Abstract

Background: The three-dimensional (3D) exoscope is an emerging alternative to the operating microscope (OM) in otologic surgery.

Aims: To assess its clinical utility in cholesteatoma surgery.

Methods: Retrospective review of 36 primary cases (21 OM, 15 exoscope) comparing setup time, surgical duration, audiological outcomes, and recurrence.

Results: Groups were comparable in background and stage. Setup time was shorter with exoscope (microscope: 20 min, range 18-22, exoscope: 17 min, range 14-20) (p = .002), while other outcomes showed no significant difference.

Conclusions: The 3D exoscope reduced setup time with equivalent surgical and functional outcomes to OM.

内镜下与三维外窥镜下鼓室乳突切除术治疗原发性中耳胆脂瘤的比较。

背景：三维（3D）外窥镜是一种新兴的替代手术显微镜（OM）在耳科手术。目的：评价其在胆脂瘤手术中的临床应用价值。方法：回顾性分析36例原发病例（21例OM， 15例外窥镜），比较手术时间、手术时间、听力学结果和复发情况。结果：各组在背景和分期上具有可比性。外窥镜的设置时间较短（显微镜：20 min，范围18-22；外窥镜：17 min，范围14-20）（p = 0.002），而其他结果差异无统计学意义。结论：3D外窥镜减少了安装时间，与OM具有相同的手术和功能效果。
