OBJECTIVES: Bilateral tympanic membrane perforation closure is usually performed by otosurgeons in two sittings. However, in this study, transperforation myringoplasty was performed alongside contralateral tympanoplasty in a single sitting. The effectiveness of transperforation myringoplasty procedure and the benefits of single sitting bilateral surgery were evaluated.METHODS: A prospective study of 50 selected patients with mucosal-type bilateral chronic otitis media was conducted. All patients underwent transperforation myringoplasty on the side that met the inclusion criteria and tympanoplasty on the contralateral side. Graft uptake and hearing improvement were evaluated after 6 months.RESULTS: At the 6-month follow up, the graft uptake rate was 82 per cent, the hearing gain was 11.5 dB and the air-bone gap gain was 11.6 dB.CONCLUSION: This procedure offers perforation closure in a single sitting to patients with bilateral chronic otitis media who meet the inclusion criteria.
