title: Efficacy of the 2-staged procedure in the management of cholesteatoma.
abstract: OBJECTIVE
  To demonstrate the efficacy of intact canal wall procedure coupled with a second-stage exploration for the treatment of cholesteatoma.
  
  
  METHODS
  Retrospective case study of patients with cholesteatomas treated with staged surgical extirpation. A minimum of 6 months' postoperative follow-up time was required for inclusion into the study.
  
  
  METHODS
  Tertiary academic referral center. Patients A total of 35 adult and pediatric patients, ranging from 9 to 65 years of age, who underwent 2-stage procedures for removal of cholesteatomas.
  
  
  METHODS
  Two-stage procedures, separated by 6 months, performed with posterior tympanotomy approaches.
  
  
  METHODS
  The presence or absence of cholesteatoma on second-stage look and the subsequent surgical treatment for recurrent cholesteatoma. The overall hearing results after the completion of the 2-staged procedure were calculated.
  
  
  RESULTS
  Disease was controlled in 26 (74%) of the patients. Residual and/or recurrent cholesteatomas were found in 9 (26%) of the patients during the second-stage operation. Of these patients, 5 (14% of the total group) ultimately required conversion to canal-wall-down procedure. Average hearing gain at the completion of the second-stage procedure was 9 dB.
  
  
  CONCLUSIONS
  A planned 2-stage procedure that uses the posterior tympanotomy approach for the control of cholesteatoma is an effective technique. This approach offers significant potential for hearing preservation and restoration.
