Introduction: This study was aimed to assess the hearing outcome after type I tympanoplasty using temporalis fascia graft, to assess the factors which influence the outcome and to evaluate the result of our study and to compare our data with similarly published study. Materials and methods: The study was conducted at NSCB Medical College and Hospital, Jabalpur in the Department of Otorhinolaryngology after obtaining approval from the institutional ethics committee, from October 2014 till October 2015. Patients, aged 15 to 45 years, presenting with perforated tympanic membrane were consented. Audiological evaluation was done preoperatively, 1 month and 3 month after tympanoplasty. Results: During the study period 45 type I Tympanoplasty were performed using temporalis fascia as graft, 24 males. 21 cases below the age of 26 years showed graft take up of 84% and the mean hearing gain of 11.37 dB. 77% of those belonging to low socioeconomic group showed graft take up of 76.9% with mean hearing gain of 12.03 dB and 88% of those belonging to high socio economic group showed graft take up of 87.5% with mean hearing gain of 11.14 dB. Out of 21 cases which had perforation size <50% 20 showed graft take up of 95.23% with mean hearing gain of 11.77 dB. Conclusions: Graft uptake is independent of gender, age of the patient. Pre operative dry ear status is directly related to the outcome of surgery. Graft take up is better in perforation size less that 50% but hearing gain will be more in perforation size of more than 50%.
