ABSTRACT
Pediatric sinusitis is a very common disease that otolaryngologists and primary care physicians see in their offices. The exact incidence of sinusitis is unknown due to lack of precise definition and diagnostic criteria that can give us the appropriate incidence. It is, however, very well known that about 0.5 to 5% of all upper respiratory tract infections (URI) are complicated by sinusitis (1). The average child has between six and eight URIs per year, making sinusitis a common problem in the pediatric population (1). The incidence is on the rise, especially in developed countries, because of the increased incidence of allergic rhinitis. In 1994, Wright estimated that about 42% of children in the United States have allergic rhinitis by the age of six years (2).
