Minimally invasive thyroid surgery means that the surgical incision is made in the chest and the thyroid is operated on by introducing a micro-scalpel and endoscope into the thyroid area through the skin. There is no scar on the neck because the incision is made on the chest, but there are at least two scars on the chest that are not very large. Since women use bras to hide the scars, this surgical method is popular among women. At the same time, the magnification effect under the lumpectomy and clearer vision can well avoid intraoperative complications, so there will be less complications for surgeons who are skilled in lumpectomy. Our department has performed more than 500 such surgeries, and the results have been well documented to be superior to open thyroid surgery, and complications are much less common. Minimally invasive thyroid surgery has many advantages, but it has certain indications. It is generally accepted that the following cases are suitable for minimally invasive lumpectomy: benign nodules less than 6 centimeters in diameter with a solitary origin; early thyroid cancer without lymph node metastasis.
