Abstract

Aim: to evaluate the outcome of tympanoplasty type I using dry and wet temporalis fascia graft. Methods The present Randomized control trial was conducted in the Department of ENT, Sri Krishna Medical College and Hospital, Muzaffarpur, Bihar . Among 100 patients attended the OPD of the ENT and diagnosed with chronic suppurative otitis media. Patients were divided into 2 groups of 50 each: one group underwent dry graft tympanoplasty and the other underwent wet graft tympanoplasty. Results: The dry graft and wet graft groups had overall surgical success rates of 82 and 88 per cent, respectively; this finding was not statistically significant. A statistically significant high fibroblast count was observed in wet grafts. Conclusion: The present study concluded that the dry or wet temporalis fascia graft did not affect the outcome of type I underlay tympanoplasty significantly. However, using wet temporalis fascia could shorten the duration of surgery in type I underlay tympanoplasty. Keywords: tympanoplasty; wet graft, dry graft, temporalis fascia

Summary

Introduction

Chronic otitis media is a widespread disease of developing countries such as India, especially in rural areas, and the prevalence ranges from 2% to 15%.1Tympanoplasty is a commonly performed surgical procedure to close perforations of the tympanic membrane in chronic otitis media. It is performed to eradicate disease from the middle ear cleft and to reconstruct the hearing mechanism with or without tympanic membrane grafting.[2]. In 1960, Hermann introduced the use of a temporalis fascia graft in tympanoplasty.[3] Shea introduced the underlay technique of tympanoplasty at the same time that Hermann introduced the temporalis fascia graft.[4] A year later, in 1961, Austin and Shea modified this technique by incorporating a tympanomeatal flap elevation.[5] In 1973, Glasscock described the use of a post-auricular approach for underlay tympanoplasty; this is a standard procedure worldwide.[6] An impressive success rate of more than 90 per cent is routinely observed with this technique.[7]
