Abstract: Objective: To observe the effect of septoplasty and partial turbinectomy on the peak flow of nose,and to evaluate the value of the peak flow of nose in the diagnosis of the nasal chronic diseases.Methods: The peak flow of septoplasty and partial turbinectomy pre-and post-operation was measured using Mini Wright peak flow meter.Results: The peak flow of nose in normal adults was stable before and after 4 weeks.The peak flow of nose in the patients who were performed with septoplasty was increased to the normal level after operation.There are significant differences between pre-and post-operation (P<0.01).The peak flow of nose in the patients who were performed with partial turbinectomy was increased to the normal level as well after operation.There was significant difference between pre-and post-operation (P<0.01).Conclusions: Septoplasty and partial turbinectomy can increase the peak flow of nose significantly and improve the nasal airway function.
