P466: RETROLABYRINTHINE ENDOSCOPIC ASSISTED APPROACH FOR RESECTION OF ACOUSTIC NEUROMA
Lawrance Lee, MD; Arman Saeedi, MPH; Nauman F Manzoor; Virginia Commonwealth University
Vestibular schwannoma, a slow-growing benign tumor of the vestibular nerve, can cause significant morbidity if left untreated.
Classic retrosigmoid and translabyrinthine approaches risk complications associated with cerebellar retraction and craniotomy, or sacrifice hearing, respectively.
The retrolabyrinthine corridor can also be used to access the internal auditory canal and, depending on patient anatomy, this can offer an alternative hearing preservation approach.
Objective: to describe an endoscopic-assisted retrolabyrinthine approach to acoustic neuroma with complete labyrinthine preservation
