Different Grafts used In Closure of Central Small Tympanic Membrane Perforations

Abstract

Background: Large number of patient seek ENT consultation for central perforation of tympanic membrane. A significant portion of these cases are often found with very small central perforation. Minimyringoplasty is a very simple procedure to close such small perforations. Objective: the aim of the present study is to compare the surgical and audiological results of temporalis fascia versus more simple methods ( fat graft, fat graft wih hyaluronic acid and platelet rich plasma)in myringoplasty. Patient and Methods: a randomized prospective study concerned with 80 patients for whom myringoplasty was done. Patients were randomly assigned into four groups; in the first group fat graft was used (20patient) and fat graft with hyaluronic acid was used in the second group (20 patients).and platelet rich plasma was used in third group (20 patients) and temporalis fascia was used in fourth group (20 patients). Results: our study included 80 patients, 45 males and 35 females with a range from 18- 55 years. Surgical success rates75% , 80%, 75%and 75%for fat graft, fat graft with hyaluronic acid, platelet rich plasma and temporalis fascia respectively. There was 6.5 dB, 7db , 6 db and 5.5 db mean hearing improvement improvement in fat graft, fat graft with hyaluronic acid, platelet rich plasma and temporalis fascia respectively. Conclusions: The myringoplasty with fat graft,fat graft with hyaluronic acid and PRP is a minimally invasive effective procedure in management of the small central tympanic membrane perforations . Also it is safe and feasible procedure In this study we have achieved High success rate of repair of tympanic membrane perforation.
