[Clinical outcomes of transoral endoscopic thyroidectomy vestibular approach assisted with submental mini-incision for early thyroid papillary carcinoma].

To investigate the efficacy of transoral endoscopic thyroidectomy vestibular approach (TOETVA) assisted with submental mini-incision in early thyroid papillary carcinoma. A total of 63 patients with early papillary thyroid carcinoma (cT1N0M0) were included who underwent TOETVA from December 2019 to May 2021 in Department of Thyroid Surgery of the Affiliated Hospital of Jining Medical University. There were 4 males and 59 females, aged from 17 to 46 years old. Of those 36 patients received traditional TOETVA as control and 27 patients accepted modified TOETVA assisted with submental mini-incision. The clinical outcomes of patients in two groups were compared. Chi-square test and test were used in statistical analyses. Compared to control group, modified TOETVA group had the less mean operation time [(146.63±38.62) minutes . (167.78±36.71) minutes, =-2.21, =0.031], the shorter time required for returning to normal diet after operation [(2.11±0.89) days . (2.72±1.16) days, =-2.28, =0.026], and the lower probability of mandibular numbness (0 . 16.67%, χ=4.97, =0.026). There was no significant difference between two groups in intraoperative blood loss, postoperative drainage volume, number of central lymph nodes dissection, and postoperative complications such as gas embolism, postoperative bleeding, postoperative infection, skin burns, subcutaneous effusion and so on(all >0.05). After 6 months of operation, the thyroid ultrasound of the patients in two groups showed no recurrence, and the patients were satisfied with their surgical incision appearances. Both the modified and traditional TOETVA show similar efficacies for treatments of early thyroid papillary carcinoma, but the modified TOETVA can reduce the operation time and improve the quality of life.
