The non-recurrent course of the inferior laryngeal nerve is a rare anomaly. The incidence varies from 0.3 to 4% on the right side. It is extremely rare on the left side. The awareness of such an anomaly is essential as the risk of damage to the nerve is higher during thyroid surgery. Two cases of non-recurrent laryngeal nerve are reported, and the embryology and method of identification are discussed.
喉下神经非折返行径是一种罕见的异常情况。右侧发生率为0.3%至4%。左侧极为罕见。由于甲状腺手术期间神经损伤风险较高，认识到这种异常情况至关重要。本文报告了两例喉下神经非折返病例，并讨论了其胚胎学及识别方法。
