甲状腺癌易发生淋巴转移,因此甲状腺切除+中央区淋巴结清扫术是甲状腺癌的主要手术方式,但至今尚无一种标准的操作方法。我们通过对颈筋膜的解剖学研究和临床手术观察后发现,同结直肠相似,甲状腺周围也存在脏壁二层筋膜,甲状腺及其周围脂肪淋巴组织被脏层筋膜包绕,与周围壁层筋膜之间存在一个潜在的筋膜间隙;而中央区脂肪淋巴组织被前后两层筋膜覆盖,血管、淋巴管走行其中,结构类似肠系膜。循脏壁二层筋膜之间的间隙进行手术,将系膜样结构 Thyroid cancer is prone to lymphatic metastasis, so thyroidectomy + central lymph node dissection is the main surgical method for thyroid cancer, but so far there is no standard method of operation. Through anatomical studies of the cervical fascia and clinical observations, we found that similar to the colorectal tissue, there is also a visceral two-layer fascia around the thyroid. The thyroid gland and its surrounding fat lymphoid tissue are surrounded by the visceral fascia and are surrounded by it. There is a latent fascial space between the parietal fascia; the fat lymphoid tissue in the central area is covered by two anterior and posterior fascias, and the blood vessels and lymphatic vessels go through and the structure resembles the mesentery. Operates through the gap between the two layers of the visceral fascia and the mesangial structure
