Clinical Characteristics for Early Recovery from Temporary Hypoparathyroidism in Patients Undergoing Total Thyroidectomy

Purpose: Several reports have examined the predictors of temporary hypoparathyroidism after total thyroidectomy; however, few have assessed the clinical predictors of early recovery from the condition. Here, we compared the clinical factors of early and late recovery groups of patients with temporary hypoparathyroidism.Methods: The electronic medical records of 248 patients who underwent total thyroi-dectomy from January 2012 to July 2013 and had parathyroid hormone (PTH) levels ＜10 pg/mL on the first postoperative day were examined retrospectively. The early recovery group showed recovery from PTH at two weeks postoperatively and the late recovery group showed recovery from PTH at one month postoperatively.Results: The early recovery group included a lower proportion of males (8.6% vs. 23.7%, P＜0.01) and a higher proportion of patients with more than three parathyroid glands saved (83.8% vs. 76.8%, P＜0.04). There were no significant differences in the other variables examined.Conclusion: The early recovery group of patients with temporary hypoparathyroidism included a lower proportion of males and a higher proportion of patients with more than three parathyroid glands saved intraoperatively. These findings can be used as clinical indicators when discharge medication is prescribed.
