To gain insight into patterns of presentation, imaging, microbiological aspects, therapy, disease course, and outcome of intracranial complications of sinusitis (ICS), which are challenging conditions with the potential to cause significant morbidity and mortality. We reviewed our experience with ICS in children and adolescents.Design: Consecutive case series with a mean follow-up of 12 months. Setting: Tertiary pediatric referral center. Patients: Consecutive sample of 25 children and adolescents treated for 35 intracranial complications (mean age, 13.2 years [range, 4-18 years]). Interventions: Medical and surgical management. Main Outcome Measures: Survival and temporary and permanent neurologic sequelae.Results: Most patients were adolescents (n=19; 76%) and male (n=19; 76%). Epidural abscess was most common (13 complications), followed by subdural empyema (n=9),
