[Computer-assisted rhinomanometry (CAR)]

We developed a software program for computer-aided rhinomanometry (CAR) to assess the nasal resistance curve before calculating the rhinomanometrical parameters. This program forms the basis for correct processing of data in diseases associated with nasal obstruction. We were able to demonstrate the superiority of CAR over the conventional averaging of the resistance curves in 246 measurements. Thus computer-aided rhinomanometry opens up a wide range of diagnostic possibilities.
