ABSTRACT
Acute and chronic rhinosinusitis represent some of the most prevalent disorders encountered by physicians in ambulatory care environments and are among the most common diagnoses for which antibiotics are prescribed [1,2]. The high prevalence of this disease accounts for a large contribution of health-care resource consumption and costs, and yet the incidence of this disorder seems to be increasing [3,4]. Because the etiology and pathophysiology remain obscure, rhinosinusitis poses a considerable challenge for physicians in the overall management of the problem.
