Correct the crooked nose, re-coordinate the proportion of five senses, and reproduce the delicate nose. The nose occupies the commanding height of the face, and it is more vulnerable to trauma besides its unique advantages. Therefore, in addition to congenital reasons, most of the skew of the bridge of the nose is caused by the lack of effective treatment after nasal trauma. In addition, the operation of nasal bone fracture will be accompanied by serious secondary deformation, especially the injury of nasal septum in childhood, which may be accompanied by aquiline nose. The clinical manifestations of nasal bridge deviation can be divided into nasal bone bending, cartilage bending or nasal bone cartilage bending at the same time, of which nasal septum bending is the most common. According to the bending shape, it can be divided into C-type, S-type, and serpentine shape with the whole alar biased to one side. The C-type and S-type nasal tips are in the nasal midline, but the snake-shaped nasal tips are inclined to one side. The deviated nose deformity is a compound deformity, which seriously affects the face. The nasal septum of patients with deviated nose is twisted, which affects the nasal ventilation function, so if the nasal dorsum is twisted or tilted to one side, it can be corrected by deviated nose plastic surgery. The cartilage and bone of nasal septum should be preserved as much as possible during treatment. Because the nasal septum is the main support of the nasal dorsum, in some cases, it is also the cartilage donor area for subsequent operations. Severe deviated nose and nasal congestion need to remove the whole nasal septum, then cut and splice the nasal septum cartilage and replant it as a free cartilage piece. When the nose is not seriously bent, in order not to break the nasal bone and make the bent nose look straight, cartilage or dermal fat will be transplanted on the bridge of the nose, or a prosthesis will be implanted in the concave part of the rhinoplasty to eliminate the convex part to correct the crooked nose. At the same time, people with low nose bridge will be ideal to correct the crooked nose while augmentation rhinoplasty.
