Figure 1

Axial-view computed tomography images from patient 1. (a) The narrowing of glossopharynx (blue double-headed arrows) evident before uvulopalatopharyngoplasty (UPPP) was caused by the impression of large tonsils (asterisk). (b) The narrowing was enlarged transversely; however, the glossopharynx became narrower in the anteroposterior direction after UPPP (indicated by the number). The lines on midsagittal view indicate the level of the axial-view.
