Currently, the following types of incisions are more commonly used for minimally invasive thyroid surgery: 1. Transoral: an incision is made in the mouth for the operation and the resected tumor is removed from the mouth; 2. Transareolar: a 1 cm incision is made in the areola on the left and right of the woman for the main operation and the mass is removed along the main operation hole; 3. Transaxillary: an incision is made in the folds of the axilla for the main operation and the resected specimen is removed; 4. Thoracic breast approach: the main operation hole is made in the two areolas plus the front of the chest.
