Thyroidectomy

aka total thyroidectomy, hemithyroidectomy, lobectomy of the thyroid, prophylactic thyroidectomy

Removing all (total) or half (hemi-) of the thyroid gland, after which thyroid hormone tablets replace its function.

The main treatment for differentiated thyroid cancer, followed by radioiodine when risk warrants it. Hemithyroidectomy is now adequate for low-risk tumours under 4 cm, and active surveillance is accepted for papillary microcarcinomas. Prophylactic thyroidectomy in childhood prevents medullary thyroid cancer in germline RET carriers (MEN2). Risks are voice change (recurrent laryngeal nerve) and low calcium (parathyroid injury).
