The decision of whether or not to perform surgery for a deviated septum caused by an external force is based on the patient’s physical condition and the degree of septal deviation. In children, the symptoms of nasal trauma are not obvious, and with age, septal deviation occurs as the septum grows and ossifies; in adults, nasal trauma can lead to septal deviation or dislocation of the septal cartilage. 1. If the degree of septal deviation caused by external force is mild, the shape of the nose does not change significantly, and nasal ventilation is not greatly affected, no special treatment can be carried out. 2. If the deviation of the nasal septum is obvious or the nasal ventilation is not smooth, then the main clinical corrective treatment is through surgery. Preoperative CT of the paranasal sinuses and related preoperative examinations should be perfected to exclude contraindications to surgery. In addition, if there is localized destruction of cartilage and mucosa, it is necessary to wait until it is completely healed before surgery. The deviation of nasal septum caused by external force should be consulted in time and treated according to the doctor’s prescription.
