甲状腺手术中喉返神经的解剖特点观察及作用研究

The study of the effects and observation on anatomical characteristics of recurrent laryngeal nerve in thyroid surgery

目的:探讨甲状腺手术中喉返神经的解剖特点,以为手术及并发症的预防提供资料。方法:选取2007年1月～2010年1月进行甲状腺手术治疗的586例(678侧)患者为研究对象,分别研究其术中喉返神经的定位、分支及其与周围组织的关系,并对喉不返神经的发生率及并发症发生率等进行研究及比较。结果:经研究比较发现,586例患者中喉不返神经的发生率为0.74%,喉返神经损伤发生率为2.5%,喉返神经与周围组织的关系所占比例差异也较大,P均<0.05,差异均有统计学意义。结论:在甲状腺手术中解剖显露喉返神经对于降低并发症发生率,保护喉返神经,提高手术成功率作用较大,值得进一步研究及探讨。

Objective： To study the anatomical characteristics of recurrent laryngeal nerve in thyroid surgery,in order to provide data for the operation and prevention of complications.Methods： 586 patients who were treated with thyroid surgery from January 2007 to January 2010 were selected as research object,and the location,branches,relation with surrounding tissues of all the patients were studied,and the incidence of nonrecurrent laryngeal nerve and complications were studied and compared.Results： According to the results,the incidence of nonrecurrent laryngeal nerve was 0.74%,the incidence of recurrent laryngeal nerve injury was 2.5%,proportions of their relation with surrounding tissues were bigger,P〈0.05,there were significant differences.Conclusion： The effects of discovering the recurrent laryngeal nerve for decreasing incidence of complication,protecting recurrent laryngeal nerve and improving the surgical success rate in thyroid surgery is important,and it is worthy of further study and investigate.
