Role of Hyaluronic Acid Gel as an Adjunct to Temporalis Facia Graft in Tympanoplasty for Total Tympanic Membrane Perforation

Aim: the aim of the study is to compare the results of tympanoplasty using hyaluronic acid gel as an adjunct to temporalis fascia graft with tympanoplasty using temporalis fascia graft. Study Design: A prospective single blinded randomized controlled trial that will be carried out on 60 cases with total tympanic membrane perforation who will undergo tympanoplasty at our tertiary referral center. All involved cases will have grade IV tympanic membrane perforation based on Saliba classification for tympanic membrane perforation. The patients will be randomly divided into 2 groups A and B. Patients in group A will undergo underlay tympanoplasty using temporalis fascia graft with the utilization of hyaluronic acid gel was used as an adjunct to temporalis fascia graft. Patients in group B will undergo classic underlay tympanoplasty using temporalis fascia graft. The two group will be compared as regards: 1. Graft success rate. 2. Hearing outcome 3. Surgical complications
