甲状腺手术显露喉返神经的临床研究

Clinical study on exposure of recurrent laryngeal nerve during thyroid surgery

目的探讨甲状腺手术时显露喉返神经(RLN)对预防RLN损伤的作用。方法分析810例甲状腺手术中252例甲状腺手术中显露RLN(甲组)和558例术中未显露RLN(乙组)患者的临床资料。结果虽然甲组甲状腺手术切除范围大于乙组;但甲组RLN损伤发生率(1.19%)明显低于乙组(3.05%)(P<0.01)。结论甲状腺手术时有选择地显露喉返神经,可明显降低喉返神经损伤发生率。

Objective To explore the effect of exposure of the recurrent laryngeal nerve （ RLN ） in prevention of RLN injury during thyorid surgery. Methods The clinical data of 810 cases of thyroid operation in which the RLN was exposed in 252 cases （group A） and was unexposed in 558 cases （group B） were analyzed. Results Although the extent of thyroid resection was greater in group A than in group B, the rate of RLN injury in group A （1. 19 %） was significantly lower than that of group B （3. 05 % ,P 〈 0. 01）. Conclusions Selective exposure of RLN during thyroid surgery can significantly decrease the rate of RLN injury.
