The nose is protruding from the center of the face and is susceptible to trauma caused by impact or fall. The size, degree and direction of the external force vary and the degree of injury varies, which can be manifested as soft tissue contusion, laceration, nasal bone fracture, septal fracture, cartilage dislocation, etc. Early manifestations include local pain, nasal bleeding, nasal obstruction, local swelling, subcutaneous petechial hemorrhage, nasal bridge deviation or collapse, etc. The presence of nasal trauma should be seen immediately at the hospital, and CT examination should be performed to clarify the location and severity of the injury. There are two best times to treat nasal trauma: 1. 7-20 days after trauma. At this time, the acute edema of the nose gradually decreases and the nasal deformity becomes more obvious, so the nasal bone fracture can be reset to correct the skewed nasal bone and the skewed fractured nasal septum cartilage can also be corrected to some extent. It should be emphasized that anatomical repositioning of the nasal bone fracture is important not only to greatly improve the patient’s appearance, but also to avoid the injury and pain caused by secondary surgery, therefore, it is recommended to perform it under general anesthesia. In this way, the patient is basically painless and the doctor’s disposition is more in place. 2.After six months of trauma. At this time, the nasal deformity has basically been stabilized, and the nasal bone osteotomy and correction of nasal septal cartilage can be performed under general anesthesia to improve the appearance and nasal ventilation. In short, after nasal trauma, it is important to firmly grasp the best time for treatment to avoid delaying the condition.
