OBJECTIVE
To research the accuracy of ultrasonography in the diagnosis of cervical lymph node metastasis and the value of that of cervical lymph node occult metastasis.
METHOD
Fifty-five patients(61 sides) operated by neck dissection were double-blindedly studied by preoperation palpation and ultrasonography comparing with postoperating pathological examination.
RESULT
Fifty-two sides were confirmed to be pathology lymph node metastasis from 61 sides. 40 and 48 sides were checked out by palpation and ultrasonography, respectively. The sensitivity, specificity and accuracy of palpation and ultrasonography were 76.9% and 92.3% (P < 0.05), 77.8% and 88.9%(P > 0.05) and 77.0% and 91.8%(P < 0.05), respectively. Six sides were checked out by ultrasonography (occult metastasis) in 12 sides of palpation negative.
CONCLUSION
The accuracy of ultrasonography was prior to that of palpation in examining cervical lymph node metastsis. Ultrasonography could check out about half occult metastasis and should be regarded as a routine examining items in diagnosing cervical lymph node metastasis.
目的
探讨超声检查在诊断颈部淋巴结转移中的准确性及对颈部隐匿性淋巴结转移的诊断价值。
方法
对55例（61侧）行颈清扫术的患者，术前分别采用触诊和超声检查，并与术后病理检查进行双盲对照研究。
结果
61侧中病理证实为淋巴结转移52侧。触诊检出40侧，超声检出48侧。触诊和超声检查的敏感度、特异度及准确度分别为76.9%和92.3%（P<0.05）、77.8%和88.9%（P>0.05）、77.0%和91.8%（P<0.05）。触诊阴性的12侧中，超声检出隐匿性转移6侧。
结论
超声检查诊断颈部淋巴结转移的准确度优于触诊。超声检查可检出约半数的隐匿性转移，应作为诊断颈部淋巴结转移的常规检查项目。
