title: Childhood sinusitis.
abstract: Childhood sinusitis is difficult to diagnose. It is classified on the basis of duration of inflammation--acute or chronic--and cause of inflammation--infectious or noninfectious. Infectious sinusitis is often a result of obstruction of the osteomeatal complex. Inflammation in noninfectious sinusitis is similar to the inflammatory changes detected in respiratory mucosa of patients with asthma. Acute sinusitis is primarily an infectious process similar to a prolonged infection of the upper respiratory tract. Plain radiography has limited value for the diagnosis of acute sinusitis in children. The most effective treatment of acute sinusitis is administration of a beta-lactamase-resistant antibiotic. Chronic sinusitis may be infectious, noninfectious, or both. Coronal computed tomography of the sinuses and nasal endoscopy are the preferred methods for determining the presence of chronic sinusitis. When physicians prescribe therapy for chronic sinusitis, they need to consider whether the underlying cause is infectious, noninfectious, or both. Treatment of chronic infectious sinusitis is most effective when a beta-lactamase-resistant antibiotic is administered. Chronic noninfectious sinusitis may respond to topically intranasally applied corticosteroids. If medical treatment fails to resolve the disease within 3 months, surgical intervention may be necessary. Finally, although an association between asthma and sinusitis exists, a cause-and-effect relationship has not been established.
