Traditional thyroid surgery requires a 6 to 10 centimeter long horizontal incision in the neck, leaving an unsightly scar on the neck for the rest of the patient’s life. With the development of science and technology, there is already a way to leave no scar on the neck after surgery. Lumpectomy is a new high-tech technique developed in recent years, which makes a small incision of 1 cm between the patient’s two breasts, and small incisions of 1 cm and 0.5 cm at the edge of areola of the two breasts, respectively, and removes the thyroid gland by using the advanced luminal surgical instruments and ultrasonic knife to minimize and hide the surgical incision, so as to achieve a better result. The surgical incisions are miniaturized and hidden to achieve aesthetic and minimally invasive results. Advantages of Lumpectomy Thyroid Surgery: 1. No surgical scars on the neck, good cosmetic effect. It only leaves a small 1 cm long scar between the two breasts, and the two small scars at the two nipples are basically invisible; 2. Less bleeding, delicate operation, and less chance of complications; 3. Less trauma, and quicker postoperative recovery for the patient. Which patients are suitable for laparoscopic thyroid surgery? Simple goiter; 2. Nodular goiter or with cystic hyperplasia; 3. Thyroid adenoma; 4. Primary or secondary hyperthyroidism within II degree of enlargement.
