OBJECTIVE
This study aimed to compare the hearing results of two different stapedotomy techniques used in the clinic at different time points.
METHODS
An endoscopic surgery group (group 1; n = 37) were compared retrospectively with a microscopic surgery group (group 2; n = 57). A small fenestra and Teflon piston technique were used in all patients. Bone cement was used for fixation between the prosthesis and incus in the endoscopic group only. Bone conduction threshold and air-bone gap were used as the comparison parameters.
RESULTS
The pre-operative air-bone gap was 31.26 dB in group 1 and 32.51 dB in group 2. The post-operative air-bone gap was 8.93 dB in group 1 and 14.28 dB in group 2. There was a significant difference between the groups in post-operative air-bone gaps. There was no significant difference between the groups in post-operative bone conduction thresholds.
CONCLUSION
The endoscopic technique using bone cement fixation was better for closing the air-bone gap.
目的
本研究旨在比较临床中在不同时间点使用的两种不同镫骨手术技术的听力结果。
方法
将内镜手术组（第1组；n = 37）与显微镜手术组（第2组；n = 57）进行回顾性比较。所有患者均采用小开窗和聚四氟乙烯活塞技术。仅在内镜组中使用骨水泥固定假体与砧骨。将骨导阈值和气骨导间距用作比较参数。
结果
第1组术前气骨导间距为31.26 dB，第2组为32.51 dB。第1组术后气骨导间距为8.93 dB，第2组为14.28 dB。两组术后气骨导间距存在显著差异。两组术后骨导阈值无显著差异。
结论
使用骨水泥固定的内镜技术在闭合气骨导间距方面效果更好。
