The incision for general thyroid surgery is located in the middle of the neck, about 2 horizontal fingers above the sternoclavicular joint, in a curved transverse incision, 8-10 cm in length, which has a certain impact on cosmetology. Due to the increasing incidence and malignancy of thyroid disease in recent years, the number of patients requiring surgical treatment for thyroid disease is increasing, especially in young and middle-aged women. Due to concerns about the larger thyroid surgical incisions, it is a great pity that we often encounter patients who delay treatment as a result in our clinical work. Therefore, more thyroid surgery patients could be benefited if the incision for thyroid surgery could be improved. With the improvement of surgical proficiency and anatomical knowledge, small incision thyroid surgery can be performed on patients with thyroid tumors less than or equal to 4 cm, including patients with thyroid cancer, where the incision can be no more than 4 cm. The advantages of small incision thyroid surgery are: it meets the cosmetic requirements of patients, reduces the trauma of surgery and facilitates recovery; at the same time, it can be performed under direct vision on At the same time, it is possible to perform central lymph node dissection for thyroid cancer patients under direct vision, which improves the thoroughness of the surgery. Generally, the incision of thyroid surgery is as thin as a line within one month, then it will gradually thicken from one month after surgery, and it will be raised from three months after surgery, reaching a peak at six months after surgery. The healing of thyroid surgery incisions is related to the good or bad alignment of the incision sutures and the individual’s physical condition, and is not related to the placement of drains.
