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.
STUDY DESIGN: 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.
CONCLUSION: 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.
