Abstract: ［Abstract］ Objective To investigate the feasibility and safety of endoscopic thyroidectomy via oral vestibular approach for thyroid cancer. Methods The clinical data of endoscopic thyroidectomy via oral vestibular approach were analyzed retrospective， including basic information of patients， operation procedures， operation time， bleeding volume， complications， hospital stay， and pathological results. Results From November 2016 to November 2018， 36 patients underwent endoscopic thyroidectomy via oral vestibular approach， including 27 females and 9 males， with a median age of 27 years （22-32 years）. All patients were successfully treated withradical thyroidectomy via oral vestibular approach （thyroidectomy and isthmus+lymphadenectomy of central region of affected side）， with an average operation time of 150 min （120-180 min）. The average amount of bleeding during operation was 35 ml （20-75 ml）， and no complications were found，such as wound infection， bleeding， hoarseness， drinking cough， hand?foot twitching after operation. One case was punctured the submental skin during operation. All cases had different degrees of swelling of the lips and chin after operation， and disappeared after 7 days. Pathological results showed that 36 cases were papillary thyroid cancer. The average number of lymph nodes was 5.5 （3-11）|there were no scars on the body surface and oral vestibule 3 months after operation， and the patients were satisfied with the cosmetic effect. Conclusion Endoscopic thyroidectomy via oral vestibular approach is safe and feasible in selecting suitable cases. It has advantages in cosmetic effect and thorough lymph node dissection in central region.
