Comparison of Transoral Robotic Thyroidectomy and Transoral Endoscopic Thyroidectomy via Vestibular Approach Using an Endoscopic Retractor: A Single-Center Experience.

Background/Objectives: The TOETVA and TORT have been successfully refined in recent years, with few complications and excellent results. In this study, we compared TORT and TOETVA in patients with papillary thyroid cancer. Methods: From September 2016 to January 2022, we retrospectively compared patient characteristics and clinical features from 100 TORT cases and 300 TOETVA cases, as well as their respective learning curves. Results: Median operation time of TORT was 80.4 min, similar to TOETVA (81.4 min, p = 0.719). Median docking time of TORT was 4.51 min and median console time was 27.72 min. The length of stay of TORT and TOETVA was 2.29 and 2.54 (p = 0.002). The median number of retrieved central lymph nodes for TOETVA and TORT were 2.89 and 2.99 (p = 0.746). Discussion: There was no significant difference with clinical features between TORT and TOETVA.
