The voluntary control of nasal airway resistance.
The effects of flaring and constricting the alar margins upon nasal airway resistance (NAR) were measured in 24 normal subjects. The median decrease in NAR on flaring was 21% whilst constricting increased NAR by a median of 67%, there being a high inter-subject variation. We feel these movements of the alar margin an important factor in controlling NAR.
