Abstract

Type I tympanoplasty (myringoplasty) is commonly performed procedure for chronic otitis media, mucosal type involving the repair of tympanic membrane perforation. We conducted the present study on 64 patients (71 ears) and evaluated post-operative hearing status (functional outcome) and post-operative intake of graft (anatomical outcome) 3 months after surgery. On pre-operative audiometry, 70% of patients were having hearing threshold between 26-40dB, 14% had 0-25dB, 16% had more than 40dB. The graft uptake was present in 87.3% patients. Graft uptakes were maximum in small perforations (92.5%) followed by posterior perforations (90.9%) and least in large and subtotal perforations (66.6%). On post-operative audiometry, 73.5% of patients had hearing threshold <25dB, 17.4% had 26-40dB and 8.9% had threshold >40dB. The present study concludes that type I tympanoplasty when performed in a dry ear with best surgical technique yields batter success rate both in terms of anatomical and functional outcome.
