Objective:To explore the long-term effect of rhinoplasty of nasal cavity improving nasal obstruction in patients with structural variation. Method:One hundred and six patients with structural rhinitis included this study whose assessment of nasal obstruction were achieved by visual analogue scale(VAS), and were divided into two groups: group1(n=56,VAS score >5), group 2(n=48,VAS score <5).They were measured by rhinomanometry and acoustic rhinometry recording the minimum cross-sectional area of nasal cavity(MCA), the distances from the nostrils(MD) and the nasal volume of 5 cm,2-5 cm,5-7 cm from the nostril(V5,V2-5,V5-7),then we calculated the ratio of the parameters of the two sides of the nasal cavity respectively, recorded nasal resistance and calculated Rlr. All patients were performed endoscopic rhinoplasty of nasal cavity and re-evaluated one-year later. Two groups were compared with statistical test.Result: The symptoms of twogroup patients improved satisfactorily after surgery. VAS scores and ratio of pre-operation of two groups had statistical differences except MD,V5-7,and group1 had more structural abnormalities compared with group 2.VAS scores and ratio of pre- and post-operation of group1 had statistically difference. Conclusion:Severity of nasal obstruction is related to structural variation of nasal cavity and the nasal plasty has certain clinical application value as its good long-term curative effects,the purpose of surgery is to restore symmetry of nasal cavity.
