What Causes Sinusitis in Children?

Chronic sinusitis primarily results from recurrent episodes of acute sinusitis, as well as factors such as malnutrition, poor immune resistance, and congenital adenoid hypertrophy. The most common complication in children is acute sinusitis, which manifests with symptoms including purulent nasal discharge, headache, and purulent rhinorrhea. Additionally, patients may experience localized sinus pain, periorbital edema, and cellulitis secondary to acute inflammatory infection.
