Total thyroidectomy. A review of 213 patients.

During a 10.5-year period ending in June 1982, total thyroidectomy was performed on 213 patients at the Vanderbilt University Medical Center. A nonfunctioning nodule on technetium scan was the primary indication for operation. Twenty-one of 213 patients had undergone previous partial thyroidectomy. The pathologic changes in the excised thyroids were carcinoma (81 patients), thyroiditis (27 patients), multiple benign adenoma (16 patients), thyrotoxicosis (27 patients), multinodular goiter (56 patients), and C-cell hyperplasia (three patients). Three total thyroidectomies were performed in search of a parathyroid adenoma. Fourteen patients had coexistent primary hyperparathyroidism. Excluding 12 patients with medullary carcinoma, 25% of all other patients with carcinoma would have had unrecognized tumor left in the remaining lobe had a total thyroidectomy not been performed. Calcium supplements were required in 59 patients during hospitalization, but only 2.8% of the patients developed permanent hypoparathyroidism. Since the adoption of Thompson's technique of total thyroidectomy, only one of the 128 patients (0.8%) has sustained permanent hypoparathyroidism. Two patients exhibited transient recurrent laryngeal nerve palsies without permanent nerve damage. There were no operative deaths. The low morbidity of total thyroidectomy appears to justify its use in all patients with differentiated thyroid malignancy. With surgeons experienced in this technique, total thyroidectomy should also be considered as the primary treatment for many other patients requiring thyroidectomy.
