Transoral endoscopic thyroidectomy vestibular approach with intraoperative nerve monitoring

Abstract

Background: Transoral endoscopic thyroidectomy by a vestibular approach (TOETVA) is a novel technique for thyroid gland excision. Compared to the transaxillary endoscopic and bilateral axillo-breast approaches, which require substantial dissection to reach the thyroid gland, TOETVA provides the most direct access to the target organ. Methods: The aim of this video is to provide a step-by-step overview of TOETVA and demonstrate how to set up and utilize intraoperative nerve monitoring. Results: Three incisions are placed in the vestibular region of the oral cavity just below the lower lip for placement of 2 lateral 5-mm trocars and 1 centrally placed 11-mm trocar. Insufflation to 6 mm Hg is used to maintain the working spacing. Using a 2-handed technique and triangulation, the thyroid gland is mobilized, taking care to identify and preserve the relevant cervical anatomy. Conclusion: TOETVA is safe and feasible and provides an excellent cosmetic outcome with the most confidentially compared to the other remote access endoscopic approaches.
