On examination the nasal cavity should look abnormally spacious, lacking (part of) one or both turbinates (the inferior and/or middle turbinates). Mucosal pathology varies greatly. In some patients, the mucosa is dry and pale because of metaplasia; in others, it is red because of chronic infection. Crusting may range from absent to severe. The symptoms and findings are believed to be caused by abnormal aerodynamics, chronic inflammation and dryness leading to loss of airflow sensation that feels like dyspnea.
