Rhinomanometry is well established as a useful clinical method for objective assessment of nasal patency. However, several expressions of nasal patency have been reported and complete standardization has never been accomplished.<BR>In this report, nasal resistances calculated from the equation R = ΔP/V at ΔP 100 Pa and at peak flow point, time averaged nasal resistance and integrated nasal patency were measured by a Rhinorheograph MPR-1100 and processed by a computer program, NI-101, in 350 adult patients. The values from the equation R = ΔP/V at ΔP100 Pa were slightly lower than those from the same equation at peak flow point or those from the time averaging method. The correlation line between the values of nasal resistance at peak flow point and the time averaged nasal resistance values was very close to the line of identity. No significant correlations were demonstrated between the values from the integrated nasal patency and the values from the other three expressions. We discussed the differences of the results from these expressions in this paper.
