Objective:To compare the outcomes of simultaneous versus staged nasal bone reduction and septoplasty in the treatment of traumatic nasal bone fractures with associated septal fractures. Methods:Patients with traumatic nasal bone fractures, with or without septal fractures, were recruited from two hospitals and divided into three groups. Group A underwent simultaneous nasal bone reduction and septoplasty, Group B underwent staged nasal bone reduction and septoplasty, and Group C underwent nasal bone reduction only. Nasal appearance scores and nasal congestion Visual Analogue Scale （VAS） scores were measured preoperatively, at 2 weeks postoperatively, and at 3 months postoperatively. For Group B, scores were also recorded at 2 weeks and 3 months after the second-stage surgery. Differences were analyzed using statistical software. Results:Two weeks post-surgery, the nasal appearance scores significantly decreased in all three groups compared to preoperative scores （P< 0.01）, with no statistically significant differences between the groups （P= 0.43, 0.71, 0.58）. In Group A, the VAS score for nasal congestion decreased significantly following simultaneous surgery （P<0.01）. In Group B, there were no significant differences in nasal congestion VAS scores between pre-surgery and post-first-stage, nor between three months post-first-stage and two weeks post-first-stage （P= 0.61, 0.13）. However, the VAS scores significantly decreased after the second-stage surgery compared to pre-surgery, and three months post-second-stage surgery compared to three months post-first-stage surgery （P<0.01）. The VAS scores for nasal congestion at two weeks post-surgery in Group A were lower than those in Group B after the first-stage surgery （P<0.01）. The incidence rates of nasal adhesions post-surgery in Groups A, B, and C were 0%, 6.9%, and 4.3%, respectively. Conclusion:For traumatic nasal bone fractures with associated septal fractures, performing simultaneous nasal bone reduction and septoplasty under general anesthesia using endoscopy is more time-efficient compared to staged surgery, and it results in a lower occurrence rate of post-surgical nasal adhesions.
