From 2003 to 2004, 83 patients （166 sides） with nasal septum deviation were treated in our hospital, including 38 receiving submucous resection of nasal septum （SRNS） and 45 receiving submucous resection of nasal septum plus unilateral or bilateral partial inferior turbinectomy （SRNS＋U/B PIT）. All patients were tested by Eccovision acoustic rhinometry before and 6 months after operation to assess the treatment effect. It was found that total nasal cavity was bigger in the patients receiving SRNS＋U/B PIT than in those receiving SRNS alone （P〈0.05）. It was also found that patients receiving SRNS had unsatisfactory and unstable outcomes. Therefore, it is suggested that patients suffering from deviation of nasal septum （caused by chronic hypertrophic rhinitis） should receive SRNS＋U/B PIT. In order to standardize this surgical procedure, we named this operation as ＂nasal modification＂; the operation indications and principles of it should be established and completed.
