Abstract: Objective The clinical practice oftransoral endoscopic thyroidectomy vestibular approach（TOETVA） and its comparison with open thyroidectomy. Methods The clinical data of 90 patients of thyroidectomy from March 2019 to December 2019 werecollected and retrospectively analyzed in the Ningbo Huamei hospital, Chinese Academy of Sciences,Department of thyroid surgery. The patients were assigned to TOETVA（45 cases） and conventional open thyroidectomy （the sample size of patients with traditional openthyroidectomy is large, 45 cases were selected by random sampling）, the gender, age, BMI, pathological type, cleaning the number of lymph nodes, and the operative time, postoperative drainage,postoperative complications and associated long-term prognostic indicators were compared. Results There was no statistically significant difference between the two surgical procedures in preoperative and postoperative clinical data,and there was no significant difference in intraoperative indicators such asbleeding volume and lymphatic dissection between the two groups. Butcompared with the open group, the intraoperative operation time was longer （P<0.05）, the operation cost was moreexpensive, and the length of hospitalization time was shorter. Conclusion TOETVA is safe and feasible in selecting suitable patients. It has advantages in cosmetic effect.
