Surgery for congenital auricular atresia places the facial nerve at risk because of its potential aberrancy; iatrogenic facial paralysis is a well-known potential risk. Five cases of congenital auricular atresia are presented. All patients had intraoperative monitoring of the facial nerve. The facial nerve was found to be abnormally displaced, usually due to hypoplasia of the tympanic ring. Preoperative and postoperative facial nerve function was unchanged by surgery. Facial nerve monitoring is an important adjunct in congenital ear surgery because it allows for early and precise identification of the nerve in the absence of normal surgical landmarks and provides for continuous monitoring of the nerve.
先天性耳闭锁手术因面神经可能存在走行异常而使其面临风险；医源性面瘫是一种众所周知的潜在风险。本文报告了5例先天性耳闭锁病例。所有患者术中均进行了面神经监测。发现面神经移位异常，通常是由于鼓环发育不全所致。手术前后面神经功能未发生改变。面神经监测是先天性耳部手术的一项重要辅助手段，因为它能在缺乏正常手术标志的情况下早期精确识别面神经，并对其进行持续监测。
