Acute Bone Remodeling after Reduction of Nasal Bone Fracture on Computed Tomography Imaging

BACKGROUND A number of studies have reported complication after reduction of nasal bone fractures. Among complicated cases, some showed improvement in shape of the nose with passage of time. Therefore, we examined these changes using computed tomography (CT) images taken over intervals. METHODS CT scans of 50 patients with new nasal bone fractures were reviewed, and the images were compared amongst preoperative, immediately postoperative, and one month scans. Changes in nasal bone shape, were evaluated based on the angle of nasal bone arch between the nasal bone and frontal process of maxilla, overall shape of arch, mal-alignment of fracture segments involving bony irregularity or bony displacement. These evaluations were used to separate postoperative outcomes into 5 groups: excellent, good, fair, poor, and very poor. RESULTS Immediate postoperative nasal shape was excellent in 10 cases, good in 31 cases, fair in 8 cases, and poor results in a single case. Postoperative shape at one month was excellent in 37 cases, good in 12 cases, fair in a single case. CONCLUSION The overall shape of nasal bone after fracture reduction tended to improve with passage of time.
