The decision is mainly based on the severity of the deviation. If it is just a simple nasal septum deviation and not particularly severe, and there are no obvious clinical symptoms, then treatment is not necessary. Most patients may not have clear symptoms, and the deviation is often discovered during a physical examination or through a nasal endoscopy; in such cases, specific medication or surgery is not required. However, if the deviation is particularly severe and accompanied by obvious clinical symptoms such as nasal congestion, runny nose, induced sinusitis, headaches, or nasal bleeding, it is advisable to consider corrective surgery under nasal endoscopy. This procedure is minimally invasive, and the general recovery period is about a week, and the overall results are relatively clear.
