Abstract: Chronic rhinosinusitis(CRS)has traditionally been classified as T-helper(Th)2 type inflammation(type 2 inflammation)with recruitment of predominantly eosinophils or as a Th1/Th17 type inflammation with predominantly neutrophils. These two inflammatory processes have long been thought of as being mutually exclusive in CRS. However, recent studies have found that neutrophilic(NEU)and eosinophilic(EOS)infiltrates increased significantly and influenced each other in the nasal mucosa or nasal polyp tissue in severe CRS. In this review, we examined the recent investigations into this mixed NEU/EOS inflammation in CRS in terms of cellular interactions and the implications on possible clinical treatment strategies.

Key words: Chronic rhinosinusitis, Neutrophil, Eosinophil, Endotype, Treatment
