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

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. Prior to study conduction, institutional ethics committee approval was obtained (code: MS.19.04.576). Informed written consents well be obtained from all cases before surgeries. All involved cases will have grade IV tympanic membrane perforation based on Saliba classification for tympanic membrane perforation where the perforation was total perforation involving the entire four quadrants of the tympanic membrane. All the cases will have inactive dry ear for at least 2 months prior to surgeries. All involved cases will be ≥18 years old. Excluded cases include revision cases, cases with active (discharging ear), cases \< 18 years old, immunocompromised cases and cases who missed to follow up. The patients will be randomly divided into 2 groups A and B using computer generated block randomization. Patients in group A will undergo underlay tympanoplasty using temporalis fascia graft through postauricular approach 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 through postauricular approach. The two group will be compared as regards: 1. Graft success rate. 2. Hearing outcome 3. Surgical complications
