Protection Effect of Neural Detection Technique on Recurrent Laryngeal Nerve in Second Surgery for Thyroid Carcinoma
Objective To explore the protection effect of neural detection technique on recurrent laryngeal nerve(RLN)in second surgery for thyroid carcinoma(TC).Methods A retrospective analysis was performed on the case data of 76 patients with TC recurrence who underwent secondary surgery in Cervical Thyroid Surgery Department of Nanyang Second People's Hospital between January 2018 and October 2022.According to specific intraoperative protection methods for RLN,they were divided into group A(42 cases)and group B(34 cases).On basis of endoscopic radical resection of TC,group A was given intraoperative neural detection technique,while group B was given routine RLN exposure.The operation time,intraoperative blood loss,exploration time of RLN,success rate of intraoperative RLN identification,postoperative drainage volume,hospitalization time,incidence of paradoxical vocal cord motion at 1 day,1 week and 3 months after surgery,scores of voice handicap index[voice handicap index(VHI),including function(F),physiology(P)and emotion(E)]and occurrence of recurrent laryngeal nerve injury(RLNI)at 3 months after surgery were compared between the two groups.Results The operation time,RLN exploration time and removal time of postoperative drainage in group A were shorter than those in group B,intraoperative blood loss was lesser than those in group B(P＜0.05).The success rate of intraoperative RLN identification in group A(100.00％)was higher than that in group B(82.35％)(P＜0.05).At 1 day and 1 week after surgery,incidence rates of paradoxical vocal cord motion in group A were lower than those in group B(P＜0.05).At 3 months after surgery,there was no significant difference in the incidence of paradoxical vocal cord motion between the two groups.At 3 months after surgery,scores of F,P and E in group A were lower than those in group B(P＜0.05).The total incidence of RLNI in group A(7.14％)was significantly lower than that in group B(29.41％)(P＜0.05).Conclusion The neural detection technique can ensure the functional integrity of RLN and reduce the incidence of RLNI in second surgery for TC,with significant clinical effect.
