title: Cosmetic reconstruction after mastoidectomy for the transpetrosal-presigmoid approach: technical note.
abstract: OBJECTIVE
  We describe the technique of cosmetic reconstruction after mastoidectomy in the transpetrosal-presigmoid approach for petroclival lesions.
  
  
  METHODS
  This technique involves raising a single temporo-occipital bone flap and cosmetic mastoidectomy, removing the mastoid bone fragments (by means of a rongeur instead of an air drill) for later reconstruction. Replacement of the bone fragments mixed with fibrin glue enables tamponade against the dura to be achieved without a fat graft.
  
  
  RESULTS
  Computed tomographic scans and plain cranial films taken a few years later showed successful reconstruction of the mastoid bone with a good appearance of the retromastoid area in seven patients who underwent this procedure. The only complication was infection in one patient from cerebrospinal fluid leakage from the wound.
  
  
  CONCLUSIONS
  We have developed a simple and easy technique of cosmetic reconstruction after the transpetrosal-presigmoid approach.
