背景：喉部和下咽部的拓扑学特征可以在颈部超声检查中显示出来，尽管超声在诊断上的重要性很小。不同程度的甲状软骨骨化似乎是主要的限制因素。我们的目的是评估超声检查的可及性喉结构与高端分辨率超声设备。方法和患者我们检查了101例患者内镜和超声。考虑到甲状软骨骨化的局限性，检查和分析了正常喉的发现和病理。结果尽管骨化程度不同，但超声仍能清晰显示喉内大部分结构。老年人的骨化增加。16例病例（16%）因骨化而无法成功评估。在9例恶性肿瘤和1例喉囊肿中，超声评估能够提供额外的诊断信息。结论：喉部超声检查需要操作者有系统的经验，但即使存在甲状软骨骨化，也能够描绘相关的解剖结构，从而能够提高诊断效果，并可能节省额外的成像方式。
BACKGROUND Topological features of the larynx and hypopharynx may be depicted during sonographic examination of the neck, although ultrasound is seen of minor diagnostic importance. The varying extend of thyroid cartilage ossification appears to be the major limiting factor. We intended to assess the sonographic accessability of laryngeal structures with high end resolution ultrasound devices. METHODS AND PATIENTS We examined 101 patients endoscopically and by ultrasound. Normal laryngeal findings and pathologies were examined and analysed considering limitations by thyroid cartilage ossification. RESULTS Despite varying grades of ossification, the majority of laryngeal structures were clearly displayed by ultrasound. Ossification was increasing in the elderly. In 16 cases (16 %) ossification prevented a successful evaluation. In 9 cases of malignant tumor and one laryngocele sonographic assessment was able to contribute additional diagnostic information. CONCLUSIONS Ultrasound of the larynx requires methodical experience of the operator but is capable to depict relevant anatomic structures, even with presence of thyroid cartilage ossification, thus being able to increase diagnostic impact and may save additional imaging modalities.
