A parathyroidectomy is a surgery to remove parathyroid glands. There are four parathyroid glands located in the neck. The glands make a hormone that balance the level of calcium in the blood.

The surgery is done to remove one or more abnormal parathyroid glands. The glands can be abnormal due to cancer or for other reasons.

A minimally invasive approach is usually done if only one gland needs to be removed. If more than one gland needs to be removed or if the doctor needs to do additional surgery in the neck, a conventional approach may used instead, which involves making larger incisions.
