متن کاملThe Dehiscent Facial Nerve Canal
Accidental injury to the facial nerve where the bony canal defects are present may result with facial nerve dysfunction during otological surgery. Therefore, it is critical to know the incidence and the type of facial nerve dehiscences in the presence of normal development of the facial canal. The aim of this study is to review the site and the type of such bony defects in 144 patients operated...
متن کاملDuplication anomaly of the internal auditory canal.
A 45-year-old man presented with slowly progressive left-sided hearing loss of 5 years duration. Examination revealed bilateral sensorineural hearing loss, more severe on the left, with poor speech discrimination on the left. Brainstem-evoked-response audiometry demonstrated borderline prolongation of interpeak latencies and poor early wave identification on the left side. A retrocochlear lesio...
متن کاملDumbbell schwannomas of the internal auditory canal.
BACKGROUND AND PURPOSE Benign tumors of the internal auditory canal (IAC) may leave the confines of the IAC fundus and extend into inner ear structures, forming a dumbbell-shaped lesion. It is important to differentiate dumbbell lesions, which include facial and vestibulocochlear schwannomas, from simple intracanalicular schwannomas, as surgical techniques and prognostic implications are affect...
