Abstract
Since 2018, transoral endoscopic thyroidectomy vestibular approach (TOETVA) has emerged as a true scarless thyroid surgery. In this study, we explore early outcomes and learning curve of this new approach. A retrospective cohort including conventional thyroidectomies and TOETVAs performed in a cancer center was designed. Learning curve and early surgical outcomes of TOETVA were assessed and compared to conventional thyroidectomy. A total of 56 TOETVAs and 745 conventional thyroid procedures were included. In the TOETVA group, we had a 14.4% total complication rate with no permanent vocal cord paresis or hypocalcemia. The mean surgical time dropped from 167 to 117min (p=0.0001) after the 15 first cases. Comparing to conventional procedures, we didn't find any significant difference in complications rate. Operative time was longer in the TOETVA group. In this study, TOETVA was safe and feasible, with a learning curve of 15 cases.
