So how to correct the extraosseous deviation of nasal beam? Let's ask the nasal plastic surgeon to introduce it. ? According to experts, the situation of nasal bone deviation can be divided into three types: the situation of nasal bone deviation is 1, and the type of deviation is also called simple deviation nose, which is defined as the deviation of nasal cartilage, that is, the lower part of the nose, and may also be accompanied by slight nasal bone deviation. Its characteristic is that the middle and lower part of the bridge of the nose deviates to the side of the central axis, and the tip of the nose is farthest from the central axis. Most of them are caused by congenital or childhood trauma. ? Type 2 and type C with skewed nasal bones are characterized in that the nasal root and tip are located on the axis, and the middle part of the nose bridge is bent into a C shape far from the central axis. ? Oblique nasal bones are type 3 and S, also known as complex deviated nose. Nasal cartilage and bone cone bend in different directions in an S shape. According to experts, the main method to treat nasal bone deviation is surgery, which is basically the same as rhinoplasty of camel nose, but some changes should be made according to different conditions of crooked nose. In the case of nasal bone deviation, manual reduction is generally used. Usually, the external deformation force includes the deviation of the nose cone, the involvement of the upper or lower lateral cartilage, and the deviation of the hard bone of the nasal septum, such as the pear-shaped bone, the vertical plate of the ethmoid bone, and the maxillary ridge. If we want to remove this external force, we can effectively correct the cartilage of nasal septum. On the contrary, it is easy to lead to the failure of nasal septum bone correction surgery and the distortion of nasal septum cartilage again. ? If it is caused by internal deformation, it may be that the nasal septum cartilage itself grows and develops at the same time, or it is distorted after injury. Generally speaking, this is mainly corrected by cutting off some deformed cartilage or using grafts and sutures. The procedure of nasal bone distortion correction is generally as follows: 1, nose cone; 2. Nasal septum; 3, nasal tip cartilage and nasal epidermis and soft tissue; 4. Suture and fixation. ?
