Abstract

|
The preservation of the parathyroid gland during thyroid surgery is still challenging; Intraoperative detection of parathyroid glands using near-infrared autofluorescence (NIRAF) has been recently introduced as a solution. NIRAF is noninvasive and it can be applied without contrast dye. Recently, increasing number of studies using NIRAF to detect parathyroid glands under normal or hyperparathyroidism state have been reported, and commercialized products of the imaging devices or probe systems have been produced. NIRAF imaging is also useful to find unrevealed parathyroid gland tissues before exposure, and early localization reduces unintended removal or blood vessel damage of parathyroid glands. It has been reported that this technique significantly decreases the incidence of early postoperative hypocalcemia.
