Since the nose is located in the center of the face, the nasal bone is often fractured after trauma caused by car accidents, fights, and other injuries. The appearance may be characterized by a deviated nose, which may be accompanied by impaired ventilation. After a nasal trauma, a CT scan is recommended to determine the location and severity of the injury. The best time to treat nasal trauma is twofold: 1) 5-10 days after the trauma, when the acute edema of the nose gradually subsides, you can carry out manipulative repositioning to correct the deviated nasal bone; 2) half a year after the trauma, you can carry out the correction of nasal septal cartilage and osteotomy of the nasal bone to improve the appearance of the nose and improve nasal ventilation.
