喉返神经及其分支解剖特征在甲状腺手术中的临床意义

摘要

Objective:To explore the clinical significance of anatomizing recurrent laryngeal nerve (RLN) and its branches during thyroidectomy. Methods: One hundred and five sides of RLN anatomized during 95 cases of thyroidectomy were retrospectively analyzed. Results:Ninety seven sides (92.38％) of the 105 RLN anatomized bifurcated into the laryngeal branch and extra-laryngeal branch. Six sides(5.71％ ) of the RLN gave off one branch. Two sides ( 1.91％ ) of the RLN gave off three branches. The lengths of branches were 0.4 - 2.5 cm. One case had postoperatively transient hoarseness. Conclusions: There are branches and other anatomical features of the RLN. Correct identification and safe dissection of the RLN are essential in thyroid surgery.%目的:探讨喉返神经及其分支解剖在甲状腺手术中的临床意义.方法:对95例甲状腺切除术中观测的105侧喉返神经的有关资料进行回顾性分析.结果:97侧(92.38%)喉返神经入喉前分成前、后2支,1支入喉者6侧(5.71%),3支入喉者2侧(1.91%);分叉距入喉点0.4～2.5 cm;1例术后出现暂时性声音嘶哑.结论:喉返神经存在着分支等解剖特点,术中正确辨认并安全地解剖喉返神经是避免喉返神经损伤的关键.
