A deviated nasal septum can be cured. Firstly, a deviated nasal septum generally arises congenitally or from trauma, leading to the deviation. Most patients have cartilage deviation, and a small portion have bony deviation. In terms of treatment, firstly it is necessary to evaluate the degree of deviation and the clinical symptoms. If it is just a minor deviation without significant clinical manifestations, treatment may not be necessary, and regular check-ups will suffice. However, if the clinical symptoms are noticeable and the degree of deviation is severe, then surgical correction should be considered. Currently, considering endoscopic septoplasty can achieve a cure.
