If the patient’s nose is swollen and he wants to know if there is a fracture, he can first look in the mirror himself to see if there is any obvious distortion of the bridge of the nose or any obvious collapse of the nasal bone, and sometimes there may be an obvious bone rubbing sensation when he touches the fractured area. If you want to determine whether there is a fracture or not, the most accurate method is for the patient to go to the hospital and take a 3D CT of the nasal bone, so that you can clearly see whether there is a fracture line formation or not, and sometimes there is only a slight crack or a problem of continuous interruption of the bone. In severe cases, there may be an angular deformity of the nasal bone, and such patients are often considered for surgery to deal with the nasal bone fracture after active swelling reduction. It is best to protect the nose from external impact.
