Transoral approach using the floor of the mouth to resect submandibular gland has
been in practice since a long time; however, the clinical application of the vestibular approach
is a relatively novel approach. As per my knowledge, the vestibular approach has only been
implemented to resect the thyroid gland , with the clinical application of transoral transvestibular
endoscopic approach in the surgical removal of the thyroid gland being reported for the first
time by Wilhelm et al.1 Transoral endoscopic thyroidectomy vestibular approach (TOETVA) is
currently in use in various institutions. TOETVA has been proposed, introduced and clinically
performed in various countries including South Korea, Thailand, India, China, Taiwan,
Singapore, USA, Mexico, Japan, Ecuador and Italy.1-4 We present our opinion on the clinical
procedure of TOETVA. The surgical procedure is carried out using a three-port technique at the
oral vestibule, by placing one 10-mm port for a 30° endoscope and two additional 5-mm ports
for the dissecting and coagulating instruments. CO2
insufflations pressure is maintained at 6
mmHg. An anterior cervical sub-platisma space is created from the oral vestibule down to the
sternal notch, lateral to the sternocleido muscles. Thyroidectomy is performed endoscopically
using conventional endoscopic instruments and intraoperative neuromonitoring (IONM)
