What is the surgery cure rate of parathyroid operation?

High. Assuming one parathyroid adenoma in the setting of primary hyperparathyroidism (one gland disease), the surgical cure rate can be as high as 95%. One gland disease is usually found in younger patients so younger patients will typically have a higher surgical success than older patients.
Nearly 100% With radioguidance and intraoperative PTH monitoring the cure rates for parathyroidectomy are close to 100%, provided the surgery is for primary hyperthyroidism. In cases of secondary or tertiary hyperparathyroidism, 4 gland excision with reimplant in forearm is performed in case there is recurrent hyperparathyroidism. Pieces of remaining parathyroid tissue can then be removed from forearm.
Cure rate. For an occasional operator, it should be above 80%. For a high volume surgeon, it would be greater than 95%.
