Is Longer Surgery More Dangerous? Operative Duration Not Associated With Complications After Vestibular Schwannoma Resection

Objective: To examine the association between operative duration and complications after vestibular schwannoma (VS) surgery. Study Design: Retrospective chart review. Setting: Tertiary referral center. Patients: One hundred forty-eight patients undergoing vestibular schwannoma resection in a single institution. Intervention: Vestibular schwannoma resection. Main Outcome Measures: Operative duration, surgical approach, tumor size, and postoperative complications. Results: Forty-one patients underwent middle cranial fossa (MCF) approach, 46 underwent translabyrinthine (TL) approach, and 61 underwent retrosigmoid (RS) approach. The mean operative duration overall was 407 minutes (MCF—339 min, TL—450 min, RS 420 min). When controlling for tumor size, there was no difference in procedure duration by approach (OR 0.92, CI 0.82–1.02, p=0.11). When controlling for approach, there was a significant increase in procedure duration by tumor size (OR 1.36, CI 1.23–1.50, p
