[Determination of PTH I in hyperparathyroidism surgery. Our experience].

Our Service of Otolaryngology has performed 90 parathyroidectomies at all since april 1990 to 2000 on 92 patients sent to us with diagnosis of hyperparathyroidism. 67 patients were diagnosed as primary hyperparathyroidism; 22 as secondary and 3 cases corresponded to tertiary hyperparathyroidism. We analysed a string of variables before and after the surgery standing out the recent estimate of rapid PTH i levels. The kind of surgery we performed was the removal of adenoma in 63 cases; 23 patients were put to subtotal parathyroidectomy and 4 to a total one. An exploratory neck surgery was performed in two patients without finding a parathyroid pathology. We compare the obtained results with other published series and we think it can be useful to determinate the rapid paratohormone levels (PTH i) pre and postsurgery (only used in 3 cases by now) in order to predict the clinic response of the patients with hyperparathyroidism.
