One of the postoperative complications after strumectomy is hypoparathyroidism.Therefore, the purpose of our study was to evaluate the effect of the surgical technique on the developmentof parathyroid gland insufficiency in our group of patients. Subtotal, bilateral strumectomies were performedaccording to Rothmund's suggestions. Randomized controlled trial was performed in two groups. In thefirst group of 19 patients, main trunk of the inferior thyroid artery was ligated and in the second oneconsisting of 18 patients, only the branches of this artery were ligated. Total calcium and PTH levelswere evaluated pre- and postoperatively. Based on the biochemical and clinical data, no statisticallysignificant differences in the development of postoperative hypoparathyroidism in relation to performedsurgical techniques were observed.
