Objective measurements of nasal-airway patency have been difficult, and in the past limited to research situations. A new instrument, the rhinoresistometer, has been developed to measure nasal-airway resistance. This instrument, utilizing a new concept, is simple and has promise as a device that can be adapted to the clinical evaluation of patients with nasal obstruction. It was found to be a sensitive instrument for recording changes in nasal-airway resistance.
