甲状腺乳头状癌右侧喉返神经深层淋巴结转移及清扫

Metastasis and dissection of lymph node posterior to right recurrent laryngeal nerve of papillary thyroid carcinoma

淋巴结转移是甲状腺乳头状癌转移的主要方式。在中央区淋巴结清扫中，右侧喉返神经深层淋巴结因解剖位置深而十分隐蔽，在手术过程中容易被遗漏，而成为甲状腺乳头状癌复发的影响因素之一。右侧喉返神经深层淋巴结转移率为10％～30％，与肿瘤大小、位置等诸多因素相关，在甲状腺癌外科治疗中的地位日益凸显。

Lymph node metastasis is the main mode of metastasis of thyroid papillary carcinoma. In the central compartment lymph node dissection, the lymph node posterior to right recurrent laryngeal nerve is hidden because of its deep anatomical position, which is easy to be missed during the operation and becomes one of the factors that affect the recurrence of thyroid papillary carcinoma. The metastasis rate of lymph node posterior to right recurrent laryngeal nerve is 10%-30% , which is related to the tumor size, location and other factors, and its position in the surgical treatment of thyroid cancer is increasingly prominent.
