Figure 3. Case 2. Three-dimensional computed tomography images of the sagittal view (A) and the epiglottis and larynx observed from behind (B). (A) The space from the mouth to the larynx is shown to be narrow (1). In contrast, the nasopharyngeal tract is maintained relatively wide, and the space behind the epiglottis is wide (2) in comparison with case 1. (B) The shape of the epiglottis is shown clearly. No distortion is observed.
