leading to bruising.. Battles sign may be confused with a spreading hematoma from a fracture of the mandibular condyle,[4] which is a less serious injury.. ...

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.. ...
We studied the extra cranial portion of the internal carotid artery and structures associated with it, which are vulnerable to iatrogenic injury during surgical approach to the neck region in 18 individuals. Distances from the origin of the artery to hypoglossal nerve and posterior belly of digastric muscle were measured. The mastoid process and the hyoid bone were also used as landmarks in locating the nerve and respective distances measured. Hypoglossal nerve and posterior belly of digastric muscle crossed the ICA at variable positions with a mean distance of 10.1mm and 17.9mm respectively from the common carotid bifurcation. From the mastoid process, the internal carotid artery ascends underneath the posterior belly of the digastric muscle a third the distance to the hyoid bone. The external carotid artery is located lateral to the internal carotid artery in 63.8% of the cases, posterior in 16.7% and anterior in 19.4%. The posterior belly of digastric muscle and its attachments are key ...
Background: The introduction of increasingly high speed drills for mastoid surgery has heightened the concern that cochlea damage may occur in both the operated and nonoperated ear. It has been observed clinically that this damage could be associated with frequencies above 8,000 Hz and that, to observe these changes, high-frequency audiometry should be performed. Previous studies have investigated noise transmission to the cochlea at frequencies below 4,000 Hz only. There having been, until recently, limitations to the equipment available to measure higher frequencies.. Objective: To define the characteristics of noise transmitted to the cochlea during drilling of temporal bone, specifically in the higher frequency ranges up to 20,000 Hz.. Methods: Cleaned temporal bones were fitted with 3 mutually perpendicular accelerometers, capable of measuring frequencies in the range 500 to 20,000 Hz. The system was calibrated using a Kamplex Audio Traveller AA220 pure tone audiometer, and accelerometer ...

The standard transmastoid facial recess approach has become the popular technique for cochlear implantation. Although this approach has been used for implantation in patients with common cavity malformations, in patients with this anomaly and severe abnormalities of the middle ear, this approach may be technically difficult and makes the facial nerve vulnerable to injury. Using a direct approach to the common cavity through the mastoid cavity, we have successfully performed cochlear implantation in 1 patient with a common cavity malformation. This transmastoid labyrinthotomy approach to the common cavity is an effective and simple technique for placing the electrode array. It minimizes the risk to the facial nerve and may decrease postoperative cerebrospinal fluid leaks.. ...

Otologic surgery often involves a mastoidectomy, which is the removal of a portion of the mastoid region of the temporal bone, to safely access the middle and inner ear. The surgery is challenging because many critical structures are embedded within the bone, making them difficult to see and requiring a high level of accuracy with the surgical dissection instrument, a high-speed drill. We propose to automate the mastoidectomy portion of the surgery using a compact, bone-attached robot. The system described in this paper is a milling robot with four degrees-of-freedom (DOF) that is fixed to the patient during surgery using a rigid positioning frame screwed into the surface of the bone. The target volume to be removed is manually identified by the surgeon pre-operatively in a computed tomography (CT) scan and converted to a milling path for the robot. The surgeon attaches the robot to the patient in the operating room and monitors the procedure. Several design considerations are discussed in the ...

It is possible that the most common cause of pulsatile tinnitus is sigmoid sinus diverticulum and dehiscence, which can be collectively referred to as sinus wall abnormalities or SSWA. The sigmoid sinus is a blood carrying channel on the side of the brain that receives blood from veins within the brain. The blood eventually exits through the internal jugular vein. Sigmoid sinus diverticulum refers to the formation of small sac-like pouches (diverticula) that protrude through the wall of the sigmoid sinus into the mastoid bone behind the ear. Dehiscence refers to absence of part of the bone that surrounds the sigmoid sinus in the mastoid. It is unknown whether these conditions represent different parts of one disease process or spectrum, or whether they are two distinct conditions. These abnormalities cause pressure, blood flow, and noise changes within the sigmoid sinus, which ultimately results in pulsatile tinnitus. Narrowing of the blood vessel that leads into the sigmoid sinus, known as the ...

General Discussion. The human skull is a complex part of the body. It is key in identification of sex by the size of the Mastoid Process, Supraorbital Torus, tooth size, and the squareness of the mandible amongst others; it can also be used in describing age at death by tooth wear, Cranial Suture closure and general porosity of the bone (Roberts & Manchester 2010, White & Folkens 2005, Jurmain et al 2011). A later post will detail exactly how in further detail.. It has also changed as our species, Homo Sapiens, evolved from earlier hominids. The morphology of the human skull has certainly become more gracile, and as an indicator and outcome of the agricultural revolution, it seems our mandibular size and muscle robusticity has slowly become less pronounced (Larsen 1999: 230, Jurmain et al 2011). As Larsen remarks (1999: 226), it is the influence of environment and mechanical behaviour that helps determine the morphology of the skull, alongside considered genetic factors. It is important we keep ...

