title: Identifying preoperative factors associated with the postoperative nasal synechia in patients undergoing closed reduction of the nasal bone fracture.
abstract: We conducted this study to identify preoperative factors that are associated with the postoperative nasal synechiae in patients with nasal bone fracture who underwent closed reduction.In the current single-center, retrospective study, we evaluated the fracture type, septal deviation angle (SDA), synechia scores (SSs) and visual analog scale (VAS) scores through a retrospective review of the medical records and computed tomography scans of 42 patients (n = 42) who had undergone closed reduction for nasal bone fracture at our medical institution during a period ranging from April to August 2013.The mean SS was significantly lower in the plane I group (n = 25) as compared with the plane II group (n = 17) (1.28 ± 1.77 vs 2.76 ± 1.89, P = 0.013). There was a significant positive correlation between the SDA and the SS with a formula of SS = 0.216SDA - 0.322 (r(2) = 0.532, P < 0.001) and between the SS and the VAS with a formula of VAS = 1.280SS + 0.612 (r(2) = 0.648, P < 0.001). Both the SS and VAS were significantly higher on the convex side as compared with the concave side of the nasal cavity.Our results indicate that patients with higher SDA or combined septal fractures might be at increased risks of developing the postoperative synechiae. Further large-scale, prospective studies are warranted to establish our results.
