title: [The relation between minimal cross section and subjective nasal obstruction].
abstract: Acoustic rhinometry is a new technique that is rapid, reproducible, non-invasive and requires minimal subject cooperation. Many authors think that the method is most reliable in measurements of the anterior nasal cavity. The objective of this study was to determine if a cross section of less than 0.4 cm2 is associated with severe nasal obstruction.
