[Maxillary sinusitis in children: clinical and diagnostic aspects].

Acute or chronic sinusitis is often overlooked and poorly understood in the pediatric population as many children have frequent episodes of upper respiratory infections that confuse accurate diagnosis. The authors present a prospective study in 89 children with clinical and radiographic presence of maxillary sinusitis in order to underline the most frequent clinical symptoms and signs and the most significant diagnostic procedures that help confirm precise definition of this common disease. The authors also discuss the relationship with allergic factors, clinical causes of poor sinus drainage, and environmental factors that may increase the possibility of sinus infection.
