Trauma can lead to a deviated septum, which may be broken, fractured, or misaligned under violent impact or compression. Traumatic septal deviation may result in nasal congestion, headaches, and nosebleeds. In some patients, septoplasty is required to correct the deformity and remove the symptoms to restore normal nasal function. The disease mostly occurs in childhood, and the history of trauma is often forgotten. Because the parts that make up the nasal septum are still in the developmental stage, the nasal symptoms are not obvious in childhood. As the septum grows and ossifies with age, nasal septal deviation occurs. In adults, nasal trauma can also result in septal deviation or dislocation of the septal cartilage. A crooked nose is formed when all septal cartilage segments are deviated and tilted to one side. It is recommended that patients with nasal trauma should pay attention to it, and it is recommended that CT examination should be performed to clarify the condition and standardize the treatment.
