Objective:To investigate the surgical outcomes and safety of the follower arm endoscope holder in assisting type Ⅰ tympanoplasty. Methods:The clinical data of 16 patients who underwent type Ⅰ tympanoplasty at the Department of Otorhinolaryngology, Peking Union Medical College Hospital, from November 2022 to September 2023 were retrospectively analyzed, among which 8 cases were operated by traditional otoscopy and 8 cases were operated by supported endoscopy.The surgical procedure was analyzed and the completion of supported endoscopic operation was observed, while the duration of the operation, the time consumed by the main steps, the frequency of wiping the lenses, the perioperative complications, and the improvement of the postoperative hearing were recorded and statistically analyzed. Results:Supporting endoscopic technology achieved real-time suction of bleeding, simultaneous traction and separation of tissues, precise removal of calcified spots on the inner side of the eardrum, trimming of the external auditory canal flap, stable separation of the handle of the malleus and the eardrum, and tensioned repositioning of the skin-cartilage flap. The average duration of surgery, time for external auditory canal flap preparation, and time for repositioning the skin-cartilage flap were reduced in the supporting endoscopic surgery group compared to the control group. The average lens wiping frequency was significantly lower in the supporting endoscopic surgery group compared to the control group. There was no statistically significant difference in postoperative hearing improvement between the two groups, and no infections or the need for secondary surgery due to eardrum re-perforation occurred postoperatively. Conclusion:Supported endoscopy technology realizes the need for endoscopic two-handed operation and convenient switching between one and two hands, accomplishes many operations that cannot be done by traditional endoscopic surgery, solves the problems of previous intraoperative one-handed operation and image instability, shortens the average operation time compared with traditional otoscopic surgery, and decreases the frequency of intraoperative wiping of the lens significantly compared with traditional otoscopic surgery, which is potentially worthwhile in terms of shortening the learning curve.
目的：探讨支撑内镜技术辅助Ⅰ型鼓室成形术的手术效果及其安全性。 方法：回顾性分析2022年11月—2023年9月在北京协和医院耳鼻咽喉科接受Ⅰ型鼓室成形术的16例患者的临床资料，其中传统耳内镜手术组8例，支撑内镜手术组8例，分析手术流程，观察支撑内镜下操作的完成情况，同时记录手术持续时间、主要步骤耗时、擦拭镜头频率、围术期并发症及术后听力改善情况，并进行统计学分析。 结果：支撑内镜技术实现了耳内镜手术中实时吸除渗血，一手牵拉组织时另一手进行分离，精细去除鼓膜内侧钙化斑，修剪外耳道皮瓣，稳定分离锤骨柄和鼓膜，有张力地复位皮肤软骨膜瓣等操作。支撑内镜组的平均手术持续时间、外耳道皮瓣制作时间和皮肤软骨膜瓣复位时间较对照组减少，平均擦拭镜头频率较对照组明显下降。2组患者术后听力改善情况差异无统计学意义，术后均未发生感染或是因鼓膜再穿孔需要进行二次手术。 结论：支撑内镜技术实现了内镜下双手操作及单双手便捷切换的需求，完成了许多传统内镜手术无法完成的操作，解决了既往术中单手操作及图像不稳定等问题，平均手术时间较传统耳内镜手术缩短，术中擦拭镜头频率较传统耳内镜手术明显下降，具有缩短学习曲线的潜在价值。.
