At present, the thyroid surgery we perform can be divided into the following three types of surgery: 1. Conventional incision thyroid surgery: a 5CM curved incision in the lower anterior neck to complete the thyroid surgery. 2.Lumpectomy-assisted thyroid surgery: 2CM curved incision in the lower part of the anterior neck to complete the thyroid surgery with the assistance of lumpectomy. Limited to thyroid masses of 3CM or less. There is only a 2CM scar on the neck, which is basically invisible. 3.Thoracic breast approach with full lumpectomy: The thyroid surgery is performed through the subcutaneous tunnel above the breast and in front of the chest to reach the thyroid area. It is limited to masses under 3cm. There is no scar on the neck at all. 4. Surgery for thyroid cancer: Surgery for thyroid cancer requires total excision of the affected side, isthmus excision, and subtotal excision of the contralateral side, plus at least lymph node dissection of the central group on the affected side. At present, lumpectomy for thyroid cancer is still in the exploratory stage. 5. Parathyroid surgery: At present, we have developed an intraoperative isotope-guided localization method to explore the parathyroid glands, which has greatly improved the accuracy of parathyroid gland exploration and reduced the possibility of missing parathyroid glands.
