ABSTRACT

Background: Tympanoplasty is the well-established procedure for closure of perforations of tympanic membrane. Objective: In this study our main goal is to evaluate the results of dry and wet temporalis fascia graft on tympanoplasty. Method: A prospective, randomized, comparative study was carried out at the ENT and pathology departments of Tertiary medical college and hospital from 2017 to 2019. The study sample comprised 80 adult patients of either sex. These patients were selected from the ENT out-patient department, and randomly divided into 2 groups of 40 each for dray and wet graft. Results: During the study, in both group most of the patients belong to 32-42 years age group, 58% in dry graft and in wet graft it was 62.5%. According ear status, 70% cases reported ear discharged followed by 57% cases decreased hearing, 38% had ear pain, 20% had tinnitus and 22% cases had ear block. When it comes to fibroblast count findings demonstrate that fibroblast count was significantly higher in the wet graft group. Whereas, while evaluating perforations site in the dry graft group, out of 40 patients, none had anterior, 34 had inferior and 6 had posterior perforations. Success rates of 88.2 per cent and 83.3 per cent were recorded for inferior and posterior perforations, respectively. Where as in wet group Success rates of 66.7 percent, 97.14 per cent and 50 per cent were recorded for anterior, inferior and posterior perforations, respectively. And after evaluation performance in dry graft group successes’ rate was 85% where as in wet graft it was 89%. Conclusion: From our findings it was found that, age, gender, and moist ear had no effect on tympanoplasty graft uptake. There was no difference in graft absorption between the dry and wet ears, and there was no statistically significant difference in hearing improvement between the dry and wet ears. These conclusions are based on our limited experience and are offered to stimulate debate and future study on the issue.
