Non-recurrent laryngeal nerve, a rare anomaly, passes transversely into larynx with or without its recurrent branches directly arising from the vagus nerve. The paper investigates clinical significance of non-recurrent laryngeal nerve during thyroid surgery. Clinical data from 5 cases of non-recurrent laryngeal nerve and related literature reviews were made to acknowledge its incidence, variant types and matters concerned during thyroid operations.
821 recurrent laryngeal nerves were anatomized during 2496 thyroid operations, from which 5 were confirmed to hold non-recurrent laryngeal nerves (0.61%). 3 patients were found to have non-recurrent laryngeal nerves during re-operation because of voice horse after the first operation which improved much after re-operation. The other two patients were recognized during the first operation. All 5 cases were not diagnosed preoperatively.
Non-recurrent laryngeal nerve, a rare anomaly, is very vulnerable during thyroid surgery. It is helpful to avoid injuring non-recurrent laryngeal nerve that identification of the non-recurrent laryngeal nerve and its types.
非返性喉神经是一种罕见的异常，它与迷走神经直接相连或不相连，横向穿过喉部，其返支直接发自迷走神经。本文探讨了非返性喉神经在甲状腺手术中的临床意义。通过对 5 例非返性喉神经病例的临床资料和相关文献复习，了解其在甲状腺手术中的发生率、变异类型及注意事项。
在 2496 例甲状腺手术中解剖了 821 条喉返神经，其中 5 例证实有非返性喉神经（0.61%）。3 例因第一次手术后声音嘶哑而在第二次手术中发现非返性喉神经，第二次手术后明显改善。另外 2 例在第一次手术中发现。所有 5 例均未术前诊断。
非返性喉神经是一种罕见的异常，在甲状腺手术中非常脆弱。识别非返性喉神经及其类型有助于避免损伤非返性喉神经。
