Outcome of Bilateral Myringoplasty in Dry Central Perforation- An Appraisal

Abstract

Objective: To evaluate the outcome of bilateral myringoplasty in dry central perforation in one sitting. Study Design: Interventional, descriptive. Place and Duration of Study: Department of ENT, Head & Neck Surgery, Dow University of Health Sciences& Civil Hospital Karachi, from September 2010 to September 2012. Methodology: A total of 30 patients above the age of 15 years were included in the study, who had dried bilateral perforated eardrum involving pars tensa. In majority of the cases, temporalis fascia graft was harvested from the larger perforation side through post aural incision and permeatal approach was employed on the smaller perforation side. Patients were followed up after 3 and 6 months to assess closure of tympanic membrane perforation and hearing improvement as depicted by closure of air above gap on pure tone audiometry at 6months. Results: A total of 60 myringoplasties were performed on 30 patients included in the study. Majority of the patients included were having medium to large size perforation in 29 (48.3%) and 18 (30%) ears respectively. Subtotal perforation was noted in 9 (15%) ears and only 4 (6.6%) ears were having small perforation. Successful closure of anatomic defect of tympanic membrane was achieved in 56/60 (93.3%) ears. with an average hearing gain of 16 dB. Conclusion: Bilateral myringoplasty is safe and effective procedure in patients with bilateral dry central perforation of tympanic membrane. It may be performed in one sitting with equally good anatomical and functional results as achieved in unilateral myringoplasties
