A retrospective review of children diagnosed and treated for suppurative complications of paranasal sinusitis was undertaken to describe clinical presentation, microbiology, and treatment. This review includes children with subgaleal abscess and osteomyelitis of the frontal bone, subdural empyema, frontal lobe abscess, meningitis, and encephalitis. Staphylococcus aureus and group C beta-hemolytic Streptococcus were isolated agents. All children were treated with intravenous antibiotics with drainage of both the sinus and extracranial and intracranial suppurations. Results of treatment in the series support the opinion that combined aggressive surgical and antibiotic treatment is a preferred method in complicated sinusitis in children.
