Objective: To explore a new identification and protection method of the parathyroid gland in reoperation for thyroid diseases.
Method: 54 patients receiving reoperation for thyroid diseases were selected. The experiment group intraoperatively adopted carbon nanoparticles suspension for negative development of the parathyroid gland, whereas the control group did not use carbon nanoparticles suspension.
Results: At 48 h after surgery, the parathyroid hormone level was lower than the normal state in 9 patients (33.30%) of the control group and 1 patient (3.70%) of the experiment group; meanwhile, 6 months after surgery, 8 patients of the control group (29.63%) and 1 patient of the experiment group (3.70%) showed a lower level than the normal state with statistical differences. The serum calcium level in 10 patients of the control group (37.04%) and 2 patients of the experiment group (7.41%) was lower than the normal state at 48 h after surgery, while a lower level than the normal state was also shown in 8 patients of the control group (29.63%) and 1 patient of the experiment group (3.70%) 6 months after surgery with statistically significant between the two groups. A total of 10 (37.04%) and 1 parathyroid gland (3.70%) were detected with a statistical difference in both groups.
Conclusion: By adopting carbon nanoparticles in reoperation for the thyroid diseases and negative development of the parathyroid gland for identification and protection of the parathyroid gland, the incidence of hypoparathyroidism is reduced effectively, thus improving the postoperative quality of life of the patients.
