Background: The endoscope has diagnostic and therapeutic role in different otological surgeries. It has excellent view of images where there are difficult nooks and corners. The use of sandwich cartilage perichondrium in the repair of tympanic membrane peroration has its own benefit in graft uptake and hearing results whether long term or short term. The main purpose of the present study was to evaluate the long-term hearing results in patients who underwent endoscopic sandwich myringoplasty with Dhulikhel Hospital (D-HOS) technique. Materials and Methodology: This was a prospective, cohort study performed among 45 patients who underwent endoscopic sandwich myringoplasty with D-HOS technique using tragal cartilage and perichondrium. The hearing was assessed by comparing pre- with post-operative air-bone gap (ABG) and ABG closure in speech frequencies (0.5 kHz, 1 kHz, 2 kHz, and 4 kHz). Results: Among forty-five patients, 42 (93.3%) had graft uptake in 12 months of follow-up. The postoperative ABG (17.0 ± 8.5 dB) was lesser than preoperative ABG (27.3 ± 12.5 dB) with statistically significant results. Conclusion: Endoscopic sandwich myringoplasty with D-HOS technique is a safe procedure with high-graft uptake rate and good long-term hearing results.
