    Abstract

    Introduction: Comparative study of myringoplasty (CSOM) with perforation is one of the common otological condition for which patients seek advice from otorhinolaryngologist. Materials and methods: The study was carried out on patients diagnosed as CSOM in ENT department. Fifty patients were operated for myringoplasty with underlay (25) or overlay (25) technique with temporalis fascia as a graft material. The audiological evaluation was done after 3 months. Results and observation: Total 82% cases showed improvement in hearing. The mean preoperative hearing loss was 35.90 (+8.433 SD), and postoperative was 25.40 (+5.962SD) on paired t-test the differentiating factor was 8.832 and p ≤ 0.001 which is statistically highly significant. Mean improvement in hearing using temporalis fascia and underlay technique was 9.8 dB (+ 7.702 SD) and overlay technique was 11.2db (+ 9.160 SD. Conclusion: On applying paired t-test, the differentiating factor was 0.585 and p = 0.561 which is statistically nonsignificant. Thus underlay and overlay technique of myringoplasty are equally effective.
