Active anterior rhinomanometry is used most commonly for evaluating nasal airway patency because of its easy, noninvasive application. A visual analogue scale (VAS) is generally used for evaluating the sensation of nasal patency. We studied the relationship between nasal airway resistance (NAR) and VAS score for sensation of nasal patency. Subjects were 14 adult volunteers who gave informed consent. They were divided by age into those 50 or younger and those over 50 years of age. After 10 minutes of rest seated, each subject was measured for NAR and VAS scores before nasal application of oxymetazoline (OXY) or sodium nitroprusside (SNP), a nitric oxide donor. Measurements were repeated 5 and 10 minutes after nasal drug application. We did not test the effects of OXY and SNP on individual subjects on the same day.Mean value of NAR in those aged less than 50 or less was higher than in those over 50. No significant correlation was seen between NAR and VAS score in subjects overalls, but a definite positive correlation was seen between NAR and VAS score in individual subjects aged 50 or less. No correlation was seen between NAR and VAS score recorded during nasal membrane swelling induced by local application of SNP. A positive correlation between NAR and VAS score was recorded during nasal membrane shrinkage induced by OXY application.These results suggested that the VAS is useful for evaluating the sensation of nasal patency, and that VAS correlate with NRA in subjects aged less than 50. There are several limitations for practical use of this method to evaluate the sensation of nasal patency, such as objects, age, and changes in nasal patency.
