Evaluation of nasal obstruction may consist of a physical examination, rhinoscopy with adequate light and a nasal speculum, chemical analysis, imaging studies, and rhinomanometry. Chemical analysis may include neutrophil counts relating to the presence of infection, eosinophil counts in allergic conditions, and mast cell counts in food allergy. Imaging studies include CT scans and MRI. Rhinomanometric techniques include passive, active, and acoustic methods.
