There is clinical evidence for impaired lung function in chronic rhinosinusitis with nasal polyps (CRSwNP) patients, which may be due to a high incidence of asthma comorbidity. The lung function characteristics of non‐asthmatic CRSwNP patients are not known. Small airway dysfunction (SAD) is involved in the pathogenesis of asthma. However, whether SAD is detected in non‐asthmatic patients with CRSwNPs remains unclear.

伴有鼻息肉的非哮喘性慢性鼻-鼻窦炎小气道功能受损

有临床证据表明慢性鼻窦炎伴鼻息肉 (CRSwNP) 患者的肺功能受损，这可能是由于哮喘合并症的高发率。非哮喘性 CRSwNP 患者的肺功能特征尚不清楚。小气道功能障碍（SAD）与哮喘的发病机制有关。然而，在患有 CRSwNPs 的非哮喘患者中是否检测到 SAD 尚不清楚。
