title: [The enlargement of the meatal entrance in canal-wall-down operations].
abstract: BACKGROUND
  The canal-wall-down operation may narrow the meatal entrance.
  
  
  METHODS
  By means of excision of skin from the cavum conchae and conchal cartilage an adequate-sized meatus can be created.
  
  
  RESULTS
  17 children were treated in case of cholesteatoma with canal-wall-down operation and metoplasty. The meatal entrance was sufficiently enlarged in all patients.
  
  
  CONCLUSIONS
  The presented metoplasty supplies good functional and cosmetic results.
