The neck also belongs to an important part of the appearance. Traditional thyroid surgery requires an incision in the neck, which has a major impact on the patient’s cosmetic outcome, and even the cosmetic sutures that are now commonly used do not completely eliminate the scar. Lumpectomy-assisted subclavian incision thyroidectomy is now well established and is particularly suitable for young women as it does not leave any scars on the neck. A 3-5 cm long incision is made under the clavicle, separating along the normal tissue space to the thyroid gland, and the diseased thyroid tissue is removed under the laparoscope, which is a combination of minimally invasive and cosmetic. After surgery, the incision is not exposed even if the patient wears low-necked, low-cut clothing in the summer. This procedure does not prolong the patient’s hospitalization and recovery time, and the total cost is comparable to that of traditional surgery, making it easy for patients to accept. It is mainly used for benign thyroid lesions up to 5cm, parathyroid adenomas and limited thyroid cancers.
