Skew of nasal bone is a kind of deformity of nose, which may be caused by teacher's injury or acquired factors. Skew of nasal bone has a certain influence on growth and beauty, so how to correct it? Skew of nasal bone is the main cause of crooked nose. According to professional rhinoplasty doctors, the distortion of bones is complicated, including uplift, depression and distortion. Now, taking the nose deformation caused by the collapse of nasal bone due to the untimely correction of nasal trauma as an example, this paper introduces its correction methods. Other distortions in different situations can be corrected according to the different lesions. How to correct nasal bone skew? 1. Half-lying position, skin disinfection. 2. Incision: make an arc incision on the sunken nasal vestibule and alar cartilage, and then insert a small scissors or a double-edged knife to separate the soft tissue on the nasal bone. 3. Saw off the collapsed nasal bone. Saw off both sides of the collapsed nasal bone with a nasal saw to make it move freely. This step can also be done with a nose chisel. 4. Use a crowbar to pry up the broken nasal bone in the nasal cavity, and fill the nasal cavity with iodoform gauze to prevent collapse. 5. The external fixation is molded with proofing glue and fixed outside the nose. The correction of nasal bone deviation should be combined with personal facial characteristics: different shapes of deviation need different treatment methods. The skew of the lower part of the bridge of the nose is caused by cartilage skew. It is only necessary to correct the crooked cartilage, cut off the connection between the cartilage of nasal septum and the vertical plate of ethmoid bone, vomerous bone and lateral nasal cartilage, remove the redundant lateral nasal cartilage and restore the neutral position of nasal septum. The nasal cavity must be filled with iodoform gauze for 5-7 days after operation to maintain the position of the nasal septum after repair. This operation can be performed under local anesthesia in outpatient department, and only oral antibiotics are needed after operation. The skew of the middle part of the bridge of the nose is caused by the skew of the nasal bone. It is necessary to cut off the middle sides of the nasal bone and the nasal bone at the junction of the nasal bone and the maxilla, cut off the connection between the cartilage of the nasal septum and the vertical plate of the ethmoid bone, and reset the nasal bone. At the same time, the deflection of the diaphragm can be corrected. This operation requires general anesthesia in the hospital. After operation, the nasal cavity should be stuffed with iodoform gauze for 5 -7 days and fixed with plaster to maintain the position after reduction. I need intravenous antibiotics for 3 days. If the bridge of the nose collapses, this crooked nose can be leveled by implanting a prosthesis, which is also to correct the adjustment skew of the bridge of the nose.
