Surgical Steps of Gasless Transaxillary Endoscopic Thyroidectomy: From A to Z.

In the past 30 years, the incidence of differentiated thyroid cancer (DTC) has been increasing rapidly and has become one of the most common malignant tumors in females. Currently, the main surgical treatment for DTC is standard open thyroidectomy (SOT) via a traditional Kocher mid-cervical incision, but postoperative neck scarring was associated with significantly worse health-related quality of life (HRQOL) scores. To offer better cosmesis, robotic/endoscopic thyroidectomy via cervical, axillary, anterior chest, breast, postauricular, or transoral approaches have been developed over the past 20 years. In general, gasless transaxillary endoscopic thyroidectomy (GTET) has advantages in terms of convenience, clarity of vision, and aesthetic incision. The current work aims to provide a step-by-step description of GTET, supported by a high-quality, pictorial guide.
