Abstract:
To investigate the risk factors for hypoparathyroidism after thyroidectomy.
Methods: Clinical data of 492 patients, who underwent thyroidectomy from April 2015 to December 2016 from Xiangya Hospital of Central South University, were studied retrospectively. Chi-square test and multivariable logistic regression were performed to find the risk factors for postoperative hypoparathyroidism.
Results: The incidence of postoperative hypoparathyroidism was 43.5%, and the incidence of temporary and permanent hypoparathyroidism was 43.1% and 0.4%, respectively. Univariate analysis showed that tumor pathology, thyroidectomy types, the extent of lymph node dissection, application of carbon nanoparticles, and merged Hashimoto's thyroiditis were risk factors for postoperative hypoparathyroidism (all P<0.01). Logistic regression analysis showed that: thyroidectomy types (OR=0.149, 95% CI 0.078 to 0.28), the extent lymph node dissection (OR=0.779, 95% CI 0.617 to 0.983) and application of carbon nanoparticles (OR=1.729,
95% CI 1.067 to 2.801) were independent risk factors for postoperative hypoparathyroidism (all P<0.05).
Conclusion: Hypoparathyroidism is a common complication after thyroidectomy. The incidence of postoperative hypoparathyroidism is significantly increased in patients underwent total thyroidectomy and cervical lymph node dissection. Application of carbon nanoparticles intraoperatively can reduce the incidence of postoperative hypoparathyroidism.
