These 9 patients had 14 prior explorations for HPT including 4\u00a0median sternotomies and 5 thyroidectomies<\/jats:bold>.<\/jats:p><jats:p>Each of the 9 patients was symptomatic of HPT, including bone disease in 8 of 9 patients and renal stones in 4 of 9 patients. Seven patients had an undescended parathyroid adenoma correctly localized preoperatively by ultrasound (n=5), angiography (n=5), venous sampling (n=1), or computed tomography scan (n=4). These 7 patients with accurate preoperative localization were explored by an incision anterior to the sternocleidomastoid muscle high in the neck that avoided the previous operative field and allowed rapid resection of the parathyroid adenoma. In the 2 patients who did not have accurate preoperative localization, the undescended adenoma was found after long tedious exploration including median sternotomy in 1 patient. Each patient (n=9) who had an undescended parathyroid adenoma removed was cured of hypercalcemia, and 5 patients required postoperative 1,25\u2010dihydroxy vitamin D<jats:sub>3<\/jats:sub> for hypocalcemia.<\/jats:p><jats:p><jats:bold>We conclude that undescended parathyroid adenomas comprise a significant proportion (9%) of adenomas during reoperations for persistent HPT.
