Rhinosinusitis is a common diagnosis encountered by providers of all disciplines. Pediatric acute and chronic rhinosinusitis account for up to 2% of the total annual visits to the outpatient clinics and emergency departments. Once correct diagnosis is made, appropriate treatment measures can be initiated. It is important to recognize rhinosinusitis in children due to the potential serious complications and the impact it may have on quality of life of those children. Medical management is the mainstay of treatment, and, fortunately, it is successful in most of those children. When medical management fails, or a complication occurs, surgery may be required.
