Abstract
The pathogenesis of chronic sinusitis is complex, involving a variety of inflammatory cells and inflammatory mediators, and neutrophils play a key role in the pathological process of chronic sinusitis. Understanding the molecular basis of the pathogenesis of CRS is helpful for the precise diagnosis and treatment of chronic sinusitis. This article will systematically review the mechanism of neutrophils in the inflammatory response of the body, their role in the pathogenesis and treatment progress in CRS, and look forward to future research directions.
