Thyroidectomy is the surgical removal of all or part of the thyroid gland. The thyroid is a butterfly-shaped gland located at the base of the neck.
The portion of the thyroid gland that is removed during this procedure depends on the reason for the surgery. If only part of the thyroid is removed (partial thyroidectomy), the thyroid may function normally after surgery. If the entire thyroid is removed (total thyroidectomy), daily thyroid hormone treatment will be needed to replace the natural function of the thyroid.
