... ardization of Rhinomanometry, on 40 patients. Thirty healthy adult volunteers participated belonged to the control group. None of the patients or healthy volunteers had previous history of nasal surgery or active rhinological disease. Results: The post-operative improvement in symptoms of nasal obstruction obtained in 92,5% patients and improvement parameters of the active anterior rhinomanometry in 42,5% patients. Conclusion: The correlation between the findings with rhinomanometry and subjective sensation of nasal patency remains uncertain. There still seems to be only a limited argument for the use of rhinomanometry for quantifying surgical results. Three months postoperative findings are very early results to interpret the permanent effects.
