Abstract: Objective The aim of this study was to investigate the distribution of metastatic lymph nodes and other common lymph node in the neck anatomy of high frequency ultrasound.Methods A retrospective analysis of 547 cases of neck lymph nodes from September 2016 to September 2017 was performed.According to the pathological results,it was divided into non-specific lymphadenitis,lymph node tuberculosis,lymphoma and metastatic lymph nodes.The routine ultrasound parameters of lymph nodes and its distribution in the anatomical section of the neck lymph nodes were recorded.Results The distribution of different neck lymph node diseases in the anatomical section of the neck lymph nodes was different.The neck lymph node metastasis of head and neck tumors was mostly distributed in Ⅱ(62.00%),Ⅲ(54.00%)and Ⅳ areas(53.00%).The neck lymph node metastasis of primary subclavian tumors was mainly distributed in Ⅴ(72.56%)and Ⅳ areas(34.15%).For specific tumors,there were also high risk area of lymph node metastasis.Conclusion Ultrasound can show the distribution of lymph nodes disease in the anatomical section of the neck.Preoperatively clear the distribution of lymph node disease in the anatomical zone can provide a more accurate basis for clinical diagnosis,surgical operation and cleaning range.
