Endoscopic techniques used to surgically remove the thyroid gland are minimally invasive and the scars are totally invisible. The safety of the operation lies on the quality of the images captured on the endoscopic high-definition camera. Also, it depends upon the types of thyroidectomy that is undertaken. There is total thyroidectomy which involves the surgical removal of the whole gland. Near-total thyroidectomy involves the surgical removal of both the lobes except for a small amount of thyroid tissue. Subtotal thyroidectomy leaves 3‑5 g of the tissue on the less affected side of the gland.
