Answer

Surgical treatment should be offered to most patients with primary hyperparathyroidism. The historical criterion-standard operative approach is complete neck exploration with identification of all parathyroid glands and removal of all abnormal glands. Approximately 85% of cases of primary hyperparathyroidism are caused by a single adenoma. Therefore, most patients who undergo full neck exploration to evaluate all parathyroids endure some unnecessary dissection. Rather than explore all parathyroid glands, a newer technique, directed parathyroidectomy, has evolved. This technique relies on preoperative imaging studies to localize the abnormal gland. The surgeon then removes only that gland, without visualizing the other glands.
