[Comparison of active foreign flow rhinomanometry (oscillation method) and active personal flow rhinomanometry in 17 patients before and after correction of the nasal septum].

The nasal resistance of 17 patients with nasal septum deviation was measured before and after septum correction using two active rhinomanometric methods; the one with external flow (oscillation method), the other with spontaneous flow. Both methods correlated closely (p less than 0.01). The oscillation method proved to be as reliable and sensitive as the spontaneous flow method and less strenuous for the patient. Conventional rhinomanometric methods have failed especially in children because of their great demands on the patient's compliance; thus the oscillation method serves to increase the clinical application of rhinomanometry.
