title: [External auditory canal reconstruction and mastoid cavity obliteration with composite multifractured osteoperiosteal flap: a preliminary study].
abstract: OBJECTIVE
  Open cavity mastoidectomy techniques cause some cavity problems. We used inferior pedicled composite multifractured osteoperiosteal flap, which is our original surgical approach to obliterate the mastoid cavity, reconstruct the external auditory canal (EAC), and to prevent open cavity problems.
  
  
  METHODS
  Composite multifractured osteoperiosteal flap was used to obliterate the mastoid cavity and reconstruct the EAC in four patients (2 females, 2 males; mean age 34; range 31 to 38 years) who previously underwent radical mastoidectomy to treat chronic otitis media with cholesteatoma. Small meatoplasty was applied in all the patients to relive their esthetical concerns. The patients were followed-up for two years.
  
  
  RESULTS
  The epithelization of the new EAC was complete at the end of the second month. Cholesteatoma, granulation, or recurrence of osteitis did not occur in any of the patients. We detected new bone formation filling the mastoid cavity on postoperative temporal bone CT images.
  
  
  CONCLUSIONS
  An almost natural EAC was obtained due to neo-osteogenesis that developed behind the composite multifractured osteoperiosteal flap.
