Abstract Objective: To investigate the application value of recurrent laryngeal nerve exposure in peroral total endoscopic thyroidectomy, so as to find a reliable surgical approach to reduce postoperative complications. Method: A total of 40 patients who underwent peroral total endoscopic thyroidectomy in the Second Affiliated Hospital of Gannan Medical College from January 2021 to April 2022 were selected. According to whether the recurrent laryngeal nerve was dissected or not, the patients were divided into the control group (thyroid lobectomy without recurrent laryngeal nerve dissection) and observation group (thyroid lobectomy after recurrent laryngeal nerve dissection), with 20 cases in each group. The occurrence and severity of postoperative hoarseness and recovery time of voice were compared between the groups, the operation time, intraoperative blood loss, postoperative wound recovery time, length of hospital stay and wound bleeding were recorded, postoperative recurrent laryngeal nerve injury was objectively evaluated. Result: The incidence of hoarseness in the observation group was significantly lower than that in the control group (P<0.05), the GRBAS grading of hoarseness assessment proposed by Japanese society for logopedics and phoniatrics was better than that in control group (P<0.05), and recovery time of voice was shorter than that in control group (P<0.05). The amount of intraoperative bleeding in the observation group was more than that in the control group, operation time was significantly longer than that in the control group (P<0.05), the postoperative wound bleeding was less than that in the control group (P<0.05), postoperative wound recovery time and length of hospital stay in the observation group were significantly shorter than those in the control group (P<0.05). There was a statistically significant difference in the total incidence of recurrent laryngeal nerve injury between the two groups (P<0.05). Conclusion: Recurrent laryngeal nerve exposure can improve the effect of peroral total endoscopic thyroidectomy. It can not only protect recurrent laryngeal nerve and reduce the incidence of hoarseness, but also shorten hospital stay and promote recovery, and can be widely used in thyroid surgery.
