显露喉返神经在甲状腺手术中的临床意义

目的 探讨甲状腺手术中常规显露喉返神经对于减少其损伤的临床意义.方法 770例全麻下行甲状腺手术患者,解剖显露喉返神经430例,未解剖显露喉返神经340例.比较两组患者神经损伤的发生率.结果 显露神经组430例中2例（0.47％）出现暂时性声音嘶哑,无永久性喉返神经损伤.未显露组340例中有8例（2.35％）出现喉返神经损伤,其中6例为暂时性损伤,2例为神经永久性损伤.组间比较差异有统计学意义（P＜0.05）.结论 甲状腺手术时显露喉返神经可明显降低喉返神经损伤的发生率.

Clinical significance of recurrent laryngeal nerve exposure during thyroidectomy

Objective To discuss the clinical significance of recurrent laryngeal nerve（RLN） exposure in thyroidectomy.Methods A total of 770 patients who received thyroidectomy under general anesthesia during the past 2 years were analyzed retrospectively,including 430 cases with RLN exposure and 340 cases without it.The rate of RLN injury was compared between the two groups postoperatively.Results In 430 cases with RLN exposure,2 patients（0.47％）had transient hoarseness but not permanent RLN injury.In 340 cases without RLN exposure,there were 8 cases （2.35 ％） of RLN injury,including 6 cases of transient paralysis and 2 cases of permanent damage.There were significant differences between the groups （P ＜ 0.05）.Conclusion RLN exposure can markedly reduce the occurrence of RLN injury during thyroidectomy.
