OBJECTIVE
This study aimed to assess whether increasing operative experience results in better surgical outcomes in endoscopic middle-ear surgery.
METHODS
A retrospective single-institution cohort study was performed. Patients underwent endoscopic tympanoplasty between May 2013 and April 2019 performed by the senior surgeon or a trainee surgeon under direct supervision from the senior surgeon. Following data collection, statistical analysis compared success rates between early (learning curve) surgical procedures and later (experienced) tympanoplasties.
RESULTS
In total, 157 patients (86 male, 71 female), with a mean age of 41.6 years, were included. The patients were followed up for an average of 43.2 weeks. The overall primary closure rate was 90.0 per cent.
CONCLUSION
This study demonstrates an early learning curve for endoscopic ear surgery that improves with surgical experience. Adoption of the endoscopic technique did not impair the success rates of tympanoplasty.
目的
本研究旨在评估增加手术经验是否会使内镜中耳手术获得更好的手术效果。
方法
进行了一项单机构回顾性队列研究。患者于2013年5月至2019年4月间接受了由资深外科医生或在其直接监督下的实习外科医生进行的内镜鼓室成形术。收集数据后，统计分析比较了早期（学习曲线阶段）手术和后期（经验丰富阶段）鼓室成形术的成功率。
结果
共纳入157例患者（男性86例，女性71例），平均年龄41.6岁。患者平均随访43.2周。总体一期愈合率为90.0%。
结论
本研究证明内镜耳手术存在早期学习曲线，且随着手术经验的增加而改善。采用内镜技术并未损害鼓室成形术的成功率。
