Abstract
PURPOSE: Hypocalcemia after total thyroidectomy is a concern for every endocrine surgeon. We conducted this study to establish the value of the macroscopic appearance of preserved parathyroid glands after thyroidectomy in predicting post-thyroidectomy hypocalcemia. METHODS: In 2009, 237 patients underwent total thyroidectomy at our hospital. The macroscopic appearance of the preserved parathyroid glands was recorded and the serum calcium and intact parathyroid hormone levels were measured postoperatively. RESULTS: Thirteen patients (5.5 %) had transient hypocalcemia and 1 patient (0.4 %) had permanent hypocalcemia. All of the hypocalcemia patients with more than one normal preserved parathyroid had asymptomatic transient hypocalcemia that did not require medication. The sensitivity, specificity, positive predictive value, and negative predictive value for hypocalcemia with at least 1 normal preserved parathyroid were 78.6, 79.4, 19.3, and 98.3 %, respectively. CONCLUSION: The macroscopic appearance of preserved parathyroid glands and the number of well-preserved parathyroid glands after thyroidectomy proved effective in predicting post-thyroidectomy hypocalcemia.
