Total serum immunoglobulin E and eosinophil counts were also compared. The severity of nasal diseases in these patients was assessed via the Lund\u2013Mackay score (LMS) and Lund\u2013Kennedy score (LKS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>There was no difference between the asthma and nonasthma groups in terms of total nasal resistance at 75 Pa (R<jats:sub>75T<\/jats:sub>), bilateral minimum cross\u2010sectional area (MCA<jats:sub>R+L<\/jats:sub>), or bilateral nasal cavity volume between 0 and 7.0 cm<jats:sup>3<\/jats:sup> (V7<jats:sub>R+L<\/jats:sub>). Forced expiratory volume in 1 second (FEV<jats:sub>1<\/jats:sub>) and forced expiratory flow between 25% and 75% of forced vital capacity (FEF<jats:sub>25\u201375<\/jats:sub>) of the asthma group were significantly lower than those of the nonasthma group. FEV<jats:sub>1<\/jats:sub> and FEF<jats:sub>25\u201375<\/jats:sub> were not correlated with R<jats:sub>75T<\/jats:sub>, MCA<jats:sub>R+L<\/jats:sub>, V7<jats:sub>R+L<\/jats:sub>, or severity of nasal disease.

In CRSwNP patients with asthma, impairment of upper airway patency was associated with changes in LMS and eosinophilia, and in these patients lower airway patency was significantly lower than that of the control group (without asthma). In CRSwNP patients with asthma, there was little or no association between upper and lower airway patency.
