Although it is not a life-threatening condition, nasal obstruction can interfere with
the quality of life. After exclusion of septal deviations, the main structures
contributing to this problem are the nasal turbinates, especially the inferior turbi-
nates. Perennial allergic and nonallergic rhinitis are the most common non-
infectious causes of mucosal swelling of the inferior turbinates reducing nasal
air flow. Untreated, these conditions may result in permanent nasal obstruction
secondary to dilation of the venous sinuses or fibrosis.
