There are open and lumpectomy thyroid surgeries. Open surgery leaves a scar on the neck, while lumpectomy is a cosmetic surgery that leaves no scar on the neck. The lumpectomy thyroid technology overturns the traditional open thyroid surgery concept by making a small incision from the hidden part of the body to reach the neck and using ultrasonic knife to remove the thyroid gland under the magnification of the lumpectomy, which is a perfect combination of surgery and computer science, optics, mechanics and other multidisciplinary. Advantages of lumpectomy thyroid surgery: 1. aesthetic appearance, no scars on the neck; 2. magnification of the lumpectomy, proper brightness and flexible viewpoint, so that structures such as blood vessels and nerves are more clearly visible; 3. fast recovery and short hospital stay. Indications for surgery: 1. nodular goiter and thyroid adenoma; 2. hyperthyroidism; 3. early differentiated thyroid cancer; 4. thyroglossal cyst; 5. parathyroid adenoma
