A study was conducted on the value of Ultrasound (US) in the detection of cervical lymph node metastases in cases of Head and Neck malignancy; and its usefulness in planning surgical management. The clinical, ullrasonographic and histopathological examination (HPE) findings were compared in 20 patients as a preliminary assessment of this ongoing study. Clinically and ultrasonogiaphically, patients were assessed for presence of nodes, their size, shape, mobility and overall positivity for malignancy. All patients then underwent neck dissection, and individual nodes from the specimens were assessed by HPE.It was found that US, when compared with clinical examination had a sensitivity of 47.62% versus 43.75%, specificity of 77.78% versus 25.0% and an accuracy of 61.54% as opposed to 38.9%. US proved valuable in detecting sub-clinical nodes, central necrosis, extra-capsular spread, pressure on large vessels - all indicators of metastatic spread. Hence, US was found to be efficient and cost-effective pre-operatively, in planning surgical management.
一项关于超声（US）在头颈部恶性肿瘤病例中检测颈部淋巴结转移的价值及其在规划手术治疗中的作用的研究。作为这项正在进行的研究的初步评估，对20例患者的临床、超声检查和组织病理学检查（HPE）结果进行了比较。在临床和超声检查中，评估患者是否存在淋巴结、其大小、形状、活动度以及恶性肿瘤的总体阳性情况。然后所有患者均接受颈部清扫术，并通过HPE对标本中的单个淋巴结进行评估。结果发现，与临床检查相比，超声的敏感性为47.62%，而临床检查为43.75%；特异性为77.78%，而临床检查为25.0%；准确性为61.54%，而临床检查为38.9%。超声在检测亚临床淋巴结、中央坏死、包膜外扩散、对大血管的压迫方面被证明具有价值，这些都是转移扩散的指标。因此，超声在术前规划手术治疗方面被发现是有效且具有成本效益的。
