"Three-propulsion" suspension method for endoscopic thyroid surgery gasless axillary approach.

Gasless endoscopic thyroidectomy through unilateral axillary approach has advantages of clear vision, simple manipulation, short learning curve, hidden surgical incision, no postoperative neck scar, and less swallowing discomfort. During the procedure the separation path goes through thoracic muscle surface, sternocleidomastoid gap and jugular vein, which may meet various variations of neck muscles, blood vessels and nerves. With the "three-propulsion" suspension cavity construction method the procedure advances the dissection from the axillary incision to clavicle, from the clavicle to sternocleidomastoid gap and from the sternocleidomastoid gap to thyroid. Combined with intraoperative hanging upward hook it can establish a good cavity for the subsequent surgical operation. This article introduces the main steps, key points and attentions of the "three-propulsion"suspension cavity construction method in gasless endoscopic thyroidectomy through unilateral axillary approach.
