Application of carbon nanoparticles accelerates the rapid recovery of parathyroid function during thyroid carcinoma surgery with central lymph node dissection: A retrospective cohort study.

•In this study, carbon nanoparticles was associated with more central lymph nodes dissected and less parathyroid glands removed incidentally.•The follow-up outcomes showed that Carbon nanoparticles had played a key role in promoting rapid recovery of parathyroid function during thyroid carcinoma surgery with central lymph node dissection.•It was suggested to routinely use carbon nanoparticles during thyroid carcinoma surgery combined with central lymph node dissection.
