Abstract

The transoral endoscopic thyroidectomy vestibular approach (TOETVA) has excellent cos-metic effects and its popularity is increasing worldwide. We present our experience with TOETVA and its short-term outcomes. This study included 110 consecutive patients who underwent TOETVA at a single institution between July 2016 and June 2020. We analyzed clinicopathologic data, short-term postoperative outcomes, and learning curve using cumulative summation (CUSUM) analysis. Of the 110 patients who underwent TOETVA, 101 had malignant disease and 100 (90.9%) underwent lobectomy. The mean age was 39.7 ± 9.7 years, and the mean tumor size was 1.0 ± 0.7 cm (range, 0.3–3.6 cm). Operation time was 168.0 ± 63.4 min for total thyroidectomy, 111.0 ± 27.7 min for lobectomy, and 73.7 ± 18.1 min for isthmusectomy. Five patients (4.5%) experienced transient vocal cord palsy (VCP) and one (0.9%) had permanent VCP. The swallowing impairment index-6 score was 2.18 ± 3.21 at postoperative three months, and 0.97 ± 1.72 at postoperative six months. The learning curve for lobectomy was 58 cases in CUSUM analysis. TOETVA is a safe and feasible approach with an acceptable operation time and a low complication rate. This approach is a surgical option for patients who desire excellent cosmesis.
