Intracranial complications of pediatric sinusitis: Identifying risk factors associated with prolonged clinical course

Frontal sinus involvement, and anaerobic and polymicrobial sinus cultures were predictive of a more severe infection requiring more surgical interventions, prolonged intravenous antibiotic treatment and overall hospital length of stay. Streptococcus pneumoniae was not prevalent in our series, and there seems to be a shift in the microbial profile of this patient subset, compared to previous studies, which can likely be attributed to the adoption of pneumococcal vaccinations. Sinus cultures were more predictive of a complicated clinical course compared to intracranial cultures, suggesting the importance of a thorough sinus debridement and obtaining directed sinus cultures.
