Management of traumatic dislocation of the mandibular condyle into the middle cranial fossa. (1/44)

Dislocation of the mandibular condyle into the middle cranial fossa is a rare complication of facial trauma that can have neurological and life-threatening implications. This article discusses the anatomic features that predispose patients to this type of injury, as well as the clinical features and mechanism of injury for this rare type of condylar deformity, to help practitioners recognize this easily overlooked injury and avoid disastrous complications. The article summarizes previously published case reports of this rare complication of condylar trauma and presents a case for which initial diagnosis and a management protocol are described.  (+info)

Orbit deformities in craniofacial neurofibromatosis type 1. (2/44)

BACKGROUND AND PURPOSE: The possible relationship of orbit deformities in neurofibromatosis type 1 (NF1) to plexiform neurofibromas (PNFs) have not been fully elucidated. Our purpose was to review orbital changes in patients with craniofacial NF1. METHODS: We retrospectively reviewed CT and MR imaging abnormalities of the orbit in 31 patients (18 male, 13 female; mean age, 14 years; age range 1-40 years) with craniofacial NF1. RESULTS: Orbital abnormalities were documented in 24 patients. Six had optic nerve gliomas with enlarged optic canals. Twenty had PNFs in the orbit or contiguous to the anterior skull. The posterior orbit was distorted by encroachment from an expanded middle cranial fossa in 13 patients, and 18 had enlargement of the orbital rim. Other changes included focal decalcification or remodeling of orbital walls adjacent to PNFs in 18 patients and enlargement of cranial foramina resulting from tumor infiltration of sensory nerves in 16. These orbital deformities were sometimes progressive and always associated with orbital infiltration by PNFs. CONCLUSION: In our patients with craniofacial neurofibromatosis, bony orbital deformity occurred frequently and always with an optic nerve glioma or orbital PNF. PNFs were associated with orbital-bone changes in four patterns: expansion of the middle cranial fossa into the posterior orbit, enlargement of the orbital rim, bone erosion and decalcification by contiguous tumor, and enlargement of the cranial foramina. Orbital changes support the concept of secondary dysplasia, in which interaction of PNFs with the developing skull is a major component of the multifaceted craniofacial changes possible with NF1.  (+info)

The sphenoparietal sinus of breschet: does it exist? An anatomic study. (3/44)

BACKGROUND AND PURPOSE: The termination of the superficial middle cerebral vein is classically assimilated to the sphenoid portion of the sphenoparietal sinus. This notion has, however, been challenged in a sometimes confusing literature. The purpose of the present study was to evaluate the actual anatomic relationship existing between the sphenoparietal sinus and the superficial middle cerebral vein. METHODS: The cranial venous system of 15 nonfixed human specimens was evaluated by the corrosion cast technique (12 cases) and by classic anatomic dissection (three cases). Angiographic correlation was provided by use of the digital subtraction technique. RESULTS: The parietal portion of the sphenoparietal sinus was found to correspond to the parietal portion of the anterior branch of the middle meningeal veins. The sphenoid portion of the sphenoparietal sinus was found to be an independent venous sinus coursing under the lesser sphenoid wing, the sinus of the lesser sphenoid wing, which was connected medially to the cavernous sinus and laterally to the anterior middle meningeal veins. The superficial middle cerebral vein drained into a paracavernous sinus, a laterocavernous sinus, or a cavernous sinus but was never connected to the sphenoparietal sinus. All these venous structures were demonstrated angiographically. CONCLUSION: The sphenoparietal sinus corresponds to the artificial combination of two venous structures, the parietal portion of the anterior branch of the middle meningeal veins and a dural channel located under the lesser sphenoid wing, the sinus of the lesser sphenoid wing. The classic notion that the superficial middle cerebral vein drains into or is partially equivalent to the sphenoparietal sinus is erroneous. Our study showed these structures to be independent of each other; we found no instance in which the superficial middle cerebral vein was connected to the anterior branch of the middle meningeal veins or the sinus of the lesser sphenoid wing. The clinical implications of these anatomic findings are discussed in relation to dural arteriovenous fistulas in the region of the lesser sphenoid wing.  (+info)

MR imaging of orbital inflammatory pseudotumors with extraorbital extension. (4/44)

