Hello! My answer to your question is as follows: 1, depending on the intensity and direction of the nose injury at the moment. Nasal bone is the most prominent part of human face, with thin structure, which is easy to cause fracture when injured. Because the situation of violence is different and the degree of nasal bone fracture is different, it will show various image forms. Clinical manifestations: 1) nosebleeds: almost all nasal bone fractures have nasal mucosa tears and nosebleeds. 2) Local deformity: When the violence comes from one side, the ipsilateral nasal bone sinks and the contralateral nasal bone bulges, resulting in deviated nasal deformity. Frontal violence often causes bilateral nasal bone fractures, resulting in bridge collapse and saddle deformity. 2 ~ 4 hours after injury, the deformity was temporarily covered up by swelling and congestion of nasal soft tissue and eyelid. Accompanied by dislocation or fracture of nasal septum, nasal septum or nasal cartilage can be seen exposed. 2. It needs to be cultured for 2-3 weeks after operation (do not press). 3. The cost of nasal bone reduction surgery is generally 200-300 yuan, which varies from province to city. 4, nasal bone reduction surgery, generally can only restore the original state, but can not make the bridge of the nose more straight. Wish you all the best!
