Endolaryngeal spread of laryngeal malignant tumours is usually determined by conventional endoscopy; however, it can not measure the outward extension of the tumour. As an alternative method for assessing the extension of a tumour and detecting metastatic lymph nodes, we have introduced high-resolution ultrasonography (US) in 34 patients with laryngeal epidermoid carcinoma. The ultrasonographic results were compared with the clinical, operative and histological findings. The ultrasonography revealed malignant extensions in the thyroid cartilage in nine cases, in the carotid artery in four cases, and in the thyroid gland in five cases. These were confirmed by surgical and histopathological examinations. Six patients out of the 34 were subclinical cases, who had metastatic lymph nodes, which were diagnosed by US only. In this study US had a sensitivity of 94.44 per cent and a specificity of 93.75 per cent. The sensitivity and specificity of palpation of the cervical lymph nodes were 66.66 per cent and 87.55 per cent respectively. It may be concluded that high-resolution real-time US is a sensitive, simple and inexpensive method for evaluating laryngeal cancers and subclinical cervical lymph node metastasis.
喉恶性肿瘤的喉内扩散通常通过传统内镜检查来确定；然而，它无法测量肿瘤的向外扩展情况。作为评估肿瘤扩展和检测转移性淋巴结的替代方法，我们对34例喉表皮样癌患者采用了高分辨率超声检查（US）。将超声检查结果与临床、手术及组织学检查结果进行了比较。超声检查发现9例甲状腺软骨有恶性扩展，4例颈动脉有恶性扩展，5例甲状腺有恶性扩展。这些均经手术及组织病理学检查证实。34例患者中有6例为亚临床病例，其有转移性淋巴结，仅通过超声检查得以诊断。在本研究中，超声检查的敏感性为94.44%，特异性为93.75%。颈部淋巴结触诊的敏感性和特异性分别为66.66%和87.55%。可以得出结论，高分辨率实时超声检查是一种评估喉癌及亚临床颈部淋巴结转移的敏感、简单且廉价的方法。
