title: Subjective visual vertical in patients with ear surgery.
abstract: CONCLUSIONS
  Dysequilibrium is one of the most important side effects of ear surgery. The subjective visual vertical can be used as a good indicator for the evaluation of otolithic function in patients with ear surgery.
  
  
  OBJECTIVE
  To investigate the influence of various types of ear surgery on the otolithic organs.
  
  
  METHODS
  Seventy-one patients underwent ear surgery. Subjective visual vertical (SVV) test was performed before and after ear surgery. We investigated the directional changes of SVV before and after the ear surgery.
  
  
  RESULTS
  The postoperative SVV of two patients who underwent translabyrinthine removal of vestibular schwannoma shifted toward the operated side, but following other surgical procedures the SVV tended to shift toward the healthy side.
