To investigate clinical significance of non-recurrent laryngeal nerve.
Clinical data from 4 cases of non-recurrent laryngeal nerve and related literature review was made to acknowledge its incidence, variant types and matters concerned during thyroid surgery.
Seven hundred and nineteen recurrent laryngeal nerves were exposed during 2156 thyroid operations in Xiangya Hospital, from which 4 were confirmed to hold non-recurrent laryngeal nerves (0.56%). Two cases were found on the right side and the other 2 on the left. Among the 4 cases, 3 (patients) were found to have non-recurrent laryngeal nerves during reoperation because of voice horse after the first operation. The other one was recognized during the first operation.
Non-recurrent laryngeal nerve, a rare anomaly, is very vulnerable during thyroid surgery. Knowing the related knowledge of the non-recurrent laryngeal nerve and its types is helpful to avoid its damage during thyroid surgery.
探讨非返喉返神经的临床意义。
回顾性分析4例非返喉返神经患者的临床资料，并复习相关文献，了解其发生率、变异类型及甲状腺手术中应注意的事项。
中南大学湘雅医院2156例甲状腺手术中，共显露喉返神经719条，其中发现非返喉返神经4条（0.56%），右侧2条，左侧2条。4例中，3例因首次手术后声音嘶哑再次手术时发现非返喉返神经，另1例在首次手术时发现。
非返喉返神经是一种罕见的变异，在甲状腺手术中极易受损。了解非返喉返神经的相关知识及其类型，有助于在甲状腺手术中避免损伤该神经。
