[Ultrasonography of cervical lymphatic metastasis in patients with laryngeal neoplasms].
112 patients with larynx cancer underwent ultrasonography of neck lymph nodes to asses their metastatic involvement before surgical treatment. Evaluation of the nodes was also performed by means of simple palpation. Results of palpation and ultrasonographic examination were compared in terms of efficacy in detecting and recognition of metastatic spread within lymphatic system of neck. The final assessment was based on results of intraoperative exploration and histological examination. Results indicate that ultrasonographic evaluation is more efficient in recognition of metastases to nodes of neck then physical examination based on palpation. The authors concluded that ultrasonography as a simple and available method can be effective in detection of metastases of ca larynx to lymphatic system of neck.
