目的 :探讨超声检查诊断口腔鳞状细胞癌颈淋巴结转移的方法。方法 :19名口腔鳞状细胞癌患者经二维超声检查 ,共发现肿大的颈淋巴结 34个 ,记录淋巴结的长短径之比 ,再对其中 16个淋巴结内有血流者 ,测量Vmax和Vmin值 ,并计算RI值。其后患者行根治性淋巴结清扫术 ,解剖出肿大淋巴结作病理检查 ,最后作各组间对比分析。结果 :①有癌转移的淋巴结组与无癌转移的淋巴结组间RI值具有显著性差异 ,而两组间淋巴结长短径之比和Vmax值均无显著性差异。②当以彩色多普勒检查得到的RI≥ 0 6 5和Vmax≥ 0 2 0m s作为阳性诊断指标时 ,敏感性为90 % (9 10 ) ,特异性为 91 7% (2 2 2 4) ,准确性为 91 2 % (31 34)。结论 :彩色多普勒超声是诊断口腔鳞状细胞癌颈淋巴结转移的有效方法。
Objective: To explore the method of ultrasonography in diagnosis of cervical lymph node metastasis of oral squamous cell carcinoma. Methods: Twenty-nine patients with oral squamous cell carcinoma underwent two-dimensional ultrasonography, 34 cases of enlarged cervical lymph nodes were found, the ratio of the length to the diameter of the lymph nodes was recorded, and the blood flow was detected in 16 of the lymph nodes. Vmax and Vmin Value and calculate the RI value. Subsequently, patients underwent radical lymphadenectomy, dissected swollen lymph nodes for pathological examination, and finally for the comparative analysis between the groups. Results: There was significant difference in RI between lymph node metastasis group and non-metastasis lymph node group, but there was no significant difference between the two groups. ② When RI ≥ 0 6 5 and Vmax ≥ 0 2 0m s obtained by color Doppler were positive diagnostic indexes, the sensitivity was 90% (9 10) and the specificity was 91 7% (2 2 2 4) , With an accuracy of 91 2% (31 34). Conclusion: Color Doppler ultrasound is an effective method to diagnose cervical lymph node metastasis in oral squamous cell carcinoma.
