Introduction Middle fossa approach has been suggested as an alternative for patients in whom other routes of electrode insertion are contraindicated. Even though there are temporal bone studies about the feasibility of introducing the cochlear implant through the middle fossa, until now, very few studies have described results when cochlear implant surgery is done through this approach. Objecti...

OBJECTIVES To report a giant cell tumor (GCT) of temporal bone and infratemporal fossa and to review the literature pertinent to the care of such patients. STUDY DESIGN Case report and review of the literature. METHODS A review of the literature was conducted using Pubmed and the key words temporal bone, GCT, infratemporal fossa, and recurrent GCT. Medical records from an index case were an...

Introduction  Pigmented villonodular synovitis (PVNS) is a benign but aggressive lesion arising from sinovia. The temporomandibular joint (TMJ) is hardly ever involved. Methods  We describe a case of PVNS arising in the left TMJ involving infratemporal fossa soft tissue and the skull base; we also present the reconstruction. Results  A 37-year-old woman had progressive mandibular swelling for 6...

Removal of an impacted maxillary third molar can be challenging for both dental clinicians and oral surgeons. Frequently encountered complications include infection, pain, swelling, root fractures, trismus, haemorrhage. In addition, unexpected displacement the may during extraction process. This case report presents a displaced to infratemporal fossa, as well removal tooth following 1 month, al...

Dandy-Walker Malformation (DWM) is a rare congenital anomaly of the posterior cranial fossa. Features DWM include hypoplasia cerebellar vermis, enlargement fossa, and cystic dilatation fourth ventricle. MRI modality to confirm diagnosis. Treatment usually symptomatic required when signs hydrocephalus develop. Rare cases asymptomatic diagnosed incidentally are reported in literature. We report c...

Objective Multiple landmarks and anatomic relationships exist to identify internal acoustic canal (IAC) in middle fossa approach for removing intracanalicular schwannomas. We attempted to identify a reproducible, practical method to quickly identify the IAC that would be applicable when an expanded middle fossa approach is required. Design Middle fossa approach was performed on 10 cadavers (21 ...

OBJECTIVE Many surgeons advocate for watertight dural reconstruction after posterior fossa surgery given the significant risk of cerebrospinal fluid (CSF) leak. Little evidence exists for posterior fossa dural reconstruction utilizing monolayer collagen matrix onlay graft in a non-watertight fashion. Our objective was to report the results of using collagen matrix in a non-watertight fashion fo...

A retrospective review was performed of patients treated for middle ear cholesteatoma with bone defects of the skull base via a combined transmastoid/middle fossa approach at the University of Tsukuba Hospital from 2006 through 2011 to determine the safety and effectiveness of a combined transmastoid/middle fossa approach for the treatment of cholesteatoma involving the middle cranial fossa. Th...

UNLABELLED The amount and direction of condylar growth, glenoid fossa displacement, and "effective" temporomandibular joint (TMJ) changes (a summation of condylar growth, glenoid fossa displacement, and condylar position changes within the fossa) were analyzed in 35 Class II, Division 1 malocclusions (23 boys and 12 girls) treated with the Herbst appliance. Lateral head films in habitual occlus...

OBJECTIVES To describe an unusual location for a common benign salivary gland neoplasm. STUDY DESIGN Case report and literature review. METHODS We describe an unusual lesion found in the infratemporal fossa on computed tomography of the facial skeleton, including the clinical presentation, workup, and surgical approach. A complete PubMed search of atypical presentations of pleomorphic adeno...
