Introduce the crooked nose plastic surgery in detail.
A perfect nose is what many people dream of, but some people's noses are not satisfactory, and some people's noses are crooked, which is what we usually call crooked noses. Deviated nose deformity is a compound deformity of bone and cartilage, which not only affects the appearance, but also affects the nasal ventilation function with the distortion of nasal septum. In order to obtain good postoperative results, these deformities should be corrected at the same time during operation. If the nasal curvature deformity is not serious and there is no ventilation obstacle, cartilage transplantation can only be used to correct the asymmetric deformity of the external nose. Generally, the distortion of nasal septum cartilage is corrected first, and then the external nasal deformity is corrected after a period of time.

The formation of deviated nose deformity is closely related to obvious or inconspicuous local trauma in fetal or growing period. Developing children are very sensitive to trauma, but the reaction is light, and there may be only slight bleeding. The injury is mainly cartilage contusion. Its long-term reaction is that cartilage development is unbalanced, which is characterized by asymmetric development of cartilage-bone connection and excessive development of damaged nasal bone, which can cause excessive growth, distortion or local expansion of cartilage tissue; The dislocation of bone and cartilage can cause excessive soft tissue on one side or relative defect on the other side; Long-term deviated nose deformity can also lead to bilateral nostril asymmetry. Acute trauma in adulthood, although there is no asymmetric deformity in the early stage, but the depressed fracture of the nasal bone can cause distortion of the bridge of the nose in the later stage.

Once the cartilage of nasal septum is twisted, it can't be corrected only by the twisted part. The way to correct this deformity is to reshape the deformed cartilage to make it straight, or to cover the sunken bridge of the nose indirectly. Most deviated nose deformities need to be corrected directly by surgery, and only a few deviated nose deformities (such as slight deviated nose deformity and no nasal dysfunction) can be corrected indirectly, such as local cartilage transplantation. To correct airway obstruction, we must correct the distortion of nasal septum cartilage and make it straight on the basis of maintaining normal supporting function and local anatomical structure.
