Objective: To discuss the clinical use of nasal airflow measurement in septoplasty.
Method: After nasal decongestion, 21 patients's nasal airway resistance and nasal airflow were evaluated by anterior rhinomanometry before and after submucous resection of nasal septum.
Result: The amount of nasal airflow asymmetry could show nasal respiratory function better than nasal airway resistance does, the patients with absolute amount of nasal airflow asymmetry greater than 50% had bad postoperative outcome, patients' satisfication with operation was significantly correlated with the presence of post-operative symmetrical nasal airflow.
Conclusion: The amount of nasal airflow asymmetry can serve as an indicator of patient selection, outcome evaluation and prognosis in nasal septum deviation.
