Abstract：
OBJECTIVE: To discuss the treatment of external auditory canal stenosis or atresia occurring as a complication of transcanal endoscopic ear surgery.
METHODS: We retrospectively analyzed the medical records of 11 patients who developed external auditory canal stenosis or atresia after undergoing transcanal endoscopic ear surgery. The 10 patients with stenosis were treated with external auditory canal expansion via drainage tube insertion; 2 of these patients further received local injections of triamcinolone acetonide. One patient with atresia was treated with meatoplasty surgery followed by tube insertion and triamcinolone acetonide injection.
RESULTS: The stenosis/atresia improved in all patients, and the external auditory canal was unobstructed without restenosis.
CONCLUSIONS: Stenosis/atresia of the external auditory canal after transcanal endoscopic ear surgery should be treated with dilation therapy/meatoplasty in a timely manner to prevent progressive hyperplasia of the scar and regain a normal-sized ear canal.

摘要：
目的：探讨经耳道内窥镜手术并发症外耳道狭窄或闭锁的治疗方法。
方法：我们回顾性分析了11例经耳道内窥镜手术后出现外耳道狭窄或闭锁的患者的病历。10例狭窄患者通过引流管插入外耳道扩张治疗；这些患者中有2例进一步接受了曲安奈德的局部注射。一名闭锁患者接受了手术成形术，然后插入管和曲安奈德注射。
结果：所有患者的狭窄/闭锁均得到改善，外耳道通畅，无再狭窄。
结论：经耳道内窥镜手术后的外耳道狭窄/闭锁应及时进行扩张治疗/移植治疗，以防止瘢痕的进行性增生，恢复正常大小的耳道。
