Endoscope‐assisted resection of intravestibular Schwannoma: A video case report

Intravestibular schwannomas are a rare cause of unilateral sensorineural hearing loss. Management of these tumors involves translabyrinthine resection, for which complete visualization around the angles of the vestibule may be limited under an operating microscope. We present the first reported case of an endoscope‐assisted resection of an intravestibular schwannoma, along with the operative video recording. Using additional information gained from endoscopic examination of the tumor and its resection site, we also propose a mechanism by which this patient's intravestibular schwannoma caused hearing loss. Use of the endoscope in resection of intravestibular schwannomas may have advantages over the traditional operating microscope in improving visualization of the narrow and angled vestibule, confirming the integrity of surrounding structures, and ensuring complete tumor removal.
