Chronic rhinosinusitis includes a heterogeneous group of conditions with differing pathophysiologies. Two main subgroups are described: with and without nasal polyps. Chronic rhinosinusitis without nasal polyps may be idiopathic or odontogenic or may be caused by immunodeficiency, vasculitis, or other autoimmune conditions. The majority of cases of chronic rhinosinusitis with nasal polyps are idiopathic but may also occur as part of genetic, metabolic, or immunologic diseases. The majority of white patients with chronic rhinosinusitis with nasal polyps have a type 2 pattern of inflammation, characterized by eosinophilia and elevated levels of interleukin-4, interleukin-5, and interleukin-13 cytokines. This finding may not apply to other racial groups, but further study is required.
