The treatment of a deviated nasal septum primarily depends on the severity of the condition. If it is a minor deviation without noticeable clinical symptoms, most people can simply be observed and may not require specific treatment. However, if the deviation is significant and accompanied by clinical symptoms, such as frequent poor nasal ventilation, particularly blocked nostrils on the deviated side, as well as possible nosebleeds or headaches, surgery might be considered. Currently, corrective surgery for a deviated nasal septum under endoscopy is a minimally invasive procedure. Although there are certain risks associated with the surgery, the overall risk is not high. After surgical treatment, most patients are able to recover normally.
