Active anterior rhinomanometry in pre- and postoperative evaluation, use of Broms' mathematical model

The authors studied the value of the Broms' mathematical model for active anterior rhinomanometry in a pathological population. They compared all different variables of a pathological group with a normal group and found significant differences for v0, v2 and R. There existed no difference between the means of v0 before and after surgery. There existed, however, a strongly positive correlation between the expiration and inspiration value. The influence of surgery was always significant for the variables v1, v2, v3 and R. Furthermore, the absolute deviation between the computed values and the recorded values tended to be very small. So, the authors concluded that rhinomanometry is a valuable aid in judging pre- and postoperative results.
