What action should be taken if only 3 parathyroids are found and PTH drops appropriately?

In the scenario where three parathyroid glands have been identified and the parathyroid hormone (PTH) levels drop appropriately after their removal, the next logical step is to consider the missing gland. The primary role of the parathyroid glands is to regulate calcium levels in the body through the secretion of PTH. If three glands are functional and PTH levels drop, it suggests that the remaining glands are compensating adequately for the loss of the fourth gland.

Re-implanting the missing gland is important to restore parathyroid function fully. Studies indicate that if the missing parathyroid gland can be identified and re-implanted, this can help prevent complications such as postoperative hypoparathyroidism, which can lead to serious metabolic issues, including hypocalcemia. Ensuring that all functional parathyroid tissue is preserved in the patient can help to stabilize calcium levels more effectively in the long term.

In contrast, simply monitoring PTH levels might overlook the need for a functional fourth gland, which could leave the patient at risk for imbalances in calcium homeostasis. Performing a complete thyroidectomy is unnecessary since three parathyroid glands are already identified, and taking out healthy tissue could lead to further complications.
