ObjectiveTo evaluate the surgical effect for nasal diseasescombined asthma, and to discuss the significance of nasal function examination in the diagnosis and treatment.MethodsAccording to the combined diseases, the asthma patients were divided into nasal septum group, nasal polyps group, and sinusitis group. The surgical effect, improvement of nasal ventilation function and relief of asthma were evaluated and compared across groups via nasal function examination combined with the improved asthma control questionnaire (ACQ6).ResultsThe nasal function examination showed significant postoperative changes in all groups. The differences of nasal function change between the nasal septum group and nasal polyps group, sinusitis group were statistically significant (P<0.05), while that between the nasal polyps group and the sinusitis group was insignificant (P>0.05). Statistical results of ACQ6 showed significant differences between the scores before and after operation in all groups, which indicated that asthma symptoms got relieved after operation（P<0.05）. And the group comparison results are not statistically significant(P>0.05).ConclusionsSymptoms of asthma can be relieved significantly via surgical treatment of accompanied nasal diseases. Combined application of nasal function examination and ACQ6 may provide a new strategy for the diagnosis and treatment of nasal diseasescombined asthma.
