Background: Endaural, post-auricular, and permeatal/transcanal access to the tympanic membrane are the three acknowledged surgical techniques for myringoplasty. In general, the preferred method is determined by the location of the hole and the surgeon's experience. Objective: In this study our main goal is to evaluate the factors affecting surgical outcome of myringoplasty in rural patients Bangladesh. Method: This cross sectional study was done at tertiary medical hospital from Feb 2021 to Feb 2022. Where 100 patients were divided into several groups based on factors like size of perforation (small, medium and large), site of perforation (anterior central, posterior central and central malleolar), surgical approach (post auricular and transcanal). Results: During the study, where 60% cases were Central malleolar and 35% were Posterior central. 45% cases had medium size of perforation. According to improvement of hearing thresholds after myringoplasty in relation to the size of the perforation where The closure of air-bone gap in small, medium and large perforation was 11.15 dB, 20.61 dB and 18.55 dB respectively. The difference of air bone gap closure between small and larger perforation was statistically significant by unpaired t-test (p<0.001). In addition, according to improvement of hearing thresholds after myringoplasty in relation to the site of perforation and surgical approach where closer of air bone gap was maximum (20.90 dB) in central malleolar perforation and minimum (12.11 dB) in posterior central perforation. Which was statistically significant from unpaired t-test (p<0.001). In addition, closure of air bone gap was more in dry ear. The difference between two groups was statistically significant from unpaired t-test (p< 0.02). Conclusion: We concluded from this study that the location and extent of tympanic membrane perforation, as well as the state of the middle ear, influence surgical result following myringoplasty.