OBJECTIVE: To demonstrate a variety of MR imaging findings of orbital inflammatory pseudotumors with extraorbital extension. MATERIALS AND METHODS: We retrospectively reviewed the MR features of five patients, who were diagnosed clinically and radiologically as having an orbital inflammatory pseudotumor with extraorbital extension. RESULTS: The types of orbital pseudotumors were a mass in the orbital apex (n = 3), diffuse form (n = 2), and myositis (n = 1). The extraorbital extension of the orbital pseudotumor passed through the superior orbital fissure in all cases, through the inferior orbital fissure in two cases, and through the optic canal in one case. The orbital lesions extended into the following areas: the cavernous sinus (n = 4), the middle cranial fossa (n = 4), Meckel's cave (n = 2), the petrous apex (n = 2), the clivus (n = 2), the pterygopalatine fossa and infratemporal fossa (n = 2), the foramen rotundum (n = 1), the paranasal sinus (n = 1), and the infraorbital foramen (n = 1). On MR imaging, the lesions appeared as an isosignal intensity with gray matter on the T1-weighted images, as a low signal intensity on the T2-weighted images and showed a marked enhancement on the post-gadoliniumdiethylene triamine pentaacetic acid (post-Gd-DTPA) T1-sequences. The symptoms of all of the patients improved when they were given high doses of steroids. Three of the five patients experienced a recurrence. CONCLUSION: MR imaging is useful for demonstrating the presence of a variety of extraorbital extensions of orbital inflammatory pseudotumors.  (+info)

Rapidly growing microcystic meningioma of the middle fossa floor. Case report. (5/44)

A 74-year-old woman presented with a microcystic meningioma which manifested as mental disturbance. A rapidly growing tumor in the left middle fossa had not been detected by examination 10 months before. The tumor was remarkably enhanced by contrast medium on both computed tomography and magnetic resonance imaging and was associated with massive perifocal edema. Cerebral angiography revealed that the tumor was mainly fed by the left middle meningeal artery, which was embolized preoperatively. The tumor was completely removed and no postoperative adjuvant therapy was administered. The histological diagnosis was microcystic meningioma with many mitotic figures and a MIB-1 labeling index of 12.8%. Four months later, the tumor recurred and invaded the paranasal sinus. Focal irradiation successfully controlled further regrowth. This case suggests that microcystic meningioma may have aggressive features, and close observation is necessary even after gross total removal.  (+info)

Synovial chondromatosis of the temporomandibular joint with extension to the middle cranial fossa. (6/44)

A rare case of synovial chondromatosis with extension to the middle cranial fossa is reported. Synovial chondromatosis, a benign disorder characterized by multiple cartilaginous, free-floating nodules that originate from the synovial membrane is not exclusive to the temporomandibular joint (TMJ). This condition is commonly seen in the axial skeleton and can involve multiple joints. In this case, synovial chondromatosis of the TMJ led to complete bony erosion of the glenoid fossa extending into the middle cranial fossa. Although plain radiographs showed the involvement of the joint, Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) provided more detailed information about the lesion in all three dimensions. This case demonstrates the value of CT and MRI in both the diagnosis and treatment planning. A review of previously reported cases of synovial chondromatosis with cranial extensions is included.  (+info)

Assessment of the anatomical relationship between the arcuate eminence and superior semicircular canal by computed tomography. (7/44)

The anatomical relationship between the arcuate eminence (AE) and the superior semicircular canal (SSC) was examined by computed tomography (CT) in 52 petrous bones of 26 patients. After acquiring volume data by multidetector CT, 1-mm thick oblique bone window images perpendicular to the SSC were obtained from the axial images. The distances between the AE and the SSC, and the SSC and the superior surface of the petrous bone were measured. The AE corresponded exactly with the SSC in only 2/52 petrous bones, and corresponded well in 7/52. The AE was lateral to the SSC in 25/52 cases, medial to the SSC in 6/52 cases, intersected in 3/52 cases, and was indiscernible in 9/52 cases. The distance between the SSC and the petrous surface was 0 mm in 45/52 petrous bones, 1 mm in 5/52, 2 mm in 1/52, and 3 mm in 1/52. The SSC typically does not correspond exactly with the AE, and is generally located just under the surface of the petrous bone. Planning of the middle cranial fossa approach requires location of the SSC by CT.  (+info)

Dura-based giant intracranial schwannoma in the middle fossa. (8/44)

A 49-year-old female presented with a rare giant schwannoma arising from the dura mater of the middle fossa manifesting as loss of left visual acuity. Magnetic resonance imaging revealed a heterogeneously enhanced giant mass in the left middle fossa. Surgery via the transsylvian approach confirmed the origin of the tumor between the left internal carotid artery and the trigeminal nerve in the lateral wall of the cavernous sinus. Elongated abducens nerve was confirmed, but no tumor adhesion to the abducens nerve was found. The tumor was closely attached to the dura mater of the middle fossa and the lateral wall of the cavernous sinus. The histological diagnosis was schwannoma. Both left oculomotor and abducens nerve pareses occurred immediately after the operation but gradually resolved over 3 months. The operative findings indicated that this schwannoma may have arisen from the meningeal branch of the trigeminal nerve in the dura mater of the middle fossa.  (+info)

