For 24-hour symptoms of nasal fracture, patients with nasal fracture usually show local swelling and pain. In severe cases, ventilation dysfunction may occur and affect the normal aesthetic appearance, and some patients may experience nasal bleeding, which are the 24-hour symptoms of nasal fracture. The diagnosis of nasal fracture is mainly based on physical examination and auxiliary tests, such as general X-ray and local CT. For the treatment of nasal fracture, if the fracture is well located, does not affect the ventilation function and does not affect the aesthetic appearance, conservative treatment is usually chosen actively. In the case of nasal bone collapse, which affects the normal ventilation function and the normal aesthetic appearance, it is necessary to actively perform repositioning and filling surgery. If the patient has high requirements for appearance, plastic incision and repositioning can be considered. The best time for surgery is 7-10 days after the injury.
