The main treatment for thyroid cancer is surgery, but nuclear medicine and endocrine therapy can also improve the results of thyroid cancer surgery. There are two types of surgical procedures: open surgery and minimally invasive surgery. Open surgery is to make a 4-5 cm long incision on the top of the chest and open the middle of the cervical oblique muscle, after which the thyroid tissue can be seen. After the supraglottic nerve is revealed and the parathyroid nerve and parathyroid glands are protected, the surgeon begins to carefully separate the periphery of the thyroid gland. First, the thyroid gland is removed, and if the thyroid gland is reported to be malignant, the lymph nodes on the side of the thyroid gland are cleared. If the lymph nodes are more metastatic, the lateral cervical lymph nodes should also be cleared. Of course, in the process of searching for nerves, the supraglottic nerve is sometimes not easy to find, so it is possible to avoid it. Another type of minimally invasive or cosmetic thyroid surgery is called lumpectomy, which includes axillary approach, thoracic breast approach, and transoral approach, depending on the approach. The lumpectomy makes the incision from the distal side and the other steps are similar.
