Description
Summary:Abstract Objectives  To analyze growth of residual vestibular schwannoma (VS) following incomplete tumor resection and determine the influence of residual location and size. Design  Retrospective case note and scan review. Setting  Tertiary skull base unit. Participants  Patients with residual tumor following primary surgery for medium and large unilateral growing vestibular schwanomas between 2006 and 2009. Main Outcome Measures  Location of residual VS and post-operative growth, comparing those with more (>5%) or less than 5% of tumor residual ( 5%. All positions of residual tumor can regrow, and the preoperative tumor size plays a role in this. Further data is needed to confirm if residual tumor in the fundus is less likely to grow.
