This report presents 2 children (boys, 11 and 9 years old) who had post-traumatic nasal septal abscesses. Cultures for aerobic and anaerobic bacteria revealed Peptostreptococcus magnus and a ß-lactamase—producing Prevotella intermedia in the first patient, and Peptostreptococcus anaerobius, Streptococcus intermedius, and Prevotella melaninogenica in the second patient. Anaerobic bacteria may play a role in nasal septal abscesses.
