Objective To investigate the risk factors for hypoparathyroidism following radical surgery for patients with thyroid papillary carcinoma (PTC).Methods A retrospective analysis was made on 192 patients with PTC who underwent radical thyroidectomy in the Department of Head Neck and Thyroid Surgery of Henan Cancer Hospital from January 2019 to January 2020. There were 52 males and 140 females with a median age of 48 years. The risk factors of hypocalcemia and hypoparathyroidism syndrome were screened by χ2 test and binary logistic regression analysis.Results In 192 patients the proportion of patients with normal or hypoparathyroidism after operation were 62.5% (120/192) and 37.5% (72/192), respectively. Univariate analysis showed that complications, Hashimoto’s thyroiditis (HT), total thyroidectomy, N1a staging, Ⅵ lymph node dissection and parathyroid not planted were risk factors for postoperative hypoparathyroidism in patients with PTC. Binary logistic regression analysis showed that: ① HT, N1a staging and Ⅵ lymph node dissection were independent risk factors for postoperative hypocalcemia [without HT: OR=0.313, 95%CI (0.129, 0.760), P=0.010; N1a staging: OR=3.457, 95%CI (1.637, 7.301), P=0.001; without Ⅵ lymph node dissection: OR=0.115, 95%CI (0.041, 0.323), P<0.001]. ② HT, N1a staging, Ⅵ lymph node dissection and parathyroid not planted were independent risk factors for postoperative low parathyroid hormone [without HT: OR=0.285, 95%CI (0.117, 0.698), P=0.006; N1a staging: OR=3.747, 95%CI (1.762, 7.968), P=0.001; without Ⅵ lymph node dissection: OR=0.112, 95%CI (0.039, 0.317), P<0.010; planted parathyroid: OR=0.464, 95%CI (0.221, 0.978), P=0.043].Conclusion HT, N1a staging, Ⅵ lymph node dissection and parathyroid not planted are vital risk factors for hypoparathyroidism in patients with PTC after radical thyroidectomy.
