Primary Hyperparathyroidism: Part Two: Surgical Management.

Primary hyperparathyroidism (PHPT) is caused by the overproduction of parathyroid hormone by 1 or more parathyroid glands resulting in hypercalcemia and its downstream clinical consequences. The definitive management of PHPT is surgery. Approaches to successful surgery include bilateral exploration or focused parathyroidectomy with intraoperative parathyroid hormone monitoring, which in experienced hands are both associated with a low risk of complications.
