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 256 pediatric patients (152 males and 135 females, aged between 2 and 15 yr), 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.
