The neck is an important part reflecting the beauty of the human body. Traditional thyroid surgery leaves obvious scars on the neck, which seriously affects the aesthetics. With the development of laparoscopic surgery, a surgical procedure that can remove the tumor without affecting the aesthetics of the neck has emerged —— laparoscopic thyroid surgery. Its advantage is that the neck incision is tiny or the incision is designed in a hidden place, and the scar is almost invisible or absent in the neck with excellent cosmetic effect. Since the late 1990s, laparoscopic thyroid surgery has been widely used around the world. In China, this technology has been developed faster because of the large population and the high relative prevalence of thyroid disease, and it is increasingly accepted because of its concealed surgical incision (incision size 0.5-1CM in the thoracic breast area), small scar, and fast postoperative recovery. Our hospital has carried out lumpectomy thyroid surgery since 2005 and has achieved considerable success so far. The current indications include: unilateral or bilateral benign adenomas, cysts and nodules; hyperthyroidism with normal or mildly enlarged gland size; papillary thyroid carcinoma less than 1 cm in diameter with no invasion of the gland surface and no enlarged lymph nodes next to the central group carotid artery, etc.
