The method for prediction of asthma in patients with polypous rhinosinusitis was developed. It consists of determination of the average mass molecules (AMM, optical density units), measurement of exhaled and inhaled air temperature (T exh, ºC), and (T inh, ºC), and determination of the temperature difference (ΔT, ºC) between the inhaled and exhaled air temperatures and with the help of the discriminant equation: D = +5.028 × T exh - 0.405×ΔT - 8.910 × AMM, where the discriminant function (D) boundary value is 152.16. At D greater than or equal to the discriminant function boundary value, the absence of asthma in patients with polypous rhinosinusitis is predicted; at D less than the discriminant function boundary value, the development of asthma is predicted.
