The crooked nose generally refers to the bending of the whole nose, the bending of the external nasal bones and cartilage and the bending of the nasal septum inside the nose. The bending of the internal nasal septum mainly has functional problems such as nasal congestion and rhinitis, while the bending of the external nasal septum mainly has some aesthetic effects, so we need to correct the crooked nose. Plastic rhinoplasty is an operation to peel off some cartilage along the nasal cartilage and correct the position. Plastic rhinoplasty is carried out through the edge of the nostril, so there will be no scar on the nose. According to the different conditions of cartilage or bone, cartilage plastic surgery can be performed separately or bone and cartilage plastic surgery can be performed at the same time. Antibiotics should be used after correction of deviated nose to avoid wound infection. The gauze for nasal congestion can be taken out within 1 ~ 2 days after correction of deviated nose; The proofing glue used to fix the external nose can be removed in 7 ~ 10 days; If it is found that the bridge of the nose is not in the center 3 ~ 4 days after the correction of the deviated nose, it can be moved to the center and fixed again, but the external nose should be prevented from being touched and pressed, causing the nasal bone to collapse again.
