Background: Patients with a mucosal type of chronic otitis media (COM) usually have recurrent ear discharge and conductive hearing loss. It is characterized by the central perforation of the tympanic membrane. Myringoplasty is an operation performed to repair tympanic membrane perforation when there is no ossicular damage. Aim: The purpose of this study was to evaluate hearing outcome in tympanic perforation patients undergoing Tympanoplasty. Methods: A total of 80 patients who underwent underlay myringoplasty at Jaipur Golden Hospital, New Delhi over a period of 20 months were enrolled in this study. The Myringoplasty surgery was done in all patients fulfilling preoperative inclusion criteria. The Audiometric evaluation was conducted at follow up after 3 months postoperatively and results were compared with preoperative hearing level and tympanic membrane status. Results: Out of total 76 cases was followed up and 04 Cases were lost in follow up. Graft take up rate achieved was 97.37%. Post operative hearing improvement was found in 72 (94.74%) patients. The mean pre-operative air bone gap was 30.39dB±4.56 SD while after surgery it was 16.39dB ±6.55 SD (p<0.001). Majority of patients i.e. 54 (71.05%) had hearing gain in the range of 11-20 dB. On an average 10.25dB hearing gain was seen in patients with small central perforation, 13.15dB ±6.89 SD in patients with medium size central perforation and 15.6dB ±4.83SD hearing improvement was noted in patients with large size central perforation. Conclusion: Underlay myringoplasty is an effective surgical technique for the repair of tympanic membrane perforations in terms of graft take up and improvement of hearing.