The extradural middle fossa approach (EMFA) is an anterior petrosectomy useful for accessing lesions of petroclival and cavernous sinus regions. It may be included in combined petrosal approach and extended in the anterolateral transcavernous approach. To facilitate the first attempts with this relatively uncommon approach, during dissections of human cadaveric injected heads and isolated temporal bones, we developed a simple learning method useful for localizing all anatomical structures. Technically, EMFA is a demanding interdural dissection, that provides a wide exposure of an extradural corridor between the middle meningeal artery, 5th cranial nerve, gasserian ganglion, 7th cranial nerve, geniculate ganglion, and 8th cranial nerve, internal carotid artery (C5-C6 tract and the GSPN above), arcuate eminence, cochlea, petrous apex, and petro-clival junction. Its major advantages are that it offers extradural dissection, limits the temporal lobe retraction, and avoids the transposition of

MR studies in eight patients with extraaxial arachnoid cysts in the middle cranial fossa were reviewed in order to identify any associated structural defect in the ipsilateral temporal lobe. The study was prompted by the original theory that agenesis of the temporal lobe is the primary factor in the development of these cysts. Authors of subsequent studies proposed that the cysts are a consequence of embryological malformation of the meninges only and that the adjacent temporal lobe is compressed. Our findings suggest that middle cranial fossa cysts are associated with temporal lobe hypogenesis, and also that compression of the temporal lobe is an infrequent accompaniment. ...
The sensory & postganglionic sympathetic nerves that innervate the dental pulp originate in the trigeminal & superior cervical ganglion & enter the teeth through the apical foramen. From the neural receptor in the pulp, the central process of a trigeminal sensory neuron traverses the trigeminal ganglion located in the floor of the middle cranial fossa. The central process then synapses on a second-order neuron located in the subnucleus caudalis of the brainstem trigeminal complex. ...

Arachnoid cysts (ACs), particularly suprasellar cysts, cause a wide spectrum of endocrine disorders. Herein, we report two patients diagnosed with an extensive AC in the middle cranial fossa while being investigated for etiologies of precocious puberty and short stature. One of them required surgery due to his pubertal disorders associated with compression effects of cyst. After surgery, his puberty progression was regressed within one year. On the other hand, surgery was not planned for the second patient considering of his cranial imaging findings and the extremely low incidence of growth hormone (GH) deficiency caused by middle fossa AC (MFAC). We started treatment with recombinant human GH and no complication was found during treatment follow-up. Endocrine disorders associated with MFACs are extremely rare. By presenting with these two cases, we aimed to remain our fellow physcians that ACs can be possibly cause of endocrine disorders. Clinicians should be careful evaluating endocrine ...
The compartment containing the anterior extremities and half the inferior surface of the temporal lobes (TEMPORAL LOBE) of the cerebral hemispheres. Lying posterior and inferior to the anterior cranial fossa (CRANIAL FOSSA, ANTERIOR), it is formed by part of the TEMPORAL BONE and SPHENOID BONE. It is separated from the posterior cranial fossa (CRANIAL FOSSA, POSTERIOR) by crests formed by the superior borders of the petrous parts of the temporal bones[MESH]. The middle fossa, deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior fossa by the clivus and the petrous crest. It is bounded in front by the posterior margins of the lesser wings of the sphenoid bone, the anterior clinoid processes, and the ridge forming the anterior margin of the chiasmatic groove; behind, by the superior angles of the petrous portions of the temporal bones and the dorsum sellC&; laterally by the temporal squamC&, sphenoidal angles ...
The Skull Base, upon which the Brains undersurface rests, has three main regions. The Anterior (front) Cranial Fossa is the region located above the eyes and includes structures such as: the Olfactory Bulbs, the Nasal Cavity, and Cranial Nerves (1 & 2 and sections of 3, 4 & 6) that control vision, as well as movement of the eyeballs. The Middle Cranial Fossa is the region containing the dense, boney Petrous Ridge, and houses the Internal Carotid Artery, along with sections of the Cranial Nerves (5 & 7) that control chewing and facial sensation. The Middle Cranial Fossa also contains the Cavernous Sinus, an extremely difficult structure from which to remove tumors. The Posterior (back) Cranial Fossa is where the Internal Auditory Canal (IAC) and the Cranial Nerves (7 & 8) responsible for hearing, facial expression and balance are located; the Jugular Vein also passes through this region. Of the 24 highly specialized Cranial Nerves, which control many vital functions of our head and neck, 18 ...

