Total thyroidectomy is an operation that has generally been reserved for the management of differentiated thyroid carcinoma. Over the last decade total thyroidectomy has become used increasingly and is now the preferred option in the authors' unit for the management of multinodular goiter affecting the entire gland. Over the period from 1975 to 1985, 853 thyroidectomies have been performed for multinodular goiter; of these, 115 have been total thyroidectomies. During that time, the incidence of total thyroidectomy for multinodular goiter has increased in percentage terms from 9% in 1975 to 50% in 1985. There have been two cases of permanent hypoparathyroidism and one case of permanent recurrent laryngeal nerve injury, and these occurred in patients who had less than total thyroidectomy. Total thyroidectomy is an appropriate operation for the management of diffuse multinodular goiter where the entire gland is involved because it precludes patients from requiring further surgery for recurrent disease, with its high associated risks. It must be emphasized, however, that protection of the recurrent laryngeal nerve and parathyroid glands must still be paramount in dealing with benign thyroid disease.
