甲状腺手术中常规解剖喉返神经的临床价值

Clinical value of designed dissection of recurrent laryngeal nerve in thyroid surgery

目的探讨甲状腺手术中常规解剖喉返神经对防止其损伤的临床价值。方法回顾性分析5344例甲状腺手术患者在全身麻醉下行手术治疗的临床资料,术中解剖喉返神经548例(解剖组),未解剖喉返神经4796例(未解剖组);比较两组术中喉返神经损伤的发生率有无差异。结果解剖组喉返神经损伤12例,发生率为2.2%;未解剖组喉返神经损伤512例,发生率为10.7%。两组喉返神经损伤率差异具有统计学意义(P<0.01)。结论甲状腺手术中常规解剖喉返神经能有效防止其损伤。

Objective To explore the value of dissecting the recurrent 1aryngeal nerve（RLN） in thyroid surgery to prevent RLN from injury.Methods Clinical data of 5344 cases of thyroidectomy under general anesthesia was analyzed retrospectively.Among these cases,548 underwent dissection of the RLN（RLN dissecting group）,and 4796 did not（non-RLN dissecting group）.The difference of the RLN injury rates between the two groups was analyzed.Results RLN injury occurred in 12 cases of the RLN dissecting group（RLN injury rate =2.2%） and in 512 cases of the non-RLN dissecting group（injury rate=10.7%）.The difference of RLN injury rates between the two groups was statistically significant（P0.01）.Conclusion Dissecting RLN in the thyroid surgery is an effective step to prevent the nerve from injury.
