Inflammatory cell predominance and patterns in chronic rhinosinusitis with and without nasal polyposis patients

摘要

Objectives There is interest in identifying chronic rhinosinusitis (CRS) endotypes that align pathophysiology with clinical observation and outcomes. CRS with polyps (CRSwNP) has classically been studied with reference to tissue eosinophilia, but the role of other cellular infiltrates remains uncharacterized. No particular tissue prognosticators have been described for CRS without nasal polyps (CRSsNP). Predominance of leukocytes seen in surgical tissue may be useful for differentiating CRS subtypes, severity of inflammation, and outcomes.
