Goiter is a common disease in life and is usually treated by surgery. Traditional thyroid surgery requires a 6-10 cm long transverse incision in the neck, which leaves an unsightly surgical scar on the neck for life after surgery. The lumpectomy thyroidectomy uses advanced lumpectomy surgical instruments and ultrasonic knife to remove the thyroid lesion with no scar on the neck; at the same time, the magnification of the lumpectomy makes the identification of fine tissues more precise and the surgical excision more thorough, greatly reducing complications and recurrence rates. Lumpectomy thyroid surgery can treat: simple goiter, nodular goiter or with cystic hyperplasia, thyroid adenoma, primary or secondary hyperthyroidism, and thyroid cancer. Advantages of lumpectomy thyroid surgery: no surgical scars on the neck, good cosmetic effect, three small scars at the edge of the areola are very hidden. The operation is less bleeding, delicate and has less chance of complications.
