OBJECTIVE
Evaluation of an endoscopic anatomic classification of the external auditory canal (EAC) for transcanal endoscopic ear surgery.
MATERIALS AND METHOD
The EAC Canal Endoscopic Scale (CES) was initially defined according to total or partial EAC narrowing on 0° transcanal endoscopy. A retrospective study was then conducted between September 2013 and March 2015 in a series of consecutive patients fulfilling the study inclusion criteria.
RESULTS
A total of 83% of 5000 patients (10000 ears) were classified as CES 0: i.e., total visualization of the tympanic membrane. Various kinds of EAC narrowing were described. Results were comparable between right and left ears.
CONCLUSIONS
0° endoscopy provided total visualization of the tympanic membrane in most cases, thanks to its magnified lateral view. Preoperative CES classification allows use of angled endoscopes, curved instruments or drilling for canalplasty to be planned in the first step of transcanal endoscopic ear surgery.
目的
评估经耳道内镜耳部手术中行外耳道内镜解剖分类。
材料与方法
根据经耳道内镜下外耳道完全或部分狭窄，最初定义外耳道内镜测量尺（CES）。2013 年 9 月至 2015 年 3 月对一系列符合研究纳入标准的连续患者进行回顾性研究。
结果
5000 例患者（10000 耳）中的 83%被分为 CES0：即鼓膜的完全可见。描述了各种类型的外耳道狭窄。左右耳结果相当。
结论
由于其放大的侧视图，0°内镜检查在大多数情况下可提供鼓膜的完全可见性。术前 CES 分类允许在经耳道内镜耳部手术的第一步中计划使用角度内镜、弯曲器械或钻孔进行耳道成形术。
