Nasal bone repositioning should ideally be performed no later than 2 weeks after the injury, and the procedure is the primary treatment for nasal bone fractures. Nasal bone fractures are common in clinical practice and are called open nasal bone fractures if there is an open laceration wound on the back of the nose. Usually an emergency surgery is required, with debridement and suturing performed simultaneously with nasal bone repositioning. If there is no open wound on the back of the nose, it is called a closed nasal fracture. For closed nasal fractures, there are usually two optimal time periods for clinical nasal bone repositioning. First, within a few hours after the trauma occurs, that is, before the soft tissues of the nose have had time to swell and bruise. Secondly, 7-14 days after the trauma need the soft tissue swelling to fully subside. However, there are clinical cases in which nasal bone repositioning is performed about 1 month after trauma for various reasons.
