A rapid morphometric method for determining thyroid gland function

The incidence of postoperative hypothyrosis after subtotal resection of the thyroid for diffuse toxic goiter is rather high, 40-50% according to many authors. A method is suggested permitting assessment of the share of "active zones" during surgery. A certain amount of thyroid tissue is left with due consideration for this share, this amount being sufficient to attain an euthyroid state in the postoperative period.
