RESUMO
BACKGROUND: 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. METHODS: 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. RESULTS: 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 117 min (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. CONCLUSIONS: In this study, TOETVA was safe and feasible, with a learning curve of 15 cases.
