Tympanoplasty in adhesive otitis media: A descriptive study.

OBJECTIVES/HYPOTHESIS: There is no consensus among clinicians regarding the best treatment strategy for adhesive otitis media (AdOM). It is common practice to only intervene in the presence of recurrent infections or significant conductive hearing loss. In an attempt to provide evidence regarding the efficacy and safety of surgical intervention, we have analyzed the long-term outcome of tympanoplasty for AdOM .

STUDY DESIGN: Prospective study.

METHODS: From January 2013 to April 2014, 57 patients with AdOM (60 ears) who fit our criteria for tympanoplasty were recruited and underwent tympanoplasty using tragal cartilage combined with transtympanic ventilation tube and cortical mastoidectomy. Otorrhea control, graft uptake, hearing level changes, and complications were evaluated within a 3-year period of follow-up.

RESULTS: Otorrhea was controlled in 94% of the ears. Tympanic membrane healing was achieved in all ears except one ear, which had myringitis. Overall there was significant improvement in hearing. Whereas the mean preoperative air-bone gap (ABG) was 30.4 ± 4.0 dB, postoperative mean ABG was 8.6 ± 6.9 dB at 1 year. Closure of ABG to within 20 dB was achieved in 46 ears (83.6%). One ear showed a drop in bone conduction level by 25 dB. No iatrogenic cholesteatoma was detected in any of the cases.

CONCLUSION: This study demonstrated that tympanoplasty has favorable outcomes in AdOM . Risks of iatrogenic sensorineural hearing loss or cholesteatoma formation are negligible.
