Nasal bone deformities are usually divided into two types: one is the nasal bone shape deviation caused by fresh nasal bone fracture. Second, old nasal bone deviation. For nasal bone skew caused by fresh nasal bone fracture, it is suggested to improve the corresponding three-dimensional CT of nasal bone as soon as possible to know whether there is nasal bone dislocation and comminuted fracture, and whether it is necessary to give nasal bone reduction in time to correct nasal shape. For old nasal bone deviation, it may be related to past trauma or congenital reasons. For the old nasal bone deviation, that is, more than 1 month, it is difficult to achieve a satisfactory nasal shape after nasal bone reduction. Therefore, it is recommended to go to the plastic surgery department for nose modification and corresponding plastic surgery.
