he parathyroid glands are also located in the neck and control the level of calcium in the bloodstream by secreting parathyroid hormone.

When patients have hyperparathyroidism their calcium is elevated and this can be treated by parathyroidectomy.

Parathyroidectomy usually involves removal on one parathyroid gland in primary hyperparathyroidism or all four glands in secondary hyperparathyroidism, a condition affecting patients with renal failure.

In primary hyperparathyroidism if the causative gland can be located preoperatively with the use of a Sestamibi (a nuclear scan) and Ultrasound scan then surgery can be performed via a Minimally Invasive approach through a 2 cm incision on one side of the neck. This surgery usually requires overnight admission.
