title: Surgical treatment of labyrinthine fistula caused by cholesteatoma with semicircular canal occlusion.
abstract: CONCLUSIONS
  Semicircular canal occlusion after completely removing cholesteatoma matrix is a safe and effective approach for treatment of labyrinthine fistula.
  
  
  OBJECTIVE
  To investigate the safety and efficacy of semicircular canal occlusion for surgical treatment of labyrinthine fistula caused by cholesteatoma.
  
  
  METHODS
  Twenty-two patients with labyrinthine fistula who were treated surgically were enrolled in the study. All patients were treated by completely removing the cholesteatoma matrix followed by semicircular canal occlusion.
  
  
  RESULTS
  With a follow-up of at least 6 months, there was no recurrent cholesteatoma in any of the patients. Vertigo disappeared in all the patients. Most patients presented no hearing detriment and four of them demonstrated hearing improvement. No patient presented with surgery-related deafness postoperatively.
