Objective To investigate the injury of recurrent laryngeal nerve in thyroid surgery and to find a safer surgical method to avoid nerve injury. Methods The clinical data of 298 cases of Sub-total resection Near total resection or total resection of thyroid gland from December 2013 to December 2016 were collected,of which 170 cases of recurrent laryngeal nerve(exposure group) were revealed and 128 cases of recurrent laryngeal nerve(non-exposure group) were not revealed. The incidence of recurrent laryngeal nerve injury in two groups was analyzed,and the causes of recurrent laryngeal nerve injury were analyzed. Results The injury rate of patients with recurrent laryngeal nerve was 5.3% during the operation and 5.5% during the operation. There was no statistical difference between the two(P>0.05);During the operation,there were 30 cases of thyroid cancer in the recurrent laryngeal nerve group,all of which underwent radical surgery for thyroid cancer. The radical rate of thyroid cancer was 100%. During the operation,24 cases of thyroid cancer in the recurrent laryngeal nerve group were not revealed,of which 6 were Lymphatic node clearance and 18 were unperformed lymph node clearance,thyroid cancer radical rate of 25%,The difference between the two is statistically significant(P<0.05). Conclusion The exposure of recurrent laryngeal nerve did not increase the injury rate of recurrent laryngeal nerve. The exposure of recurrent laryngeal nerve is conducive to the protection of recurrent laryngeal nerve under direct viewing,so that the scope of thyroid cancer resection is more complete,ensuring the root cure of thyroid cancer.
