AbstractDuring the 27‐year period from 1957 to 1984, four hundred thirty patients underwent total thyroidectomies for malignant or benign disease of the thyroid gland at our institutions. Thyroid cancer was found in 83.4% of cases, and 47.2% of these had concomitant lymph node dissections. Transient recurrent laryngeal nerve injury occurred in 6.2% of the entire series. Permanent unilateral vocal cord paralysis occurred in 2.5% of the patients operated on, although only 1 patient (0.45%) sustained this complication in the past 14 years. No patient had permanent bilateral vocal cord paralysis. Transient hypoparathyroidism was seen in 16.8% of patients with permanent hypoparathyroidism occurring in 4.0%. The incidence of permanent hypoparathyroidism fell to 2.7% during the past 14 years and was directly related to the extent of thyroid cancer found at operation. Postoperative complications decrease with the experience of the surgeon and increase with reoperations and extensive disease. Total thyroidectomy continues to be our treatment of choice for thyroid cancer.
