Exploring the feasibility of using endoscopic thyroidectomy via oral vestibular approach (TOETVA) without placement of drainage in patients with stage cT_1-2N₀ papillary thyroid carcinoma (PTMC).

A prospective study was conducted on 86 cT_1-2N₀ stage PTMC patients who visited from January 2020 to May 2023. The patients were randomly divided into two groups using a random number table method, with 43 patients in each group. All patients received TOETVA treatment. Group A did not place drainage after TOETVA surgery, while Group B placed drainage. Use SPSS 22.0 software for analysis, use () to represent perioperative related indicators and other quantitative data, and perform independent sample t test for inter group comparison; Using [examples (%)] to represent postoperative complications and other counting data χ² Inspection. P<0.05 indicates a statistically significant difference.

Compared with group B, the thyroid bed fluid volume and postoperative satisfaction score of group A patients were significantly increased, and postoperative hospitalization time, cost and Visual Analogue Scale (Visual Analogue Scale, visual analogue scale, visual analogue scale) were significantly increased. VAS score and sleep quality on the day of operation decreased significantly with the Pittsburgh Sleep quality index (PSQI) score, and the difference was statistically significant between the three groups (P<0.05). There was no significant difference in other indexes between the two groups (P>0.05).

It is safe and feasible for cT_1-2N₀ PTMC patients to not place drainage after TOETVA, without increasing the risk of postoperative complications, reducing hospitalization time and costs, and ensuring clinical safety and effectiveness.
