Because of its anterior location and prominence, the nose is susceptible to injury when subjected to external forces. According to the degree and type of injury, it can be divided into soft tissue injury of the nose, nasal bone fracture and fracture of adjacent maxilla, orbital bone and skull base bone. External nasal soft tissue trauma For lighter cases of simple contusions of the skin and soft tissues, no special treatment can be done. For severe cases, cold compresses can be applied early to control the development of hematoma, and hot compresses can be applied after 24 hours to promote the absorption of bruises and the decreasing of swelling. For open wounds, wound debridement and suture surgery should be performed at the hospital as soon as possible, and tetanus antitoxin should be injected routinely. If there is a tissue defect, depending on the location and size of the defect, a flap graft is required if necessary. Nasal bone fracture Nasal bone CT can determine the presence of a nasal bone fracture and the displacement of the fractured bone to guide the subsequent treatment. No special treatment is required for simple nasal bone fractures without displacement; nasal bone fractures with external nasal deformities should be surgically repositioned after the swelling has subsided. Surgery should preferably be performed within 10 days after the injury; beyond 2 weeks, the formation of bone scabs poses certain difficulties for the repositioning. Those with complex lesions such as sinus, periorbital, maxillary or skull base fractures should be treated early with timely, reasonable and effective treatment, conservative or surgical depending on the situation, to reduce the harm caused by the injury. If a nasal fracture is not treated in a timely manner, it will form a deformed healing, affecting the appearance and possibly affecting nasal ventilation and olfactory function. In practice, most patients will have fractures of the nasal septal cartilage and nasal septum bone, which will affect the ventilation and drainage of the nasal cavity, and it is best to perform both nasal bone fracture repositioning and nasal septal deviation correction.
