title: [Clinic feathers of cholesteatoma in children].
abstract: OBJECTIVE
  In order to identify the different feathers of cholesteatoma of the middle ear between children and adults.
  
  
  METHODS
  We investigated retrospectively 35 cases (40 ears) of cholesteatoma in the middle ear of children, as well as 20 cases (21 ears) of adults.
  
  
  RESULTS
  The results revealed that cholesteatoma in children manifested more extensive distribution of lesion as well as more serious ossicular chain damage than those in adults. A statistically significant relationship was revealed between lesion extent and ossicular chain damage. Hearing level pre-operation and post-operation were similar.
  
  
  CONCLUSIONS
  Cholesteatoma is a more extensive and aggressive disease in the pediatric age group than in adults. Most children with an extensive disease require a CWD procedure. Hearing preservation depends on the extent of the disease, pre-operation hearing level and the surgical procedure chosen.
