We compared the preoperative ultrasound findings with the histological results of 127 neck dissections for squamous cell carcinoma of the head and neck. We checked several sonomorphological criteria (size, shape, boundary, echo structure, arrangement, mobility) to assess their value in identification of metastatic disease. If all nodes found on ultrasound were classed as metastases, the specificity was 30%, because many lymph nodes showed nonspecific reaction only. Lymph nodes with a rupture of the capsule or central necrosis or being larger than 3 cm, proved to be metastatic in all cases. Round or oval nodes with a size of more than 2 cm were found to be metastatic with an accuracy of 89%. The almost certain (97%) identification of necks with no metastatic lymph nodes allows elective neck dissection to be avoided.
我们将127例头颈部鳞状细胞癌颈部清扫术的术前超声检查结果与组织学结果进行了比较。我们检查了几个超声形态学标准（大小、形状、边界、回声结构、排列、活动度），以评估它们在识别转移性疾病中的价值。如果超声发现的所有淋巴结都被归类为转移灶，特异性为30%，因为许多淋巴结仅表现出非特异性反应。包膜破裂、中央坏死或直径大于3 cm的淋巴结在所有病例中均被证实为转移灶。直径大于2 cm的圆形或椭圆形淋巴结被发现为转移灶的准确率为89%。几乎可以肯定（97%）识别出无转移性淋巴结的颈部，从而避免选择性颈部清扫术。
