title: Infection of the facial area, oral cavity, oropharynx, and retropharynx.
abstract: Radiologists play an important role in the evaluation of upper neck infections. Although most oral cavity infections arise from diseased teeth, several other sources of infection need to be considered. The distinction between abscess and phlegmon is of particular importance. Cross-sectional imaging is frequently used to identify complications of the initial infection.
