Background: The current study aims to compare type 1 microscopic tympanoplasty and endoscopic tympanoplasty and draws an evidence-based conclusion regarding the outcome.

Methods: This randomized controlled clinical study consists of 60 patients, in which 30 cases allocated as group 1 underwent endoscopic myringoplasty, and 30 cases allocated as group 2 underwent conventional myringoplasty. Tympanic membrane (TM), pure tone audiometry (PTA) evaluated preoperatively and at 3 months postoperative follow-up.

Results: Demographic distribution between the groups does not show a significant difference (χ2=6.67, p=0.16). There was no significant difference observed between TM perforation size between the groups (χ2=2.32, p=0.51). For the preoperative AB gap in group 1, the mean ABG was 28.20±2.67 and in group 2 was 28.20±0.80. The postoperative AB gap in group 1, the mean ABG was 17.40±3.01, and in group 2, the mean ABG was 19.67±2.93. The mean difference is 9.13, and it shows a statistically significant difference (p=0.001). The mean duration of surgery in group 1 was 130.83±34.84 and in group 2 was 168.33±16.88 min (p=0.001). In both groups, 90% have intact graft, and in 10% of patients’ residual perforation is present. The mean duration of hospitalization in group1 is 4.10±0.09 days and in group 2 is 4.97±0.18 days.

Conclusions: By using the endoscopic addition, minimal invasive tympanoplasty can made possible the similar graft success rate with minimal pain. Endoscopic tympanoplasty uses very less operative time than microscopic surgery.
