Abstract: Rhinosinusitis affects millions of persons annually and has a marked impact on quality of life and work productivity. Chronic rhinosinusitis (CRS) is characterized by symptoms that last at least 12 weeks. The history and physical examination should include a search for underlying conditions, such as allergic or nonallergic rhinitis and nasal polyposis. An evaluation of underlying immunodeficiency is warranted in certain patients, particularly those with severe or difficult-to-treat disease or other recurrent infections. When radiologic evaluation is indicated, coronal sinus CT scanning is the procedure of choice. While antibiotics are indicated for bacte- rial rhinosinusitis, intranasal corticosteroids represent the mainstay of treatment for CRS and are particularly useful when polyp disease is present. Nasal irrigation with a saline solution can be a very beneficial adjunctive therapy. Depending on coexisting conditions, additional treatments may include antihistamines, leukotriene modifiers, and immunotherapy. (J Respir Dis. 2006;27(9):372-379)
