Abstract
BACKGROUND: The purpose of this study was to evaluate preoperative features, surgical details, and postoperative findings related to the identification of parathyroid glands and to establish the relationship between identification of parathyroid glands and postoperative hypocalcemia. METHODS: Seven hundred eighty-eight total thyroidectomies performed between January 2002 and April 2012 by a single surgeon were studied. To evaluate the impact of parathyroid glands identification on study variables, patients were stratified into 2 study groups: group 1 with 0 to 2 parathyroid glands identified and group 2 with 3 to 4 parathyroid glands identified. RESULTS: Multivariate analysis identified younger age (p = .007), female sex (p = .001), and no usage of the Biclamp hemostatic technique (p < .001) related to the higher number of parathyroid glands identified. Univariate analysis revealed a higher incidence of temporary hypocalcemia (p = .015) and permanent hypoparathyroidism (p = .040) in group 2 than in group 1. CONCLUSION: Identification of a higher number of parathyroid glands is associated with a higher incidence of postoperative temporary hypocalcemia and permanent hypoparathyroidism.
