Abstract

Background

Surgical outcomes of patients with thyroid carcinoma who underwent transoral endoscopic thyroidectomy vestibular approach (TOETVA) versus transoral robotic thyroidectomy (TORT) were compared.

Methods

Patients who underwent TOETVA or TORT between July 2016 and February 2022 were retrospectively analyzed. TOETVA and TORT groups were propensity score-matched (1:1) based on age, sex, body mass index, surgical extent, tumor size, and presence of thyroiditis.

Results

A total of 185 patients underwent transoral thyroidectomy (142 TOETVA and 43 TORT). Final diagnoses consisted of 135 papillary and seven follicular thyroid carcinomas in the TOETVA group and 43 papillary thyroid carcinomas in the TORT group (p = 0.138). Mean operative time was shorter for the TOETVA group than the TORT group (106.3 vs. 158.9 min, p < 0.001), whereas mean hospital stay was longer for the TOETVA group than the TORT group (2.2 vs. 1.9 days, p = 0.031). After 1:1 propensity score matching, each group included 43 patients. Mean operative time was shorter in the TOETVA group than the TORT group (106.2 vs. 158.9 min, p < 0.001), whereas mean hospital stay was longer in the TOETVA group (2.3 vs. 1.9 days, p = 0.031). There was no significant difference in vocal cord palsy incidences between the groups (one transient, one permanent in the TOETVA group vs. none in the TORT group, p = 0.359). The learning curve was 71 cases for TOETVA and 25 cases for TORT.

Conclusion

TOETVA had shorter mean operative time, and TORT had shorter learning curve and shorter mean hospital stay. Surgeons should be familiar with the advantages and disadvantages of each procedure.
