Objectives: To determine the influence of posterior fossa dimensions on surgical outcomes after vestibular schwannoma management. Study Design: Retrospective chart review. Setting: Tertiary care academic medical center. Patients: Patients with sporadic vestibular schwannomas who underwent surgical resection via retrosigmoid or translabyrinthine techniques.
