Abstract Objective： To discuss the clinical effect of endoscopic sinus inferior turbinate boning and mucosa scratches minimally invasive volume reduction surgery to cure chronic hypertrophic rhinitis. Method： 90 patients with the clinical diagnosis of chronic hypertrophic rhinitis were randomly divided into two groups： the experiment group contained 45 cases accepted the inferior turbinate boning and mucosa scratches minimally invasive volume reduction surgery；the control group contained 45 cases accepted the operation of partial inferior turbinectomy. For a comparative analysis， they were observed for 6 months for clinical results and postoperative complications after operation. Then the saccharin test was carried out. The nasal mucociliary function at 3 months after operation and 6 months after operation was compared. Result： The difference of the clinical effect between the two groups was not statistically significant（ P>0.05）； the occurrence rate of operative complication of the experiment group was significantly lower than that of the control group（ P<0.05）； the mucociliary transport rate（ MTR） of the experiment group， before the operation and 3 months after operation and 6 months after operation， had no obviously changes（ P>0.05）， but that of the control group was obviously lower than pre-operation（on average， P<0.01）. The MTR of the control group was lower than that of the experiment group at 3 months after operation and 6 months after operation（ P<0.01）. Conclusion： Endoscopic sinus inferior turbinate boning and mucosa scratches minimally invasive volume reduction surgery is effective. It has fewer complications， which keeps the function of nasal mucosa and is consistent with clinical physiological function， so it is recommended.
