A deviated nasal septum can be treated. Firstly, it is necessary to examine the degree of deviation and the clinical symptoms. If it is a simple deviation with mild severity and no related clinical symptoms, this condition generally does not require special treatment and regular follow-ups are sufficient. However, if the deviation is severe and accompanied by corresponding clinical symptoms such as nasal congestion, runny nose, headaches, dizziness, and nosebleeds, surgery may be considered to correct the deviation. Generally, after surgical correction, the deviated nasal septum can be cured.
