Comparison of Endoscopic Modified and Typical Myringoplasty: A Randomized Controlled Trial.

Abstract

Here, we aimed to compare the operation time, postoperative pain score, graft healing, graft success rate, cholesteatoma incidence, audiometric outcomes, and complications between endoscopic modified myringoplasty (EMM) and endoscopic typical myringoplasty (ETM). Patients with unilateral chronic tympanic membrane (TM) perforations undergoing myringoplasty were prospectively randomized to undergo EMM (n=44) or ETM (n=45). The operation time, postoperative pain score, graft healing, graft success rate, cholesteatoma incidence, audiometric outcomes, and complications were compared between these groups. In total, 89 patients with unilateral chronic perforations were included (EMM group, 44; ETM group, 45). There were significant differences between the EMM and ETM groups in mean pain scores on the day after surgery (1.32 ± 0.56 vs. 2.58 ± 1.16, p < 0.001) and in the mean operation time (18.18 ± 2.43 vs. 51.53 ± 8.28 min, p < 0.001). There were no significant differences in graft success rates (93.18% vs. 88.89%, p=0.735), pre- or postoperative air conduction pure-tone averages or air bone gaps (ABGs), or changes in ABGs between the groups. However, the difference in graft healing was significant at postoperative week 2 (33/44 vs. 24/45, p=0.033) but was nonsignificant at postoperative week 4 and month 6. Computed tomography revealed the middle ear and mastoid to be well pneumatized at 12 months in all patients. While 12-month graft and audiometric outcomes were comparable between EMM and ETM techniques, patients who underwent EMM had less postoperative pain, shorter operative times, faster healing, and a lower incidence of complications. 1 Laryngoscope, 133:2779-2785, 2023.
