Value of intraoperative parathyroid hormone monitoring in papillary thyroid cancer surgery: can it be used to guide the choice of operation methods?

To assess the diagnostic value of decreased parathyroid hormone (PTH) in hypoparathyroidism after unilateral operation. A study was conducted on patients with PTC undergoing total or near-total thyroidectomy plus central neck dissection (CND). Postoperative hypocalcemia was found in 42 patients (51.2%). For patients undergoing bilateral CND, those whose tumor invasion proceeded beyond the thyroid capsule have a higher rate of postoperative hypoparathyroidism (P
