title: Role of aerating mastoidectomy in noncholesteatomatous chronic otitis media.
abstract: OBJECTIVE
  To assess the success rate of revision tympanoplasty with aerating mastoidectomy in patients with noncholesteatomatous chronic otitis media who had failed at least one prior tympanoplasty.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  Data were analyzed from 135 patients available for clinical and audiometric studies with a minimum of 18 months' follow-up. All patients had failed at least one prior tympanoplasty and presented with: 1) a persistent tympanic membrane perforation with intermittent drainage, or 2) a wet draining ear, unresponsive to systemic antibiotic and topical management. All patients underwent 1.5-mm, high-density, bone window computed tomography (CT) scanning to assess middle ear, epitympanic, and mastoid air cell pneumatization. All patients underwent revision tympanoplasty with aerating mastoidectomy via a postauricular approach. Patient charts were reviewed for information regarding preoperative radiographic findings, mucosal and ossicular findings at the time of surgery, and success or failure of revision tympanomastoidectomy.
  
  
  RESULTS
  The tympanic membrane graft take rate for the entire group of 135 patients was 90.4% (13 grafts failed). A majority of the patients were found to have radiographic and intraoperative evidence of middle ear/mastoid disease.
  
  
  CONCLUSIONS
  For patients with noncholesteatomatous chronic otitis media who have failed prior tympanoplastic reconstruction, an aerating mastoidectomy may be indicated and may improve the success rate of the surgery.
