Researchers are studying the effects of parathyroid autotransplantation in total parathyroidectomy for secondary hyperparathyroidism. The outcomes of different surgical approaches, including subtotal parathyroidectomy and selective parathyroid autotransplantation, are being examined to prevent complications such as permanent hypoparathyroidism. Various techniques, including near-infrared autofluorescence and intraoperative parathyroid hormone measurement, are being investigated to improve parathyroid gland identification and preservation during surgery.
