摘要
目的:探讨在甲状腺全切术中喉返神经喉外分支的变化。方法:回顾性分析108例显露颈段喉返神经的甲状腺全切手术患者的资料。结果:解剖喉返神经216根,其中20根存在分叉变异,分叉率为9.26%。且分叉比例左侧高于右侧。结论:喉返神经入喉前存在分叉变异,虽然较国外发生率低,但亦应引起重视,减少神经损伤的可能。
Objective：To explore the extralaryngeal furcation variation of the recurrent laryngeal nerve（RLN）in total thyroidectomy.Method：The clinical data of 216 RLNs from 108 patients undergone total thyroidectomy were retrospectively analyzed.Result：RLN was found during every operation and exposed in whole course until access into larynx.Twenty（9.26%）pieces of RLNs showed bifurcated or trifurcated RLNs before access into larynx.Ratio of furcation is lower than that reported before internationally.Bifurcations of RLNs on the left were more than that on the right.Conclusion：The protection of RLN is important for thyroid operation,especially in total thyroidetomy.Variation of extralaryngeal furcation of RLN usually leads to injury of RLN.Understanding of variation of RLN could decrease nerve function related complication.
