During sonographic (US) studies of the neck for the nodal staging of patients with laryngeal neoplasms, the authors observed that, especially in advanced cases, also the primary lesion could be imaged with this method. Therefore, US capabilities were investigated in assessing the local stage of laryngeal neoplasms; the results were compared with clinical and surgical findings. Fifty normal subjects of various ages were previously examined to assess the normal US anatomy of laryngeal structures. The presence of calcifications within the thyroid cartilage is the major obstacle to US imaging of the larynx and is directly related to age; indeed, only 40% of subjects can be examined at the age of 70. Seventeen patients with advanced laryngeal tumors were examined by US. Laryngeal imaging was possible, either in part or completely, in 16 of 17 cases. The results were in agreement with clinical staging in 14 cases; in 2 cases US proved clinical understaging by detecting lesion spread to anterolateral perilaryngeal structures. To conclude, US is not suggested as the method of choice in patients with laryngeal neoplasms. However, in subjects with advanced tumors, also US can image the lesion directly, and even detect tumor spread to surrounding tissues, especially in the anterior and lateral directions. In a few cases, this can contribute to preoperative staging and to select the correct therapeutic approach.
