Retrosigmoid Resection of a Giant Left Vestibular Schwannoma in the Sitting Position
Abstract
This video presents the microsurgical resection of a giant left vestibular schwannoma in a 19-year-old woman with Turner syndrome. A gravity-assisted retrosigmoid approach in the sitting position was used. Near-total resection was achieved using bimanual dissection under continuous neurophysiological monitoring. A high-riding jugular bulb precluded drilling of the internal auditory canal, leaving minimal intracanalicular tumor. Postoperative imaging confirmed brainstem decompression. The patient developed a transient House–Brackmann grade II facial palsy, which fully resolved. Publication History Article published online: 27 February 2026 © 2026. Thieme. All rights reserved.
