全甲状腺切除术加中央区淋巴结清除术

近年来甲状腺癌的发病率逐年提高。甲状腺癌根治术是甲状腺分化型癌的标准治疗手段，是其序贯治疗过程中最为重要的一环。规范的甲状腺癌根治术包括至少一侧甲状腺叶的切除（原发灶切除）和中央区淋巴结清除（区域引流淋巴结清除）。甲状腺分化型癌大多预后良好，但甲状腺癌术后一旦复发，往往直接侵犯气管、食管、颈动脉等重要器官，再次手术时由于粘连紧密，解剖层次紊乱，病灶切除困难，喉返神经损伤及甲状旁腺功能低下的概率将明显增高，严重影响疗效。因此规范化的甲状腺癌根治术，对提高分化型甲状腺癌疗效有重要意义。

Total thyroidectomy and central compartment neck dissection

The incidence of differentiated thyroid cancer （DTC） has been increasing in recent years. As a standardized therapeutic strategy, radical resection is the most important part of the sequential therapy of DTC. Standardized radical operation of thyroid cancer includes total thyroidectomy or sub-total thyroidectomy and central neck lymph nodes dissection （local drainage lymph nodes dissection）. At least, unilatateral lobectomy and paratracheal dissection should be done. Most cases of DTC have good prognosis, but recurrent cases may have the tumor involving the trachea, esophagus, and common carotid. Unclear anatomic level usually causes tissue adherence, which makes complete removal of the recurrent lesion difficult. Since there is the increased possibility of incidental injury of recurrent laryngeal nerve （RLN） and parathyroid gland （PT, curative effect would be decreased. So it is important to standardize the radical operation of DTC.
