Question

Quizplus · Accepted Answer

Patients who do not respond well to antithyroid drug therapy,who are unable to take radioactive iodine,or who have greatly enlarged thyroid glands are candidates for a subtotal thyroidectomy.In the subtotal procedure,two thirds of the glandular mass is removed.The remaining portion of the gland is left intact so production and release of thyroid hormone can continue.There is no need for antithyroid drugs,and the operative risks are the same.
