Revision Surgery for Residual or Recurrent Vestibular Schwannoma

Abstract

Most residual tumors after primary surgery are successfully managed with watch and rescan. Tumor fragment size is the greatest determinant of revision treatment. After revision surgery, tumor regrowth is much less predictable. Revision surgery is usually considerably more difficult than primary surgery, with a higher complication rate, particularly with regard to the facial nerve. Changing the approach for revision surgery may confer an advantage to facial nerve function.
