Cochlear Patency after Translabyrinthine Vestibular Schwannoma Surgery

Abstract

Objectives: To determine the temporal occurrence of fluid signal changes on T2-weighted magnetic resonance imaging (T2MRI) that occur in the cochlear lumen after translabyrinthine surgery. Study Design: Retrospective case control study. Setting: Tertiary referral neurotology center. Subjects and Methods: Seventy-one patients were identified who underwent translabyrinthine removal of a vestibular schwannoma between 2010 and 2014; of these 49 were included as they had postoperative T2 MRI at 6, 18, and 48 months available postsurgery. Magnetic resonance imaging scans were scored base on fluid signal changes within the cochlea. Results: In total, 147 magnetic resonance imaging scans were review..
