Abstract
PURPOSE: The transoral endoscopic thyroidectomy vestibular approach (TOETVA) has emerged as a new treatment option for patients with selected thyroid disease requiring surgery. The aim of this pictorial essay is to illustrate the healing outcomes of the vestibular incisions. METHODS: TOETVA patients were recruited at two Centers in China and Italy. TOETVA is initiated with one 10-20-mm median incision in the center of the oral vestibule 10 mm above the inferior labial frenulum, and two 5-mm lateral incisions, just below the lower lip near the labial commissure. Healing of the vestibular incision was monitored through serial photographs 1, 3, 7, 30, and 90 days after surgery. Outcomes were evaluated by Landry's score, time to healing, issues affecting wound outcomes, scar, fibrin, granulation, necrotic tissue formation, and infections. RESULTS: Results of TOETVA were monitored in 52 patients. There were no postoperative infections. All lateral incisions demonstrated favorable surgical outcomes. Landry's criteria scores indicated worse outcomes for the median incisions vs. the lateral ones (p<0.05). Median incisions healed well in 65.4% of patients, but 34.6% of patients had visible scars from the median incision 90 days after surgery. Eight (15.4%) had cicatricial diathesis, seven (13.5%) experienced displacement of the stitches, and three (5.8%) developed synechia with gingiva. When the central vestibular incision was <10mm from the gingiva, patients tended to form synechia (60%). There were no significant differences in wound healing between the Chinese and Italian patients. CONCLUSIONS: Knowledge of vestibular incision healing is essential to provide practical TOETVA clinical guide and to define optimal outcomes evaluation for transoral surgeons. Vestibular wound problems were confined only to the central incision.
