Functional biomechanics of laryngeal cartilages and soft tissues is difficult to visualize by MRI and CT. The aim of the study was to visualize and compare skeletal structures and soft tissues in detail by MRI and CT. 20 human cadaveric larynges were examined by MRI and CT and visualized by post-process imaging software. In all 20 human cadaveric larynges, the laryngeal cartilages could be visualized clearly. The assessment of the thyroid and cricoid is dependent of the ossification. The ossification of the hyaline cartilages increases with advanced age where male larynges ossify more than female larynges.
