1. The causes of crooked nose are congenital dysplasia, acquired dysplasia and deflection caused by trauma. Some patients with crooked nose have crooked nasal cartilage and some have crooked nasal bones. If the deviated nose is caused by trauma, it must be six months to one year later, and the local tissue hyperplasia of the trauma has stabilized before the deviated nose can be corrected.

2, the type of serious bending of the bridge of the nose. When the nose is not bent seriously, in order not to break the nasal bone and make the curved bridge of the nose look straight, cartilage or dermal fat will be transplanted on the bridge of the nose, or a prosthesis will be placed to make the invaginated part protrude and eliminate the protruding part to correct the crooked nose.

3, low nose bridge will be ideal when correcting curved nose and raising nose bridge. When cutting off the nasal bone can't achieve the ideal effect, or the nose is seriously bent, it is necessary to break the nasal bone first and then correct the shape. When the nasal bone and cartilage are seriously bent to one side, it can be corrected by moving the protruding part and the concave part inward with a scalpel or osteotome.
