Objectives: To introduce and evaluate a modified endaural approach for type 1 tympanoplasty by comparing its ana- tomical and functional outcomes with those of the classical postauricular and endoscopic transcanal approaches. Methods: We retrospectively analyzed 86 patients (≥16 years) with subtotal tympanic membrane perforations who underwent type 1 tympanoplasty between 2015 and 2021. Patients were grouped based on surgical approach: en- doscopic transcanal (Group A, n=28), postauricular (Group B, n=31), and modified endaural (Group C, n=27). Pre- and postoperative air-bone gap (ABG), graft success rates, complications, and operation durations were compared. Results: The mean operation duration was significantly shorter in Groups A (40.3±0.9 min) and C (45.1±1.4 min) than in Group B (61.3±1.6 min) (p<0.0001). Graft success rates were similar across groups: 85.8% in Group A, 83.9% in Group B, and 85.2% in Group C. Pre- and postoperative ABG improvements did not differ significantly among groups. No major complications were observed in Group C, while minor complications occurred in Groups A and B. Conclusion: The modified endaural approach offers comparable anatomical and functional outcomes to classical tech- niques while reducing operation time and bleeding. This technique is especially advantageous for patients with narrow external auditory canals or posterior perforations and allows the comfortable use of both microscope and endoscope.
