If the nasal cartilage is really injured, it will not be deformed because it is very soft and elastic. However, it is necessary to pay attention to whether there is a nasal bone or maxillary frontal process fracture. The frontal process of nasal bone and maxilla is divided into two parts. On the lateral X-ray film of nasal bone, the fracture may be missed because of the overlapping relationship between left and right. Need to be examined by an otolaryngologist. If there is a feeling of rubbing the bone, a suspected fracture, and no problem with the nasal bone photos, you need to do nasal bone CT. The thickness of nasal bone CT scan is very thin, and subtle fractures can also be found.
