Aim. We aimed to determine the prevalence and and risk factors for postoperative hypocalcemia in patients who underwent thyroidectomy. Methods. A total of 271 patients (mean age, 46.21±12.50 years; female/male ratio, 229/42) who underwent thyroidectomy were divided retrospectively into two groups according to whether or not they developed hypocalcemia after thyroidectomy. Results. Of the 271 patients, 74 (27.3%) have developed hypocalcemia after thyroidectomy. The fine-needle aspiration biopsy, preoperative thyroiditis, malignancy, and accompanying neck dissection surgery were more common among patients with postoperative hypocalcemia (P<0.05 for all). In multivariate analysis, thyroiditis was not a significant predictor for postoperative hypocalcemia (P=0.228). The weight of the excised thyroid gland was significantly higher in patients with postoperative hypocalcemia (P=0.005). Conclusion. In conclusion, the patients undergoing thyroidectomy have a high risk of developing postoperative hypocalcemia. The fine-needle aspiration biopsy, malignancy, neck dissection surgery and increased weight of the excised thyroid gland are risk factors for hypocalcemia after thyroidectomy.
