The nasal bone repositioning procedure is mainly applied to nasal bone fractures. The main way to reposition the nasal bone is to insert the nasal bone repositioner into the bilateral nasal cavity to reposition the collapsed and displaced nasal cartilage. Since the nasal bones are mainly made up of cartilage, the nasal shape can be fully restored at that time after repositioning, but symptomatic anti-inflammatory treatment is required for 5 days after surgery. At the same time, the postoperative nasal cavity should be filled with Vaseline gauze or expansion sponge, and the filling can usually be removed about 3 days after surgery, so the patient can be completely healed in 5 days after surgery. If the patient also has a fracture of the nasal septum, postoperative attention should be paid to the ventilation of the nasal cavity, and if necessary, corrective surgery of the deviated septum should be performed. After nasal bone repositioning, attention should be paid to avoid touching the nose with force for 3 months to prevent bumping the nose.
