[Clinical characteristics of non-eosinophilic and eosinophilic chronic sinusitis with nasal polyps]

Objective:To investigate the clinical characteristics of non-eosinophilic and eosinophilic chronic sinusitis with nasal polyps.Method:Ninty-two patients with chronic sinusitis with nasal polyps were collected and divided into eosinophilic chronic sinusitis with nasal polyps(EOS CRSwNP) and non-eosinophilic chronic sinusitis with nasal polyps(NONEOS CRSwNP) by pathological classification. The clinical characteristics between the two types were compared. Result:NONEOS CRSwNP is more common in northern area of Fujian province(84.8%). NONEOS CRSwNP had the following clinical characteristics: one most nasal discharge was purulent; two more pyocysts can be seen in nasal polyps; three the proportion of eosinophils in the peripheral blood was mostly normal. Four mainly maxillary sinus lesions. EOS CRSwNP had the following characteristics: one most nasal discharge was mucous purulent; two bilateral sinus lesions were more common, mainly ethmoid sinus lesions; three the proportion of blood eosinophilic cells in peripheral blood was often increased. Ouroften accompanied by asthma, postoperative nasal polyps are prone to relapse, systemic steroid hormone is effective in the treatment of recurrent polyps.Conclusion:There are differences in clinical characteristics between eosinophilic and non-eosinophilic chronic sinusitis with nasal polyps. The ratio of eosinophils in peripheral blood, preoperative endoscopy and CT evaluation are helpful for the classification of chronic sinusitis with nasal polyps.
