Success Rate of Simple Underlay Myringoplasty in Smaller Perforation of Tympanic Membrane

Abstract

Introduction: The objective of the study was to compare the success rate of Simple Underlay Myringoplasty (SUM) in smaller perforation of tympanic membrane (TM) with that of Conventional Underlay Myringoplasty.

Methods: It was a prospective, longitudinal study on 46 patients of more than 15 years of age with Chronic Otitis Media Mucosal type with the small and medium sized perforations. The patients with average hearing loss more than 30 dB were excluded from the study. The patients were randomized into two groups: group A- who underwent SUM (26 patients) and group B-who underwent Conventional Myringoplasty (20 patients). The patients were followed up on 6th, 8th and 10th post operative week for the assessment of the status of the graft. The status was described as; intact TM, graft with residual pin point perforation and total rejection of the graft with remaining perforation.

Results: There was no statistical difference in graft status between SUM and Conventional Myringoplasty in all the three post operative follow up (p value = 0.121, 0.279 and 1.0 in 6th, 8th and 10th week of follow up respectively).

Conclusion: Simple Underlay Myringoplasty has comparable success rate (88.46%, 23/26) as Conventional Underlay Myringoplasty (90.0%, 18/20).
