目的 探析显露喉返神经技术在高风险甲状腺手术中的临床价值。方法 临床选择2015年1月-2016年12月本院收治进 行高风险甲状腺手术病人100例，根据手术中有无喉返神经显露进行分组，分为显露神经组(n=60例)和未显露神经 组(n=40例)，比较两组的住院成本、手术时间、术中出血量等临床指标；比较两组出现喉返神经受损、低钙血症等 术后不良反应情况的发生。结果 显露喉返神经组的住院成本、手术时间、术中出血量等临床指标显著优于未显露 神经组，差异有统计学意义(P<0.05)；显露喉返神经组发生低钙血症2例(3.3%)，未显露喉返神经组10例(25.0%)， 两组比较差异显著(P<0.05)；显露喉返神经组出现喉返神经暂时性受损3例(5.0%)，永久性受损3例(5.0%)，未显露 喉返神经组出现喉返神经暂时性受损8例(20.0%)，永久性受损6例(15.0%)，两组比较差异显著(P<0.05)。结论 显 露喉返神经技术应用于高风险甲状腺手术中高度微创，住院成本低，可降低术后发生低钙血症、降低喉返神经的受 损，临床效果确切，值得临床推广。

Objective To explore the clinical value of exposing recurrent laryngeal nerve in high-risk thyroid surgery. Methods 100 cases of patients with high-risk thyroid surgery received and admitted to our hospital from January 2015 to 2016 December were selected clinically and divided into exposing nerve group (n=60 cases) and non-exposing group (n=40 cases) by having exposing recurrent laryngeal nerve or not in the operation to compare the clinical indexes of hospitalization cost, operation time, intraoperative bleeding, etc. and the postoperative adverse reactions of recurrent laryngeal nerve injury, and hypocalcemia, etc. in two groups. Results The hospitalization cost, operation time and intraoperative blood loss of exposing nerve group were significantly higher than those of non-exposing nerve group and the difference was statistically significant (P<0.05). The incidence of hypocalcemia was 2 in exposing nerve group (3.3%), and was 10 cases (25.0%) in non-exposing nerve group . There was significant difference between two groups (P<0.05). The appearance of transient damage recurrent laryngeal nerve was 3 cases (5.0%) and permannent damage was 3 cases in exposing nerve group and were 8 cases (20%) and 6 cases (15%) respectively in non-exposing nerve group. There was significant difference between two groups (P<0.05). Conclusion The application of exposing recurrent laryngeal nerve in high-risk thyroid surgery is highly minimally invasive with low hospitalization costs and can reduce the postoperative damage of calcemia and recurrent laryngeal nerve with clear clinical effect so that it is worthy of clinic promotion.