This report is the first clinical description of the endoscopic extradural supraorbital approach to the temporal pole. Temporal pole exposure by craniotomy needs wide elevation of the temporal muscle and broad removal of the lateral bone of the middle cranial fossa, resulting in temporal muscle atrophy, disturbed mastication, and poor cosmetic results. Furthermore, the lateral trajectory from the frontotemporal craniotomy does not satisfactorily expose the temporal pole. In contrast, our previous anatomical studies regarding the endoscopic extradural supraorbital approach demonstrated excellent visualization of the middle cranial fossa and temporal pole through the supraorbital keyhole, and the approach eliminated temporal muscle elevation and craniotomy.15,18,19 Therefore, mastication discomfort was avoided even with temporal pole surgery. The trajectory from the anterior direction was optimal to visualize the temporal pole, and it minimized the corticotomy on the temporal pole. A dural ...

A 44-year-old female presented with Duret hemorrhage due to transtentorial herniation by extradural hematoma as a complication after craniotomy for treatment of spontaneous middle cranial fossa cerebrospinal fluid leakage through the oval window. Brain computed tomography revealed linear hemorrhage in the midbrain and the rostral pons. She awoke after 2 weeks in a coma, despite showing ocular bobbing and bilateral intranuclear ophthalmoplegia. She was discharged from the hospital with minimal neurological defects. Duret hemorrhage is usually fatal, but this case shows that early surgical decompression is the most important factor to avoid the worst sequelae.
The blastema covers almost all of the lateral surface of the cartilaginous skull. A small part of the occipital cartilage, including the transverse process, part of the squama and occipital neural arch, part of the orbital wing of the sphenoid, and part of the lateral surface of the nasal capsule, are uncovered (figs. 9 and 15). Into the blastema covering the squamal cartilage, rather than into the cartilage itself, are inserted the various occipital muscles (figs. 14 and 15). The blastema covering the squama and the lateral surface of the otic capsule probably fases later with the perichondrium, but at this stage it seems to be continuous with the rest of the blastemal wall which later gives rise to membrane bones. It is in the sphenoidal and frontal regions that the blastema greatly predominates over the cartilage.

A small part of the occipital cartilage, including the transverse process, part of the squama and occipital neural arch, part of the orbital wing of the sphenoid, and part of the lateral surface of the nasal capsule, are uncovered (figs. 9 and 15). Into the blastema covering the squamal cartilage, rather than into the cartilage itself, are inserted the various occipital muscles (figs. 14 and 15). The blastema covering the squama and the lateral surface of the otic capsule probably fases later with the perichondrium, but at this stage it seems to be continuous with the rest of the blastemal wall which later gives rise to membrane bones. It is in the sphenoidal and frontal regions that the blastema greatly predominates over the cartilage. All of the lateral wall of the middle cranial fossa consists of blastema and the greater part of the floor (as well as all of the lateral wall of the anterior fossa) is likewise ...

Idiopathic orbital inflammatory (IOI) disease, or orbital pseudotumor, refers to a marginated mass-like enhancing soft tissue involving any area of the orbit. It is the most common painful orbital mass in the adult population, and is associated with proptosis, cranial nerve palsy (Tolosa-Hunt syndrome), uveitis, and retinal detachment. Idiopathic orbital inflammatory syndrome, also known as orbital pseudotumor, was first described by Gleason in 1903 and by Busse and Hochhmein. It was then characterized as a distinct entity in 1905 by Birch-Hirschfeld. It is a benign, nongranulomatous orbital inflammatory process characterized by extraocular orbital and adnexal inflammation with no known local or systemic cause. Its diagnosis is of exclusion once neoplasm, primary infection and systemic disorders have been ruled-out. Once diagnosed, it is characterized by its chronicity, anatomic location or histologic subtype. Idiopathic orbital inflammation has a varied clinical presentation depending on the ...

