Facial and periorbital cellulitis in children.

Facial and periorbital cellulitis require emergent recognition and treatment. Hemophilus influenzae type B is the most common pathogen, with Streptococcus pneumoniae being cultured less frequently. Infections following injury are usually caused by Staphylococcus aureus and group A streptococci. Initial evaluation must exclude more severe orbital involvement. Appropriate bacteriological specimens should be obtained. Management requires parenteral antibiotics and careful monitoring for a clinical response or dissemination to other sites of infection.
