Abstract

BACKGROUND AND OBJECTIVES
We aimed to evaluate the effects of septal deviation on patient symptoms and acoustic rhinometry measurements in patients with allergic rhinitis and to determine which side of the septum is the better choice.
MATERIALS AND METHODS
The bilateral nasal provocation test with acoustic rhinometry was performed on patients with septal deviation and allergic rhinitis (Group A, n=25) and in patients with allergic rhinitis alone (Group B, n=26). Fifteen to 60 minutes after provocation, the change in symptoms as measured by the visual analogue scale, the change in total nasal volume (TNV) and minimal cross-sectional area (MCA) were compared between the concave and convex septal sides. The degrees of change in TNV and MCA were also compared between the groups.
RESULTS
Group A had higher basal values and more changes in nasal obstruction than did Group B. Changes in TNV and MCA were most prominent after 30 minutes on both sides, without significant differences. By summing the sides together, we were able to obtain more stable results without paradoxical increase.
CONCLUSION
Septal deviation itself has little effect on the result of nasal provocation in patients with allergic rhinitis. By summing the parameters of acoustic rhinometry from both nasal cavities, clinicians can achieve more stable results.
