摘　　要：目的　探讨超声在喉癌和下咽癌颈部淋巴结转移诊断中的价值。方法　应用超声检查37 例喉癌和下咽癌患者的颈部淋巴结,所见与手术病理结果对照分析。结果　超声检查发现并与手术切除对照符合的淋巴结总数177 个,超声诊断淋巴结转移的敏感度为91.3% (94/103),特异度85.1% (63/74),假阳性率14.9%,假阴性率8.7%。多因素Logistic回归分析结果显示,淋巴结内部回声不均匀、无髓质或髓质位置偏心、淋巴结血流信号杂乱预示淋巴结有转移。淋巴结回声均匀、髓质居中、血流规则预示无转移。结论　喉癌和下咽癌患者术前进行超声检查有助于淋巴结转移与否的诊断。Objective To investigate the value of ultrasound in diagnosis of metastatic lymph nodes of larynx and hypopharynx cancer. Methods Neck nodes of 37 patients with laryngeal and hypopharyngeal cancer were observed, the results were compared with surgery and with pathological findings. Results A total of 177 lymph nodes in 37 cases were analyzed. The sensitivity and specificity of ultrasound in evaluating metastasis were 91.3% and 85.1%, respectively, while false positive rate and false negative rate were 14.9% and 8.7%, respectively. Multivariate logistic regression analysis revealed that lymph nodes with non-homogenous internal echo, eccentric medulla or without medulla and CDE irregular vascular type suggest metastasis positive while lymph nodes with homogenous echo, central medulla, CDE with regular central type suggest metastasis negative. Conclusion Ultrasonography is valuable in detecting metastatic lymph nodes in patients with larynx and hypopharynx cancer.