We review the existence of vestibulosympathetic reflexes in humans. While several methods to activate the human vestibular apparatus have been used, galvanic vestibular stimulation (GVS) is a means of selectively modulating vestibular afferent activity via electrodes over the mastoid processes, causing robust vestibular illusions of side-to-side movement. Sinusoidal GVS (sGVS) causes partial entrainment of sympathetic outflow to muscle and skin. Modulation of muscle sympathetic nerve activity (MSNA) from vestibular inputs competes with baroreceptor inputs, with stronger temporal coupling to the vestibular stimulus being observed at frequencies remote from the cardiac frequency;
Objectives: The digastric muscle is an important landmark in head and neck surgeries. Important neurovascular structures such as the spinal accessory and hypoglossal nerves (HNs), internal jugular vein (IJV) and internal carotid artery lie deep to the posterior belly of digastric (PBD); the study relating to it deserves special mention in anatomical literature. Therefore,the present study aims to describe the PBD in relation to the essential anatomical landmarks.Materials and Methods: This study was carried out using 10 cadavers preserved in 10% formalin. The midpoint of IJV in the neck was identified as the point between the angle of the mandible and midclavicular point. The anatomical landmarks considered for measuring the parameters were tip of the mastoid process (TMP), loop of HN, midpoint of IJV, bifurcation of common carotid artery (CCA) and the midpoint of PBD.

The parapharyngeal space harbors 0.5% of all head and neck neoplasms. The surgical approach is the primary difficulty during these tumors resection once superiorly the access becomes more restricted by the progressive encroachment of the mastoid process and the angle of the mandible. Different types of mandibulotomy performed to improve the access to the parapharyngeal space are described in the literature. The aim of this work is to describe the technique used during parapharyngeal space neoplasms resection when a wider access is necessary. The technique is a pre-mental foramen mandibulotomy combined with a ramus osteotomy, which allows the mandibular body segment to be rotated completely out of the operative field. After the tumor resection the mandibular segment is reduced and its fixation is made with 2.0 and 2.4 plates and screws systems. The double mandibulotomy not only provides a wider field but also protects the inferior alveolar neurovascular bundle, which remains completely contained ...
This invention relates to a leak-proof swimming cap with sealing structure for affecting a water-tight seal around the margin of the cap.

It arises from the lower half of the nuchal ligament, from the spinous process of the seventh cervical vertebra, and from the spinous processes of the upper three or four thoracic vertebrae. The fibers of the muscle are directed upward and laterally and are inserted, under cover of the sternocleidomastoideus, into the mastoid process of the temporal bone, and into the rough surface on the occipital bone just below the lateral third of the superior nuchal line. The splenius capitis is deep to sternocleidomastoideus at the mastoid process, and to the trapezius for its lower portion. It is one of the muscles that forms the floor of the posterior triangle of the neck. The splenius capitis muscle is innervated by the posterior ramus of spinal nerves C3 and C4. ...

Giant cell reparative granuloma (GCRG) is an uncommon lesion most often affecting the jaw but also the small bones of the hands and feet. GCRG overlaps clinically and radiographically with other giant cell-rich tumors such as giant cell tumor of bone (GCTB) and aneurysmal bone cyst (ABC). In the only case of a cytogenetically investigated GCRG reported previously, a balanced translocation involving chromosomes 4 and X was found. In the present study, chromosome banding and fluorescence in situ hybridization (FISH) analyses were used to characterize the primary lesion and local recurrence of a GCRG in the thumb and skin biopsy of a 45-year-old woman. The skin showed a normal karyotype. Various forms of a dic(8;22) containing 8q, 22q, and smaller or larger parts of 8p were found in both GCRG samples. In addition, ring chromosomes, most often composed of chromosome I I material, and telomeric associations were found. The latter aberrations were more frequent in the primary lesion. Normal FISH ...

Mastoiditis is an inflammatory process of the mastoid air cells in the temporal bone. Because the mastoid is contiguous to the middle ear cleft and an extension of it, virtually all children or adults with acute otitis media (AOM) and most individuals with chronic middle ear inflammatory disease have mastoiditis.
This exhibit depicts the lateral anatomy of the skull and cervical spine. Anatomical structures include: the temporal bone, cranial sutures, zygomatic arch, temporomandibular joint (TMJ), external acoustic meatus, ethmoid bone, and mastoid process.

