**5. Conclusion**

The prevention of postoperative hypoparathyroidism entails several issues, including the concept of meticulous operation, the ability of parathyroid gland identification, the technique of parathyroid gland autotransplantation, and the principle of "the preservation of at least one vascularized parathyroid gland" [10, 22]. This chapter shows that the concept of "a layer of TBP" during CND can greatly improve the success rate of IPTG preservation in situ, thereby efficiently decreasing the incidence of temporary postoperative hypoparathyroidism, along with ensuring the completeness of lymph node dissection.
