Objective: To determine the most effective preoperative localization techniques for patients with primary hyperparathyroidism to facilitate the surgical procedure, decrease patient morbidity, and decrease the number of repeat surgeries owing to inability to locate the abnormal parathyroid gland.
Methods: This was a retrospective study in which 53 patients with primary hyperparathyroidism underwent preoperative sestamibi scanning and ultrasonography. If the two tests failed to agree on the precise location of the abnormal gland, a third imaging technique, magnetic resonance imaging (MRI), was used to confirm the precise location of the gland.
