title: A universal way to evaluate the curve in rhinomanometry.
abstract: A new way to evaluate the curve of nasal airway resistance has been developed. With polar coordinates, all curves can be described. Also, tightly closed or wide open noses can be compared with angles. The method is of value in clinical as well as in scientific work, especially when dealing with statistics.
