Accurate identification of abnormal parathyroid glands (PGs) during parathyroidectomy and thyroidectomy can be challenging even for experienced surgeons given PGs variable location, size, and similar appearance to surrounding tissue. Inadvertent removal or devascularization of healthy PGs can lead to transient or permanent hypoparathyroidism. Permanent hypoparathyroidism is associated with increased rates of renal insufficiency, seizures, skeletal abnormalities, increased costs, decreased quality of life, and increased mortality. Conversely, the inability to identify and remove hyperfunctioning PGs results in failed parathyroidectomy which can result in need for reoperations that are associated with increased technical difficulty, operative duration, rates of hypoparathyroidism and recurrent laryngeal nerve damage, and cost.