The lesser petrosal nerve (also known as the small superficial petrosal nerve) is the General visceral efferent (GVE) component of the glossopharyngeal nerve (CN IX), carrying parasympathetic pre-ganglionic fibers from the tympanic plexus to the parotid gland. It synapses in the Otic ganglion, from where the post-ganglionic fibers emerge. After arising in the tympanic plexus, the lesser petrosal nerve passes forward and then through the hiatus for lesser petrosal nerve on the anterior surface of the petrous part of the temporal bone into the middle cranial fossa. It travels across the floor of the middle cranial fossa, then exits the skull via foramen ovale to reach the infratemporal fossa. The fibres synapse in the otic ganglion, and post-ganglionic fibres then travel briefly with the auriculotemporal nerve (a branch of V3) before entering the body of the parotid gland. The lesser petrosal nerve will distribute its parasympathetic post-ganglionic (GVE) fibers to the parotid gland via the ...
The anterior division of the middle meningeal artery is most commonly involved.. Foramen spinosum, located in the middle cranial fossa, transmits the middle meningeal artery from the infratemporal fossa into the cranial cavity. The artery runs forward and laterally in a groove on upper surface of squamous part of temporal bone and the greater wing of sphenoid. After a short distance, the artery divides into anterior and posterior divisions. The anterior branch passes forward and upward to the anteroinferior angle of the parietal bone. Here the bone is deeply grooved by the artery for a short distance and is the site of damage after a blow. Artery then runs backwards and upwards on the parietal bone.. ...

Visual impairment Almost all Arachnoid Cysts occur in relation to an arachnoid cistern. The most common locations are the middle cranial fossa (near the temporal lobe) and suprasellar (near the third ventricle). However, cysts may be found anywhere within the intracranial compartment, including the posterior cranial fossa.. Routine evaluation with CT or MRI scan is usually satisfactory. CT scans usually show a smooth bordered cystic mass composed of a density similar to cerebrospinal fluid. There is no enhancement with contrast administration. Expansion of the nearby bone by remodeling is usually seen, confirming their chronic nature. TREATMENT. Arachnoid cysts that do not cause significant mass effect or symptoms, regardless of their size and location, generally do not require treatment. If there is significant or severe mass effect on surrounding structures, or if there are symptoms, then surgical treatment is recommended. The following table summarizes the treatment options:. ...
OBJECTIVES: To describe a unique case of bilateral dehiscence of the malleus and incus heads into the middle fossa making contact with the temporal lobes, along with its clinical implications. METHODS: An analysis of a patient case and review of pertinent literature were performed. RESULTS: A patient with a history of right-sided mastoidectomy for cholesteatoma was evaluated for persistent conductive hearing loss. On computed tomography (CT) and magnetic resonance imaging (MRI), the patient had a complete dehiscence of the tegmen tympani on the right, with ossicular heads being located above the floor of the middle cranial fossa ...
Anterior division. The V3 divides into the anterior smaller and the posterior larger divisions in the infratemporal fossa. The average distance of the undivided trunk from the foramen ovale to the bifurcation of the V3 was approximately 7.7 mm (range, 5-12 mm) (Vrionis et al., 1996). The smaller anterior division gives rise to the sensory buccal nerve and the motor branches: masseteric nerve, deep temporal nerves, and nerve to the lateral pterygoid muscle. This division passes in the horizontal plane just below the pericranium of the infratemporal surface of the middle cranial fossa (Fig. 10A).. Buccal nerve. The sensory buccal nerve passes anterolaterally between the two heads of the lateral pterygoid, below the inferior portion of the temporal muscle, and deep to the mandible and the masseter muscle (Figs. 10A, 10B, and 11A). Its course is directed between the coronoid process and tuberosity of the maxilla. It emerges from the undersurface of the ramus of the mandible and the anterior border ...

The pterygopalatine fossa (PPF), is an important small anatomic space which communicate the middle cranial fossa, orbital, nasal and oral cavities, pharynx, foramen lacerum and the infratemporal fossa. Represents a major pathway of spread of malignancy and infection in the deep face. It is a pyramidal space with an upper base , located down the orbital apex. The bony structure which delimited the PPF are: - Anterior wall: Maxillary tuberosity. - Posterior wall: the anterior face of the pterygoid apophysis. - Medial wall: vertical lamina of the palatine. - Lateral wall: free. - Superior wall: great wing of the sphenoid. - Inferior wall: is represented by the apex of the pyramid, shaped by the union of the maxillary tuberosity and the pterygoid apophysis. The PPF has 8 communications in form of orifices or osseous ducts. - Anterosuperiorly: communicates with the orbit through the inferior orbital fissure. - Posterosuperiorly: Foramen rotundum and Vidian canal communicates with the middle cranial ...

Arachnoid Cyst. Arachnoid cysts are CSF-containing cysts that are found in the middle fossa, posterior fossa, suprasellar cistern, or near the vertex. They are benign but slowly grow as they accumulate fluid, compressing normal brain structures. Remodeling of the adjacent skull is an important clue for a benign expansile process. Arachnoid cysts are smoothly marginated and homogeneous. They are not calcified and do not enhance. The multiplanar capability of MR is particularly helpful in establishing the exact location, and the diagnosis is supported by the cyst fluid being isointense with CSF on all pulse sequences. ...
