What is parathyroidectomy and what are the indications for parathyroid surgery?
Parathyroidectomy is an operation in which one or more parathyroid glands are removed. This operation is performed to control hyperparathyroidism (overactivity of the parathyroid glands) which is either caused by a benign tumour of one or more of the glands (parathyroid adenoma), or generalized growth and overactivity of all of the glands (parathyroid hyperplasia). In rare instances, surgery is performed on the parathyroid glands in order to remove a parathyroid cancer.
