453 patients underwent surgery for primary hyperparathyreoidism between 1994 and 2003. In all patients, biochemical parameters were monitored and X-ray with USG of the neck was done. Struma nodosa was concommitantly present in 48 % of treated patients with primary hyperparathyroidism. In such cases, MRI offers better resolution of soft tissues. 98.6 % of treated patients had postoperative decrease of blood calcium to normal level. 5.4 % of cases were reoperations for primary hyperparathyroidism. In 12 % of cases, pathologically changed parathyroid glands in dystopic localization were found. In these dystopic localizations, pathologic parathyroid glands were found: in 3 % intrathyroid, in 7 % mediastinal and in 2 % of all 453 cases in other localization. In 4 % of patients, sternotomy was necessary. Persistent hypocalcemia was not registered in any patient. Transient hypocalcemia with necessity of infusion therapy was observed in 3.5 % of patients. Postoperative hypercalcemia persisted in 1.2 % of patients. Recurrent hypercalcemia was present in 0.2 % of cases. In three cases (0.7 %), unilateral injury of recurrent laryngeal nerve was observed.
