title: Cavum major tympano-ossiculoplasty.
abstract: OBJECTIVE
  To evaluate the success of tympano-ossiculoplasty in patients with previous canal wall down mastoidectomy.
  
  
  METHODS
  A retrospective review of 79 patients who underwent cavum major tympano-ossiculoplasty from a total of 1,910 tympanomastoidectomies from 1976 to 1998.
  
  
  METHODS
  The results of air-bone gap closure, surgical findings, and revision surgery are presented.
  
  
  RESULTS
  In 63% of patients, the air-bone gap closed to within 20 dB with a mean gain of 14.7 dB.
  
  
  CONCLUSIONS
  A significant percentage of patients will gain substantial improvement in their hearing after cavum major tympano-ossiculoplasty with minimal risk.
