Patulous internal auditory canal.
OBJECTIVE To investigate a rare anomaly of the internal auditory canal known as a patulous canal and its relationship to hearing impairment. METHODS High-resolution computed tomographic scans of the temporal bones of patients who presented between August 2001 and August 2002 were reviewed.

متن کاملCadaveric Testing of Robot-Assisted Access to the Internal Auditory Canal for Vestibular Schwannoma Removal.
HYPOTHESIS An image-guided robotic system can safely perform the bulk removal of bone during the translabyrinthine approach to vestibular schwannoma (VS). BACKGROUND The translabyrinthine approach to VS removal involves extensive manual milling in the temporal bone to gain access to the internal auditory canal (IAC) for tumor resection. This bone removal is time consuming and challenging due ...
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...
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...
