title: Postoperative results for cholesteatoma in children.
abstract: OBJECTIVE
  to review the postoperative results for cholesteatoma in children.
  
  
  METHODS
  32 ears with acquired cholesteatoma in children operated on by a single surgeon between 1987 and 1995 and followed up more than 2 years. The mean follow-up period was 5.4 years.
  
  
  RESULTS
  a one-stage operation was performed in seven ears (21.9%) and preplanned stage operation in 25 ears (78.1%). In the first operation, closed tympanoplasty was performed in 31 ears (96.9%) and open tymapanoplasty in one ear (3.1%). During the second stage operation, residual cholesteatoma was found in 16 ears (64.0%). Recurrent cholesteatoma was detected in 19.4% of ears treated with closed tympanoplasty. The mean postoperative air conduction hearing level was within 20 dB in 12.5%, 30 dB in 40.6% and 40 dB in 78.1%. The hearing results of type III tympanoplasty was better than those of type IV tympanoplasty.
  
  
  CONCLUSIONS
  preplanned stage tympanoplasty is safer because of the high risk of recurrent and residual cholesteatoma. Surgical methods should be selected flexibly in individual cases depending upon cavity size, eustachian tube function and hearing level. Cholesteatoma in children should be operated on while stapes is present.
