Inflammation of paranasal sinuses:the clinical pattern is age-dependent.

Acute rhinosinusitis (ARS) represents a common disorder, associated with consistent morbidity as well as with a large prescription of antibiotics. ARS has a significant impact on clinical practice; it usually presents with respiratory complaints persisting longer than 10 days and showing no signs of improvement. Throughout the evaluation of pediatric patients with ARS confirmed by nasal endoscopy, we have been able to provide evidence that age has a significant influence on clinical patterns in children with ARS.
