Parathyroid gland transplantation after total thyroidectomy with pharyngolaryngoesophagectomy

Surgical treatment of extensive hypopharyngeal carcinoma often includes total thyroidectomy together with resection of the primary disease. The risk of removing or damaging the parathyroid glands is considerable; this may render the patient permanently hypoparathyroid with all the problems of management. These patients must be on lifelong supplementation and at times, due to failure to take the medication, hypocalcemic crises are precipitated. To avoid this problem, we have been identifying the parathyroid glands intraoperatively and, after pathological confirmation, have transplanted them to the forearm. Three patients who underwent this procedure are presented. All are normocalcemic without supplementation and parathyroid hormone assays on serum from the transplanted forearm show significantly elevated levels.
