Thyroid gland

Thyroidectomy is the removal of all or part of your thyroid gland. Your thyroid is a butterfly-shaped gland located at the base of your neck. It produces hormones that regulate every aspect of your metabolism, from your heart rate to how quickly you burn calories.

Thyroidectomy is used to treat thyroid disorders, such as cancer, noncancerous enlargement of the thyroid (goiter) and overactive thyroid (hyperthyroidism).

How much of your thyroid gland is removed during thyroidectomy depends on the reason for surgery. If only a portion is removed (partial thyroidectomy), your thyroid may be able to function normally after surgery. If your entire thyroid is removed (total thyroidectomy), you need daily treatment with thyroid hormone to replace your thyroid's natural function.
