CRS remains a common challenging clinical entity due to variable phenotypes with different underlying mechanisms that lead to persistence or recurrence polyps. The eosinophils dominant inflammation was considered as a major pathological hallmark and challenges of CRS with nasal polyps (CRSwNP). Differentiate surgical approaches towards eosinophilic CRSwNP (eCRSwNP) should be addressed on the basis of the inflammatory endotypes. eCRSwNP has been recognized as the most easily relapsed type of CRS, and the combination of asthma increases the difficulty of treatment. Till now there is no recognized surgical strategy for eCRSwNP with asthma.
