Nerve of origin, tumor size, hearing preservation, and facial nerve outcomes in 359 vestibular schwannoma resections at a tertiary care academic center.

摘要: Objective: To determine nerve of origin, tumor size, hearing preservation rates, and facial outcomes in a retrospective cohort study patients undergoing translabyrinthine (TL), middle cranial fossa (MCF), retrosigmoid/suboccipital (SO) approaches to vestibular schwannomas (VS). Study Design: Retrospective. Methods: Chart review. Results: Patient charts from 231 TL, 70 MCF, 53 SO, 5 combined TL/SO procedures for VS were evaluated 356 patients. The inferior (IVN) was the origin 84 359 cases (23.3%), while superior (SVN) 36 (10%). In 239 (66.6%), not identified. Forty surgery had results data available review. Functional ( 50% speech discrimination) preserved 10 15 (75%) with SVN tumors, only 7 25 (28%) IVN tumors retained functional hearing. Facial recorded simultaneously 109 Seventy-one 74 (95%) achieved House-Brackmann (HB) grade I–III, 35 (100%) HB I–III function. Looking at size versus preservation, 22 49 (45%) <1-cm 4 20 (20%) 1- 1.5-cm tumors. For all documented function, 96% 94% 88% TL procedures. Conclusions: Our indicated that twice as common did affect but impact rates. Patients 90% achieving 1 3 function final follow-up.
