“喉返神经显露”在甲状腺手术中避免神经损伤的作用

The effect of the exposure of recurrent laryngeal nerve on avoiding nerve injury during thyroid operation

目的探讨"喉返神经显露"在甲状腺手术中避免神经损伤的作用。方法回顾分析416例甲状腺手术病例资料,其中显露喉返神经组290例,未显露喉返神经组126例;比较分析术后喉返神经损伤情况。结果显露喉返神经组仅2例(0.69%)出现术后暂时性喉返神经损伤;未显露喉返神经组术后4例暂时性损伤、1例永久性损伤,总损伤率3.97%。术中显露喉返神经后发生神经损伤的几率明显降低(P<0.05)。结论在甲状腺手术中常规显露喉返神经可有效降低喉返神经损伤的发生率。

Objective To investigate the effect of the exposure of recurrent laryngeal nerve on avoiding nerve injury during thyroid operation.Methods 416 patients with thyroid diseases who were performed the surgical treatment were analyzed retrospectively,in which 290 cases who were operated through exposing the recurrent laryngeal nerve were regarded as exposing group,and the rest were regarded as the group without exposure.The recurrent laryngeal nerve injury after operation was analyzed postoperatively.Results The transient recurrent laryngeal nerve injury occurred only in one case of the exposing group（0.69%）.Three cases of transient recurrent laryngeal nerve injury and one case of permanent recurrent laryngeal nerve injury were found in the group without exposure in which the total injury ratio was 3.97%.The recurrent laryngeal nerve injury ratio in the exposing group decreased significantly（P0.05）.Conclusion Exposing recurrent laryngeal nerve during routine thyroid operation can reduce the recurrent laryngeal nerve injury effectively.
