RECURRENT HYPERPARATHYROIDISM

RECURRENT HYPERPARATHYROIDISM

Recurrent hyperparathyroidism is defined as hypercalcaemia occurring 6 months after surgery but with an intervening period of normocalcaemia. Common causes include missed pathology at the first operation; hyperplasia in remaining or autotransplanted tissue; parathyromatosis; or, very rarely , the development of a second parathyroid adenoma. Parathyro matosis refers to disseminated parathyroid tissue within the rupture of the parathyroid gland during the primary surgery . A definitive indication for surgical intervention must be present prior to embarking on localisa tion studies. Surgical interven - tion will be guided by the radiological imaging. Complication rates of recurrent laryngeal nerve damage and permanent hypocalcaemia are higher in reoperative surgery . RECURRENT HYPERPARATHYROIDISM
