In recent years, with the skillfulness of laparoscopic surgery and the continuous development of laparoscopic surgical instruments, the laparoscopic technique has been widely used in thyroid surgery. This technique can move the incision originally made in the neck to the outside of the neck, such as the chest, areola, armpit, etc., where a very small incision is made to create a tunnel from under the skin to reach the surgical site and remove the tumor. The biggest advantage is that the incision can be hidden, which is a cosmetic surgery in thyroid surgery. Establishment and maintenance of surgical spaceThe first step in laparoscopic thyroid surgery is to establish a surgical space between the superficial cervical fascia and the thyroid gland, and to maintain this space by insufflation (i.e., injecting CO2 into an artificial space in the neck and maintaining the pressure at 6-8 mmHg) to facilitate surgical operations. Choice of surgical approach Lumpectomy thyroid surgery in our hospital is usually done by transareolar or thoracic breast approach. Areola approach: three small incisions are made in both areolas, the larger one is located in the medial side of the right areola with a length of 1 cm, and the smaller one is located in the left and right areolas at about 11 o’clock, with a length of 0.5 cm. Thoracic breast approach: a 1.0 cm incision is made to the right of the bilateral nipple line in front of the sternum, a 5 mm curved incision is made in the inner and upper edges of the right and left areolas, and 5 mm puncture tubes are placed for the operation holes respectively. The advantages of this method are: (1) the operation space is larger, can be removed a larger diameter of the thyroid swelling. (2) Bilateral thyroid lesions can be treated at the same time. Indications for surgery (1) Thyroid adenoma. (2)Thyroid cysts. (3)Nodular goiter (single or multiple, preferably <5 cm in diameter). (4) Isolated toxic thyroid nodules. (5) Thyroid cancer without neck lymph node metastasis. Absolute contraindications to surgery (1) History of previous neck surgery. (2)Huge thyroid mass (diameter >5cm). (3) Rapidly developing malignant tumor with extensive lymph node metastasis. Relative contraindications to surgery include: (1) Previous history of neck radiation therapy. (2) Thyroiditis. (3) Hyperthyroidism. Through clinical practice, it has been proved that lumpectomy is a safe and feasible new procedure, and the range of indications for surgery has been gradually expanded, involving thyroid adenomas, nodular goiter, hyperthyroidism below the second degree of enlargement of the thyroid gland, and some early, low-grade malignant thyroid cancers, etc. The procedure includes partial resection of the thyroid gland and removal of the thyroid gland. Surgical procedures include partial thyroidectomy, unilateral lobectomy, bilateral subtotal resection, subtotal or total resection and central cervical lymph node dissection. That is to say, most of the traditional open thyroid surgeries can be successfully accomplished under laparoscopy, while its postoperative complications do not increase compared with the traditional open thyroid surgeries, and no surgical scar is left on the exposed parts of the body after the surgery, which achieves a more satisfactory cosmetic effect.
