Task: Answer Verification
Input (English): Question: Are parathyroidectomy in primary hyperparathyroidism : preoperative localization and routine biopsy of unaltered glands necessary?
Answer: Our surgical strategy for treatment of primary hyperparathyroidism has proved to be safe with a favorable outcome in more than 95% of patients. This was possible without the routine use of preoperative localization studies and intraoperative biopsy of macroscopically normal glands. Routine biopsy of normal-appearing glands seems to be unnecessary and may increase the risk of hypoparathyroidism.
Output (English): no
