Thyroidectomy
What Is It?
Thyroidectomy is the surgical removal of part or all of the thyroid gland. This important gland, located in the lower front portion of the neck, produces thyroid hormone, which regulates the body's production of energy. A healthy thyroid gland is shaped like a butterfly, with right and left lobes connected by a bridge called the thyroid isthmus. Depending on the reason for a thyroidectomy, all or part of the thyroid gland will be removed. The various types of thyroidectomy include:
- Partial thyroid lobectomy (a rare procedure) — Only part of one thyroid lobe is removed.
- Thyroid lobectomy — All of one thyroid lobe is removed.
- Thyroid lobectomy with isthmusectomy — All of one thyroid lobe is removed, together with the section between the two lobes (called the thyroid isthmus).
- Subtotal thyroidectomy — One thyroid lobe, the isthmus and part of the second lobe are removed.
- Total thyroidectomy — The entire thyroid gland is removed.
A thyroidectomy may be performed by using a conventional surgical approach, by an endoscopic method done through smaller incisions, or by robotic assisted surgery.