If the cholesteotoma regrows after this type of surgery, it can be seen by the surgeon and removed during another operation.. Intact canal wall mastoidectomy. An intact canal wall mastoidectomy is an operation where the bony wall between the ear canal and mastoid is not removed. Water can enter the ear after surgery without the risk of complications. However, the disadvantages are that it is more difficult to see the cholesteotoma during surgery and to remove it fully. This means that it may grow again. If it does, the cholesteotoma cannot be seen easily when looking down the ear canal, so early detection is usually not possible. Recurrence of cholesteotoma may not result in early symptoms, so complications may occur without warning. Due to this risk, many surgeons recommend a second operation one or two years later to check whether regrowth has occurred .. Myringoplasty. A myringoplasty is an operation to repair the eardrum. It is usually done at the same time as the mastoidectomy. A graft, ...
A cochlear implant is an electronic device that transmits electrical impulses to the brain where they are perceived as sounds both for children who are born deaf or become deaf and also deaf or severely hard of hearing adults.. The cochlear implant consists of two parts:. - the external part with a speech processor incorporating a microphone which is placed behind the ear with a transmitter coil or with a compact, single-unit audio processor that is held in place by magnets over the implanted receiver. - a surgically implanted internal part consisting of a receiver package implanted in a recess in the mastoid bone which is connected to the electrode array positioned within the cochlea.. Today the possibility of obtaining a cochlear implant in Europe is still very uneven and depends in particular on the social insurance system of the country concerned.. It should be remembered that health policy in the European Union is in the first place the responsibility of each state member.. Numerous ...
Spontaneous cerebrospinal fluid leaks of the temporal bone are uncommon conditions, but with increasing incidence in the last years. They represent the osteodural defect of the middle and posterior fossae floor with consequent communication between the subarachnoid space and the middle ear and mastoid cells, not associated with a history of trauma, chronic infections, tumors, surgery or irradiation. Physiopathogenesis is not well defined, being associated with the faulty development of the temporal bone and/or the presence of aberrant arachnoid granulations, in addition to being favored by idiopathic intracranial hypertension, obstructive sleep apnea and obesity. It has the potential for serious neurological complications, which is why surgical treatment is recommended. The main approaches involve transmastoid access and craniotomy access through the middle fossa, or a combination of both. This paper reports on a case attended at Grupo Santa Casa BH and performs a literature review and on aspects

The middle ear is an airspace located behind the eardrum that consists of two connecting compartments. The compartment directly behind the eardrum is called the tympanum and contains the three small bones of the middle ear, the hammer, anvil and stapes, that function to transfer eardrum movements to the inner ear so that you can hear. Behind the tympanum is the mastoid cavity which is a larger airspace subdivided into small air cells of unknown function. For normal hearing, it is important that the air pressure in the middle ear is similar to that of the environment so that the eardrum can move freely in response to sounds. The air pressure of the environment is not constant and is affected by changes in weather conditions (high and low pressure systems that move through the area) and by changes in elevation above sea level (the fullness in your ears that can be noticed when you ride in an elevator or in an airplane). The air pressure in the middle ear also changes because middle ear gas is ...
In patients with recurrent meningitis, one of the possible routes of infection is via an abnormal pathway connecting the CSF space with the middle ear or mastoid air cells. These patients may also have CSF rhinorrhea or CSF otorrhea, depending on the integrity of the ear drum.. The commonly recognized causes of CSF leakage into the middle ear include trauma to the temporal bone and prior surgery with subsequent temporal bone defects and chronic infection (4, 5). Spontaneous CSF fistulas from the subarachnoid space into the middle ear cavity are uncommon and may be classified into two types: those that extend to the middle ear or external canal (perilabyrinthine) and those associated with a developmental anomaly of the cochlea (translabyrinthine) (2, 6).. The more common translabyrinthine variety is nearly always associated with anacusis and a severe labyrinthine dysplasia. The involved cochlea completely lacks a modiolus and thus permits ready communication between the CSF and the perilymphatic ...
The CT examination when done showed a small epidural enhanced left petrous collection with downward extension to the superior pharyngeal mucosal space, extensive destruction of the ipsilateral petrous apex and opacification of the tympanic cavity and mastoid air cells, with mastoidal sclerosis. The MRI showed the left petrous apex lesion, which was hypointense as seen on T1-weighted images, hyperintense when seen on T2-weighted images and enhanced by using gadolinium, and also demonstrated the small infracranial extension. CT and MRI are highly sensitive in detecting petrous apex lesions. As in this case, they permit the identification of apical osteomyelitis surrounded by a phlegmon collection. When the petrous apicitis is large enough, it can injure the VI cranial nerve where it passes through the petrous apex in Dorellos canal, on its way to the orbit via the cavernous sinus. Then, the patient presents with the symptoms of Gradenigos syndrome: otitis media, deep facial pain along the ...

