Sixteen of them presented with hyperparathyroidism. The patients received ultrasounography, CT or 99mTc-MIBI to locate the tumor site. Serum concentrations of PTH and calcium were checked before the operation. All operations were performed under general anesthesia. The adenomas were resected and the four glands explored.Results All of the patients were cured and there was no mortality in our group. The symptoms of hyperparathyroidism remitted to various degrees after the operation. PTH dropped to the normal range 2 days after operation. Serum calcium concentrations declined to different levels from the first day after operation. Seven patients developed hypocalcemia post-operation but recovered by injection of calcium gluconate. Only one of the patients with parathyroid adenoma recurred 2 years after the operation and was found to have malignancy of the parathyroid adenoma.CONCLUSION Not all the patients with parathyroid adenoma had clinical manifestations. The CT and 99mTc-MIBI were more accurate than ultrasounography in locating the adenoma. The four glands should be explored during the operation. Protecting the recurrent laryngeal nerve from being injuried and maintaning secure hemastasis were most important.
