[OBJECTIVE] Persistent hypocalcemia caused by long-term hypoparathyroidism can significantly reduce the living quality of patients. The purpose of this study was to investigate possible factors affecting postoperative hypoparathyroidism. [METHODS] This study retrospective collected thyroid surgery cases from January 2015 to December 2017 in Luwan Branch of Ruijin Hospital Affiliated to Medical College of Shanghai Jiao Tong University. Moreover, we analyzed demographic data, operative data and perioperative examination indexes. Using logistic regression analysis to investigate possible factors affecting postoperative transient/long-term hypoparathyroidism. [RESULTS] Totally, 1381 people were collected, 343 male (24.84%) and 1038 female (75.16%), the average age was 47.9±13.0 years. Postoperative transient hypoparathyroidism occurred in 456 people (33.02%), and long-term hypoparathyroidism in 21 people (1.52%). After multivariate analysis, the main risk factors associated with postoperative transient hypoparathyroidism were gender(P<0.001, OR 0.486), maximum diameter of thyroid resection(P 0.011, OR 1.192), thyroid resection extent (P<0.001, OR 2.974), lymph node dissection(P 0.008, OR 1.569), surgery duration(P 0.034, OR 1.005), preoperative serum calcium(P<0.001, OR 0.028). The main risk factors associated with postoperative long-term hypoparathyroidism were thyroid resection extent (P<0.003, OR 5.443), surgery duration (P 0.021, OR 0.976), postoperative d1PTH (P<0.001, OR 1.199). [CONCLUSIONS] The risk factors for postoperative transient hypoparathyroidism include gender, the extent of thyroid resection, lymph node dissection, duration of surgery and preoperative serum calcium. The extent of resection and duration of surgery were risk factors for postoperative long-term hypoparathyroidism, and PTH on the early morning after surgery(d1PTH) was lower than normal, which had a predictive effect on long-term hypoparathyroidism.
