This study aimed to evaluate the procedural outcomes and learning curve of type I endoscopic tympanoplasty (ET) performed by a single surgeon.This was a retrospective study of 376 patients who underwent type I ET performed by a single surgeon over 7 years. We evaluated the pre/post air-bone gap (ABG), time required for surgery, changes in pain after surgery, success, and failure rate of type I ET.Hearing results indicated an ABG of approximately 17.8 dB before surgery but decreased significantly to 9.8 dB at 6 months after surgery. The time required for the operation gradually decreased. In particular, the time required for the procedure was 67.6 min in the first year and decreased to 31.5 minutes in the fifth year, a drastic reduction. The graft failure rate up to 6 months after surgery was 13.0% and was the same for both primary and revision surgeries. Graft failure was significantly greater with increasing size of the preoperative tympanic perforation. The success rate varied depending on graft material, and the group with only acellular allogenic dermal matrix showed the lowest success rate. Postoperative pain significantly decreased from 2.01 immediately after surgery to 0.78 points the next day, and there were no severe complications during surgery.ET produces superior cosmetic results with minimal pain and is associated with stable hearing improvement and high success rate. The operation time decreased with surgeon experience and continued to decrease until the fifth and final year of this analysis.4. |
