Efficacy of Underlay Versus Overlay Technique for Myringoplasty in Terms of Hearing Improvement.
J Med Sci Jan ;30(2):114-6.

Objectives: To compare the efficacy of the underlay and overlay techniques for myringoplasty among patients with perforated tympanic membrane in terms of improvement in the hearing.Material and Methods:This study was performed in the department of ENT Hayatabad Medical Complex, Peshawar from Jan-uary 2019 to December 2019. A total of 164 patients were randomly allocated into two groups. In group A patients (n=82), the underlay technique was performed while in group B patients (n=82) overlay technique was performed. Temporalis fascia was used for grafting in all cases. All procedures were performed under general anesthesia. All patients were followed at 3 months to determine the effectiveness in terms of improvement in the air-bone gap of at least 10db.Results:As per efficacy in both groups, in Group A, 70 (85.36%) patients showed effectiveness while in Group B, only 52 (63.41%) patients showed effectiveness (P-Value < 0.001).Conclusion:Theunderlay technique improved the air-bone gap by at least 10dB in a significantly (P < 0.001) higher number of patients as compared to the overlay technique.
