目的：探讨超声检查诊断颈淋巴结转移的准确性及对颈部隐匿性淋巴结转移的诊断价值。方法：应用双盲法对５５ 例（６１ 侧）行颈廓清术患者的术前触诊、超声检查及术后病理检查进行对比分析。结果：６１ 侧中，病理证实 ５２ 侧有淋巴结转移，触诊和超声检出分别为 ４０ 侧和 ４８ 侧，其敏感性、特异性及准确性分别为７６．９％ 和９２．３％ （ Ｐ ＜ ０．０５）、７７．８％ 和８８．９％ （ Ｐ ＞ ０．０５）及７７．０％ 和９１．８％ （ Ｐ ＜ ０．０５）。１２ 侧触诊假阴性（隐匿性转移）超声检出阳性６ 侧。结论：超声检查颈淋巴结转移的准确性优于触诊，并可检出约半数隐匿性转移淋巴结，超声可作为诊断颈淋巴结转移的常规检查项目。
Objective: To investigate the accuracy of ultrasound in the diagnosis of cervical lymph node metastasis and the diagnostic value of occult lymph node metastasis in the neck. METHODS: The preoperative palpation, ultrasonography and postoperative pathological examination of 55 patients (61 sides) undergoing neck dissection were compared using a double-blind method. RESULTS: On the 61 sides, pathologically confirmed lymph node metastasis on 52 sides, palpation and sonographic examinations were 40 and 48, respectively, with sensitivity, specificity, and accuracy of 76.9% and 92.3%, respectively (P <0.05), 77.8% and 88.9% (P>0.05), and 77.0% and 91.8% (P < 0.05). 12 side false negatives (occult metastases) were detected by ultrasound on the positive side. Conclusion: The accuracy of ultrasound in the detection of cervical lymph node metastasis is better than that of palpation, and approximately half of occult lymph nodes can be detected. Ultrasound can be used as a routine examination item for the diagnosis of cervical lymph node metastasis.
