To assess the feasibility of a postauricular transcortical mastoidectomy utilizing an exoscope, which offers 3D stereoscopic visualization.
Clinical capsule report.
Two consecutive patients with cholesteatoma involvement in the mastoid cavity were included in the study.
After transcanal endoscopic surgery, postauricular mastoidectomy utilizing a surgical 3D exoscope was performed. Then, the cholesteatoma in the mastoid cavity was removed through the mastoidectomy opening with endoscopes.
The postauricular transcortical mastoidectomy utilizing a 3D exoscope was not only feasible, but importantly, the exoscope took little time to switch to and resulted in a smooth workflow. There was no cholesteatoma recurrence at 9 months.
During endoscope-based surgery, in patients with cholesteatoma mastoid involvement, we can continue to perform the surgical procedure in a heads-up position utilizing a surgical 3D exoscope. The combination of transcanal endoscopic ear surgery and the postauricular transcortical mastoidectomy utilizing a surgical 3D exoscope is a very novel treatment strategy for cholesteatoma, and it gives us a comfortable and consistent working environment in endoscope-based ear surgery.
评估使用提供 3D 立体视觉的手术外窥镜进行耳后经皮质乳突切除术的可行性。
临床案例报告。
本研究纳入了 2 例乳突腔有胆脂瘤累及的连续患者。
在经耳道内镜手术后，使用手术 3D 外窥镜进行耳后经皮质乳突切除术。然后，通过内窥镜经乳突切开术清除乳突腔内的胆脂瘤。
使用 3D 外窥镜进行耳后经皮质乳突切除术不仅可行，而且外窥镜的切换时间很短，手术流程非常顺畅。9 个月后无胆脂瘤复发。
在基于内窥镜的手术中，对于乳突腔有胆脂瘤累及的患者，我们可以继续在头高位使用手术 3D 外窥镜进行手术。经耳道内镜耳外科与手术 3D 外窥镜辅助耳后经皮质乳突切除术的结合是胆脂瘤的一种非常新颖的治疗策略，它为我们提供了一个基于内窥镜的耳外科手术中舒适且一致的工作环境。
