The neck is an exposed part of the human body and an indispensable part of human beauty. Thyroid disease is mostly benign, and young and middle-aged female patients are the main ones. With the development of society and the improvement of people’s living standards, these patients have higher requirements for the cosmetic effect of surgical incisions. To adapt to this change, the cosmetic treatment of thyroid surgery has been receiving attention from general surgeons. Minimally invasive thyroid surgery can be divided into two categories according to whether or not an incision is left in the neck: a small incision approach to the neck, which can be subdivided into lumpectomy-assisted small incision thyroidectomy represented by Micoli, non-lumpectomy small incision thyroidectomy and some other modified procedures such as lateral neck approach small incision thyroidectomy. The cosmetic results of these surgical approaches depend mainly on the length and location of the incision, and there is a certain amount of surgical paralysis in the anterior neck area after the operation, which improves the cosmetic results compared with the traditional incision, but is still unsatisfactory for some patients. Another type of minimally invasive thyroid surgery is mainly used in Asian countries and regions, where the surgical incision is transferred to a hidden part of the body, such as the anterior chest wall, areola or armpit, thus leaving no surgical palsy in the anterior neck area and achieving excellent cosmetic results. This type of surgery requires a larger separation of the flap to create the surgical space, and the tissue trauma caused by the separation may be greater than that of traditional surgery. The following are some of the advantages of the lateral collateral approach to thyroid surgery with an oblique incision on the clavicle: 1. The incision is small, accounting for 1/3 to 1/2 of the original classical incision, which is in line with the principle of minimally invasive surgery, and the neck is in good shape. 2.No excessive freeing of the cervical flap, little tissue damage, light scar adhesions in the surgical area, no or slight swallowing sensation. 3.Small incision in the anterior paracervical approach does not require special equipment and special training. 4.It can help to protect the exposed blood vessels in the neck and stop the bleeding by compressing the jugular artery urgently if there is intentional bleeding during the operation. 5.If the tumor recurs in the contralateral gland lobe after surgery, the adhesions of the second surgery will be light, which is conducive to the surgical dissection of the contralateral gland lobe.
