The traditional surgical approach for primary hyperparathyroidism (PHPT) involves a bilateral neck exploration to identify all parathyroid glands and remove the suspected pathological parathyroid gland(s). However, with improved preoperative imaging modalities and the use of perioperative measuring of PTH the unilateral minimal invasive approach has been introduced. The purpose of this study was to describe the results of minimal invasive parathyroidectomy.
