ABSTRACT

Background: Tympanoplasty is the operative procedure performed to repair the tympanic membrane perforation and to improve hearing level. The materials used range from fascia, perichondrium, duramater, skin, homograft and autograft to synthetic prosthetic material. In this study, we have compared the use of temporalis fascia and fascia lata as graft material in tympanoplasty and compare with postoperative graft taken up and hearing assessment i.e. Pre and post operatively hearing assessment. Methodology: Patients with Chronic otitis media having large, subtotal or total central perforation with >25dB conductive hearing loss were operated with Tympanoplasty. Grafts used were either temporalis fascia or fascia lata. Patients were randomly selected for each group. Results: Graft take up rate for both fascia lata and temporalis fascia was 95 %. Graft Uptake was not dependent on type of graft but it depended on size of perforation. Smaller and moderate perforations had better uptake than large perforations. Hearing gain in temporalis fascia was 30.5 dB and in fascia lata was 30 dB. Conclusion: Overall graft uptake rate and Hearing improvement were almost equal with both temporalis fascia and fascia lata. Graft Up take was not dependent on type of graft but it depended on size of perforation. Small and moderate perforations had better uptake than large perforations. Temporalis Fascia is used frequently as compared to fascia lata as it is easily available in sufficient quantity and for harvesting separate incision is not required.
