To evaluate helical computed tomography (CT) scanning in patients with laryngeal deviation. ⋯ Three-dimensional images of the laryngeal cartilages and bones, 3D airway surface models, and sequential coronal and axial CT scans were obtained using helical CT. This method allows the 3D observation of laryngeal deviation, and viewing of images from various directions on the computer was useful to understand the characteristics of laryngeal deviation.
