随着甲状腺癌的发病率上升，全甲状腺切除率也随之上升，甲状旁腺损伤产生的低钙血症是甲状腺癌根治术的一个重要并发症之一。由于甲状旁腺与甲状腺关系密切，血供脆弱及解剖变异大，所以，在行甲状腺癌根治术时要仔细辨认与保护甲状旁腺，上甲状旁腺应强调原位保护，而下甲状旁腺应以原位保护与自体移植相结合。在彻底清除病灶基础上，尽可能保护每一枚甲状旁腺。

Parathyroid reservation in the surgery of thyroid carcinoma        WU Yi. Department of Head and Neck Surgery, Fudan University Shanghai Cancer Center (FUSCC),Shanghai 200032, China
Abstract    Since the incidence of thyroid carcinoma has been elevated, the number of patients received the radical surgery of bilateral thyroid carcinoma has also increased. Hypoparathyroidism is a major complication after total thyroidectomy due to the anatomy and vascularation. The superior parathyroid should be reserved in situ, as for the inferior parathyroid, in situ vascularized prarathyroid reservation combined with parathyroid autotransplantation should be applied. Effort should be made to ensure the reservation of each parathyroid as long as the radical dissection of original tumor has been done.