ERP recording and analysis. The EEG was recorded continuously from 34 scalp sites using Ag/AgCl electrodes mounted on an elastic cap (Easy Cap; Falk Minow Services, Herrsching-Breitbrunn, Germany), positioned according to the 10-20 International system (American Electroencephalographic Society, 1991) using NuAmp amplifiers (Neuroscan, El Paso, TX). The montage included six midline sites (FZ, FCZ, CZ, CPZ, PZ, and OZ) and 14 sites over each hemisphere (FP1/FP2, F7/F8, F3/F4, FT7/FT8, FC3/FC4, T7/T8, C3/C4, TP7/TP8, CP3/CP4, P7/P8, P3/P4, PO7/PO8, PO3/PO4, and O1/O2). Additional electrodes were used as ground and reference sites and for recording the electrooculogram (EOG). Recordings were referenced to the right mastoid and then re-referenced off-line to the algebraic average of the right and left mastoids. The horizontal and vertical EOGs were recorded bipolarly with electrodes placed around the eyes to measure horizontal and vertical eye movements, respectively. The signal was digitized at a ...

The primary process in DDMS is asymmetric cerebral hemisphere growth with atrophy of one side. The ipsilateral lateral ventricle and cortical sulci enlarge as a result of parenchymal volume loss. Compensatory osseous thickening is an adaptive response to the unilateral decrease of brain substance and results in ipsilateral calvarial thickening, overdevelopment of the paranasal sinuses and mastoid air cells, elevation of the petrous ridge, sphenoid wing and orbital roof and hypoplasia of the middle and anterior cranial fossae. Ipsilateral displacement of the falx attachment is a key finding of DDMS. Importantly, this distinguishes the concomitant ipsilateral midline shift as a developmental anomaly ...

The sound processor (1) vibrates with sound, transmitting these sound vibrations through the titanium abutment and implant (2) then through the bone and directly into the inner ear (3), bypassing the ear drum and bones of hearing. This direct transmission of sound brings a strong signal to the hearing nerve of the inner ear and results in marked hearing improvement.. The BAHA device was developed over 25 years ago by Dr. Tjellstrom of Sweden and approved for use in the United States approximately 10 years ago for conductive hearing loss. More recently the BAHA device has also been approved for those patients with profound nerve loss in one ear. Thousands of successful long term users of the device are enthusiastic about their improved BAHA.. The BAHA results in very marked improvement in communication ability in those with chronically draining ears, open mastoid cavities, perforations, or acquired or congenital closure of the ear canal(s) in those cases where use of conventional hearing aids or ...
If mastoiditis is suspected, your child may be admitted into the hospital for evaluation and treatment. The hospital stay can last for 5 to 7 days or more. In the hospital, your child will be given intravenous (IV) antibiotics for the infection. Your child will see an otolaryngologist. This is a doctor who specializes in treating problems of the ears, nose, and throat (ENT). The ENT doctor may need to make a tiny incision in the eardrum to allow trapped fluid to drain out. This is called a myringotomy. It relieves pressure and the fluid can be tested. The test results help the ENT doctor determine which antibiotic to give your child. If these treatments dont work, your child may need surgery to remove parts of the infected mastoid. This is called a mastoidectomy. ...

In the May 2016 issue of Plastic and Reconstructive Surgery, a paper was published entitled Classification and Algorithmic Management of Constricted Ear: A 22-Year Experience. Over 160 ears that had a lidded helix, compressed scapha and triangular fossa and an overall cuplike appearance were used as the clinical material for the study. The authors classification system uses a antihelical tubing test and a scapha-helix push test. By these two methods four types of contricted ear are identified. Type 1 constricted ears can be treated by an antihelical tubing procedure using horizontal mattress sutures placed on the backside of the ear. A type 2 constricted ear was treated by tumbling concha-cartilage flap combined with a mastoid hitch suture. In type 3 constricted ears an antihelical wrapping technique using a free floating rib cartilage graft was used. In type 4 constricted ears where a shortage of helix exists, a helical expansion technique using a rib graft and preauricular and scapha skin ...
