Paradoxical nasal obstruction.
The phenomenon of paradoxical nasal obstruction is described. An understanding of this phenomenon is made possible by the knowledge of the nasal cycle and of the concept of total nasal airway resistance. These topics are reviewed and two patients with paradoxical nasal obstruction are described. Direct observation, rhinomanometric tests and serial tomograms were utilized to substantiate these findings.
