title: Comparison of Odiosoft-Rhino and rhinomanometry in evaluation of nasal patency.
abstract: OBJECTIVE
  To conduct a preliminary study testing the validity of the Odiosoft-Rhino (OR) in the evaluation of nasal patency in patients with nasal septal deviation and compare the results with visual analogue score (VAS) of nasal obstruction and rhinomanometry (RMM).
  
  
  METHODS
  OR and RMM were performed on 68 patients with nasal septal deviation and 61 healthy controls. VAS, nasal resistance values and nasal sound analysis were noted for the left and right nasal cavities.
  
  
  RESULTS
  There are statistically significant differences between VAS, RMM and nasal endoscopic findings between the patient and the control group. The OR results at expiratory and inspiratory 2000 - 4000 Hz and 4000 - 6000 Hz intervals for both nasal cavities show a statistically significant difference between the patient and control groups. Nasal endoscopic findings, RMM, OR results of the deviated sides in the 2000 - 4000 Hz interval correlate well with VAS.
  
  
  CONCLUSIONS
  OR may be a practical test in assessment of nasal patency. OR at the 2000 - 4000 Hz interval shows a correlation with VAS. However, showing a correlation between a test and a variable is not the same as proving that it is a useful diagnostic test. Therefore, more studies with larger series are needed.
