title: Canal wall-down mastoidectomy with mastoid obliteration for pediatric cholesteatoma.
abstract: CONCLUSIONS
  As cholesteatoma is widespread and erosive, it should be cleared away thoroughly, to keep a dry ear and conserve maximum hearing ability in children. Canal wall-down mastoidectomy with mastoid and epitympanum obliteration is a good choice for treatment of cholesteatoma in children.
  
  
  OBJECTIVE
  To investigate canal wall-down mastoidectomy with mastoid and epitympanum obliteration for the treatment of cholesteatoma in children.
  
  
  METHODS
  A retrospective analysis of all cases of pediatric middle ear cholesteatoma in children aged 5-12 years between 1999 and 2006 was conducted in Anhui Provincial Hospital. The follow-up information was completed. Forty-five patients (48 ears) were treated with canal wall-down mastoidectomy with mastoid and epitympanum obliteration and followed up for 2-5 years (mean 3.1 years).
  
  
  RESULTS
  The recurrence rate and residual rate were 4.16% and 0%, respectively. All ears were dry within 8-10 weeks. Aural discharge was detected in two cases and controlled with antibiotic ear drops without complications. The dry ear rate was 95.8%. The air-bone gap closure had a mean of 17.2 +/- 2 dB. No obvious complication occurred after operations.
