Abstract
Evaluation of cases operated with hyperparathyroidism. 24 cases of hyperparathyroidism were reported. Priamry 16 cases and secondary 8 cases were discussed with reference to the procedures of preoperative diagnosis and operation. During the surgery, all of the four parathyroid glands must be searched since more than two glands may occasionally be accompanied with hyper function. Results were succeeded in all cases except a case.
