Changes in nasal obstruction, nasal airway resistance, and postoperative nose appearance were evaluated in 92 rhinoplasty patients. Fifty-six patients had a deviation of their nose from the midline preoperatively. They were improved according to rhinomanometry whether the rhinoplasty was combined with a functional septoplasty or with a submucous resection. Among the other 36 patients who did not have a deviation of the nose from the midline, 23 had a rhinoplasty combined with a functional septoplasty and 13 had no surgery on the septum at all. Rhinomanometrically, only patients operated on with the combined operation were improved; the rest became worse, even in terms of nasal obstruction. Among 58 patients from both groups with preoperative nasal obstruction, there was agreement for 76 percent between the subjective and rhinomanometric changes. The advantages of giving the rhinomanometric results in a polar coordinate system are discussed.
