title: Outcome of residual cholesteatoma and hearing in mastoid surgery.
abstract: OBJECTIVE
  To review 12 years of the senior author's experience with mastoid surgery for cholesteatoma.
  
  
  METHODS
  Retrospective review.
  
  
  METHODS
  Northwestern University Medical School.
  
  
  METHODS
  Available records included 97 mastoid procedures for cholesteatoma: 54 with intact canal-wall and 43 canal-wall-down.
  
  
  METHODS
  Residual cholesteatoma, pure-tone audiometry, and speech audiometry were compared for both groups.
  
  
  RESULTS
  Residual disease rate was 11 of 54 (20%) for intact canal-wall procedures and 2 of 43 (5%) for canal-wall-down procedures. Average follow-up was 2 years. Hearing was preserved postoperatively, and neither procedure demonstrated clear superiority in this regard.
  
  
  CONCLUSIONS
  While canal-wall-down mastoidectomy provides a lower residual disease rate with equal hearing outcome, the role of intact wall mastoidectomy remains a viable choice in certain clinical situations.
