Modern Approach to Surgical Intervention of the Thyroid and Parathyroid Glands

Operative intervention on the parathyroid and thyroid glands has become more minimally invasive and selective over the past decade. This requires high-quality preoperative imaging evaluation for better knowledge of the relevant anatomical considerations and potential localization. Minimally invasive parathyroidectomy has become the operation of choice for most patients presenting with sporadic primary hyperparathyroidism (when the suspected parathyroid tumor is localized preoperatively). Preoperative imaging helps guide the surgeon as to which patients with thyroid pathology require intervention and the extent of resection. The imaging modalities reviewed include ultrasonography, technetium-99m sestamibi imaging, and four-dimensional computed tomography. Imaging modalities are discussed within the categories of benign and neoplastic parathyroid and thyroid pathology.
