Myringoplasty: A Retrospective Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 8
Abstract
Background: Myringoplasty is the most commonly done surgery in the field of otology. It is a beneficial procedure done for closing tympanic membrane perforations and improving hearing. Objective: The aim of this study was to assess hearing results after myringoplasty at 1 month and at 3 months postoperatively and to compare the graft uptake rates in perforations of different sizes and at different sites. Materials and Methods: The study population consisted of 100 patients who were suffering from chronic suppurative otitis media-tubotympanic pre-operative air-bone (AB) gap which were calculated by taking averages of bone conduction and air conduction at the frequencies of 500, 1000, and 2000 Hz. Myringoplasty was performed with underlay technique under local anesthesia by postaural routes using temporalis fascia as grafting materials. Patients were called for follow-up at 1 and 3 months postoperatively and hearing evaluation was done and compared with pre-operative. The status of the graft was determined at each follow-up otoscopically. Results: In a total of 30 cases of small perforations, graft was intact in 25 patients with a success rate of 83.33%. In a total of 50 cases of medium-sized perforations, graft was intact in 45 patients with success rate of 90%, whereas in 20 patients of subtotal perforations, the graft uptake was seen only in 12 patients with success rate of 60%. Graft uptake in 30 patients of anterior perforations was seen in 28 patients with a success rate of 93.3%. In 56 patients of posterior perforations, 48 patients showed graft uptake with a success rate of 85.71%, whereas in 14 patients of all quadrant perforation, only 6 showed graft uptake with a success rate of 42.85%. There was overall improvement in hearing in 87 (87%) patients and no improvement in 13% patients. Conclusion: Using the proportion of patients with a post-operative hearing within 40 dB as the criterion, in this study, 100% of patients achieved their hearing level within 40 dB. Using hearing gain exceeding 15 dB as the criterion, 87% of patients (87) had their hearing gain exceeding 15 dB. Using post-operative AB gap within 20 dB as the criterion, 96% of patients (96) had their AB gap within 20 dB.
