OBJECTIVES: This study was undertaken to evaluate the aerobic and anaerobic microbiology of acute maxillary sinusitis of odontogenic origin presenting with periodontal infection in children.
METHODS: Aspirates of 18 acutely infected maxillary sinuses that were associated with odontogenic infection in children who presented with periorbital cellulitis were processed for aerobic and anaerobic bacteria.
RESULTS: A total of 54 isolates were recovered (3.0 per specimen): 13 aerobic and facultative (0.7 per specimen) and 41 anaerobic (2.3 per specimen). The number of isolates per specimen varied from 1 to 4. Aerobic and facultative organisms alone were recovered in 2 specimens (11%), anaerobes only in 7 (39%), and mixed aerobic and anaerobic bacteria in 9 (50%). The predominant aerobic and facultative organisms were alpha-hemolytic streptococci (4), microaerophilic streptococci (3), and Streptococcus pyogenes and Staphylococcus aureus (2 each). The predominant anaerobic bacteria were anaerobic gram-negative bacilli (17), Peptostreptococcus spp (11), Fusobacterium spp (8), and Propionibacterium acnes (2). Twelve beta-lactamase-producing bacteria were recovered from 9 specimens (50%).
CONCLUSIONS: This study demonstrates the unique aerobic and anaerobic microbiological features of acute maxillary sinusitis of odontogenic origin presenting with periorbital cellulitis in children.
