A deviated nasal septum does not necessarily require surgery. The treatment for a deviated nasal septum mainly depends on the severity of the deviation and clinical symptoms. If it's just a minor deviation without obvious clinical manifestations, most patients don't need specific treatment. Generally, they can just be rechecked in the near future to observe any changes. However, if the deviation is significant and accompanied by clinical symptoms, such as nasal congestion, nosebleeds, runny nose, headaches, or dizziness, surgery might need to be considered. Currently, the surgery can be conducted under endoscopy as a nasal septum deviation correction surgery or as a nasal septoplasty. Overall, the surgery is not very traumatic, and generally, the results are quite definitive. Typically, the recovery period is about two weeks.
