Journal Title: Medpulse International Journal of ENT - Year 2017, Vol 4, Issue 3
Abstract
Background: Myringoplasty is a routine surgical procedure done in medical college hospitals. In this study we evaluate the hearing improvement in patients who had undergone Myringoplasty in a period of one year. Methods: In this prospective study 50 patients who were diagnosed as Chronic Suppurative Otitis Media (CSOM) with central perforation underwent Myringoplasty. Myringoplasty was performed using underlay technique by transcanal approach with an endoscope. Temporalis fascia graft was used for all patients. The data of all patients regarding pre operative perforation size, pure tone audiogram results, post operative graft uptake and post operative pure tone audiogram results were analysed. Results: Out of 50 patients, 42 (84%) had successful graft uptake. These 42 patients were subjected to pure tone audiometry post operatively. The results of pure tone audiometry in these 42 patients were analysed pre operartively and post operatively. Out of these 42 patients, 11 (26.19%) patients had 0-25dB Air Bone Gap (A-B Gap), 18 (42, 85%) had 26-40 dB Air Bone Gap and 13 (30.95%) had 40-50 dB Air Bone Gap preoperatively. Post operatively out of these 42 patients, 27 (64.28%) patients had 0-25dB Air Bone Gap (A-B Gap), 13 (30.95%) had 26-40 dB Air Bone Gap and 2 (4.76%) had 40-50 dB Air Bone Gap. Conclusion: Myringoplasty is an effective surgery to improve the hearing in CSOM with tubotympanic disease. The hearing improved significantly after surgery in these patients.
