Abstract:Abstract: Objective?To investigate the comparison of clinical efficacy of the nasal endoscope assisted nasal vestibule incision and conventional open surgery treatment for traumatic deviated nasal deformity.?Methods?To screening 60 cases of patients from May 2013 to December 2018 with traumatic deviated nasal deformity as research subjects. 60 cases were divided into study group with 30 cases and control group with 30 cases. Patients in control group were given conventional open surgery treatment and patients in study group were given the nasal endoscope assisted nasal vestibule incision, then the two groups were compared in terms of clinical efficacy, relevant clinical indicators during treatment, postoperative complications, postoperative nasal resistance and external nasal measurement before and after surgery.?Results?The clinical efficacy in study group was higher than the control group (P?0.05); The relate clinical indexes in study group were better than the control group (P?0.05); The postoperative complications rate in study group was lower than the control group (P?0.05); The nasal resistance improvement in study group was better than the control group (P?0.05).?Conclusion?The nasal endoscope assisted nasal vestibule incisionin the treatment of traumatic deviated nasal deformityis significant, which is worthy of popularizationand application.
