A nasal provocation test is the most reliable diagnostic test to confirm allergen in allergic rhinitis. However, there are neither specific objective methods nor a standardized method and interpretation. In 20 normal subjects and 86 allergic rhinitis patients, we applied acoustic rhinometry as a new objective method to assess changes in nasal patency induced by nasal allergen challenge, a procedure which is used for confirming allergic rhinitis. The result shows that a minimal cross-sectional area (MCA) and volume from the nose tip on back to 7 cm (nasal cavity volume) after allergen challenge were significantly decreased in allergic rhinitis patients in comparison with the control subjects. We conclude that acoustic rhinometry can provide a sensitive index for evaluating the results of a nasal provocation test.
