parathyroid gland reimplantation
Surgical procedure involving transplantation of parathyroid tissue to prevent permanent hypoparathyroidism after inadvertent removal.
Full Definition
Parathyroid gland reimplantation is performed when parathyroid glands are inadvertently removed during thyroid or neck surgery, or when their blood supply is compromised. The procedure involves mincing the parathyroid tissue into 1-2mm fragments and implanting them into muscle pockets, typically in the sternocleidomastoid or forearm muscles. The reimplanted tissue can restore parathyroid hormone production and prevent permanent hypoparathyroidism. Success is monitored through serial calcium and parathyroid hormone levels, with function typically returning within 2-4 weeks.
Usage
Usage note: Often abbreviated as 'reimplantation' in surgical contexts.
