Removal of half or all of the thyroid gland

The thyroid gland is a 5cm butterfly-shaped organ just beneath your Adam’s apple at the front of your neck. The thyroid gland releases thyroid hormone which is essential for your metabolism.

Your GP may refer you to an endocrine surgeon for the following reasons:

  • Thyroid lump/nodule or cancer

  • Goitre (enlarged thyroid gland)

  • Thyrotoxicosis (overactive thyroid)


Total thyroidectomy is an operation to remove the whole thyroid gland to treat these conditions.

Hemithyroidectomy removes one half of the thyroid gland and is performed to help diagnose certain thyroid lumps to rule out cancer.
