title: [Revision surgery for chronic otitis media: evaluation of indications and results].
abstract: OBJECTIVE
  In patients who underwent primary and revision surgery for chronic otitis media, the types of revision surgery, most frequently observed regions of cholesteatoma, hearing results and the status of graft membrane were evaluated.
  
  
  METHODS
  Forty-three of 495 patients (21 males, 22 females; mean age 38.4+/-15.2 years; range 15 to 76 years) with chronic otitis media who underwent revision surgery in our clinic between May 2003 and March 2009 were evaluated retrospectively. Indications for revision surgery were recurrence of the disease in 32 patients (74.4%) and reconstruction of hearing in 11 patients (25.6%). Forty patients (93.0%) underwent revision surgery once and three patients (7.0%) underwent revision twice. Over an average of 3.2 (range 1 to 6) years follow-up after primary and revision surgery, the types of revision surgery, the most frequently observed regions of cholesteatoma, hearing results and the status of graft membrane were assessed.
  
  
  RESULTS
  Recurrence of cholesteatoma in revision surgery was seen in 28 patients (65.1%). Out of 27 patients, 23 patients (85.1%) showed intact graft membranes and four patients (14.8%) showed perforated graft membranes.
  
  
  CONCLUSIONS
  In revision surgery, the first goal is to eliminate the disease. The management of chronic otitis media with cholesteatoma is surgery. Because of high postoperative recurrence rates, long-term follow-up is necessary.
