Long-term follow-up of patients with Grave's disease treated by subtotal thyroidectomy

This long-term follow-up study of 83 patients with Grave's disease who were treated by subtotal thyroidectomy reemphasizes the fact that postoperative hypothyroidism occurs primarily in the first postoperative year (27 percent of the study patients). In addition, there was no evidence of progressive increase in the incidence of hypothyroidism in subsequent years. Patients treated with radioactive iodine have a reported incidence of hypothyroidism of 70 percent 10 years postoperatively [4]. The 6 percent incidence of recurrent hyperthyroidism is much less than a reported incidence of 90 percent in patients treated with long-term antithyroid drugs [7]. Subtotal thyroidectomy continues to be an excellent method of treatment for patients with Grave's disease and compared favorably with both radioactive iodine and long-term antithyroid drugs.
