BACKGROUND AND PURPOSE The imaging appearance of facial nerve schwannomas (FNSs) has been described as an enhancing tubular mass (using T1-enhanced MR) within an enlarged facial nerve canal (using CT). The purpose of this study is to identify how often the FNS imaging findings conform to this description and determine whether there are underlying anatomic(More)
OBJECTIVE Superior canal dehiscence (SCD) is a recently described disorder that results from absence of bone over the superior semicircular canal. We have reviewed 30 cases of SCD found at our institution and report their presentation, workup, and response to therapy. STUDY DESIGN Retrospective chart review of all patients diagnosed with SCD from 1999 to(More)
BACKGROUND AND PURPOSE High-resolution T2-weighted fast spin-echo MR imaging provides excellent depiction of the cisternal and intracanalicular segments of the vestibulocochlear and facial nerves. Absence or reduction in caliber of the cochlear nerve (deficiency) has been described in association with congenital sensorineural hearing loss (SNHL). Depiction(More)
Anomalies of the course of the facial nerve have been reported in association with middle and inner ear malformations. Bifurcation of its intratemporal portion is a rare malformation in which focal splitting of one or more facial nerve segments occurs. We describe the CT appearance of this anomaly and discuss its possible embryology. Facial nerve(More)
OBJECTIVE The rostral middle fossa faces the temporal pole and is the endocranial anterosuperior aspect of the greater wing of the sphenoid. Standard approaches to this region, such as the subtemporal, pterional, or orbitozygomatic approaches, require significant brain retraction or manipulation of the temporalis muscle. We report an endoscopic sublabial(More)
OBJECTIVES/HYPOTHESIS Cochlear nerve stimulation using a linear array of electrodes, the cochlear implant, has become an accepted treatment for profound deafness. Major limitations of this technology are high threshold of stimulation, poor performance in a noisy background, cross-talk between electrodes, unsatisfactory channel selectivity, and variable(More)
Necrotizing fasciitis of the face is extremely rare. However, dentists should be familiar with the presentation of this condition because of the suddenness of its onset, the rapidity of its spread, the resulting drastically disfiguring morbidity and the high rate of mortality associated with it. In this paper, we describe the presentation and treatment of a(More)
OBJECTIVES To present the imaging findings and anatomical locations of a series of 88 facial nerve neuromas from two centers over a 30-year period. We describe the salient radiological features of neuromas in each anatomical location and outline the ways in which modern imaging techniques have altered our perception of this entity. STUDY DESIGN A(More)
INTRODUCTION The treatment of malignant otitis externa (MOE) with hyperbaric oxygen therapy (HBOT) remains controversial. The rarity of MOE, combined with poor access to hyperbaric facilities, explains the paucity of existing data. METHODS We retrospectively reviewed all patients with a diagnosis of MOE referred to the Prince of Wales Hospital hyperbaric(More)
