Aim: The aim was to introduce a new surgical method and to verify its validity. Methodology: In 20 patients whose ultrasound findings correlated with the MIBI scintigraphic results, a radiation-navigated parathyreoidectomy using a C-Track was conducted, following a radionucleotide application. Results: From 2001 to 2003, 20 patients with hyperparathyreosis were operated. In all cases, an altered parathyroid gland with increased activity was detected using radionavigation. After the surgery, the calcium and the parathormone blood levels decreased. Conclusion: The MIRP is a miniinvasive surgical method indicated for the use in cases when hyperparathyreosis is confirmed and the ultrasound findings correlate with the MIBI-scintigraphic findings.
