[Rhinomanometric measurements in obstructed nasal respiration before and following rhinosurgical interventions].

355 patients with nasal obstruction caused by different disease were treated by various nasal operations. Active anterior rhinomanometry was performed before and after operation, both before and after decongestion of the nasal mucosa. 254 patients were reassessed 6 to 9 months later. On average an increase of nasal airway was achieved from V 1.5 = 0.46 1/s before operation to 0.74 1/s after operation (before decongestion) and from V 1.5 = 0.55 1/s before operation to 0.83 1/s after operation (after decongestion of the nasal mucosa). The decongestion effect and the differences between the better worse nasal cavities showed a significant decrease after operation. Rhinomanometric evaluation of the various nasal operations is presented for patients with nasal blockade caused by various diseases.
