显露喉返神经在复发性结节性甲状腺肿再手术中的应用

Application of recurrent laryngeal nerve exposure in recurrent nodular goiter reoperation

目的探讨显露喉返神经（RLN）在复发性结节性甲状腺肿再手术的作用。方法回顾性分析我院头颈科2011年1月～2015年6月期间再次手术治疗的64例复发性结节性甲状腺肿患者的临床资料，按有无显露RLN分成显露RLN组35例．未显露RLN组29例，比较两组RLN损伤的差异。结果64例复发性结节性甲状腺肿再次手术中，显露RLN组出现暂时性RLN损伤1例，损伤率2．9％；未显露RLN组出现RLN暂时性损伤3例，RLN永久性损伤1例，损伤率13．8％。两组间RLN损伤率比较差异有统计学意义（P〈0．05）。结论复发性结节性甲状腺肿再次手术时．显露RLN能有效降低RLN损伤率。

Objective To discuss the effect of recurrent laryngeal nerve （RLN） exposure in recurrent nodular goiter reoperation. Methods Clinical materials of 64 patients with recurrent nodular goiter who were given reoperation in our hospital from January 2011 to June 2015 were reviewed and divided based on RLM exposure into exposure group （35 cases） and non-exposure group （29 cases）. The differences in RLN injuries were compared between two groups. Results Of the 64 cases of recurrent nodular goiter reoperation, there was 1 case （2.9%） of RLN injury in the exposure group, and there were 3 cases of RLN transient injury and 1 case of RLN permanent injury（13.8%） in the non-exposure group, which was significantly different between two groups（P〈0.05）. Conclusion Exposure of RLN in recurrent nodular goiter reoperation can effectively reduce the injury rate of RLN.
