Whether or not surgery is needed for a deviated nasal septum ultimately depends on the individual's specific symptoms and the extent of the deviation. This condition, which is a very common congenital developmental abnormality, can also be caused by postnatal trauma. Deviations are very common in the human body, but not everyone requires surgery.

The diagnosis of a deviated nasal septum mainly considers whether the extent of the deviation affects function or appearance, that is, whether it causes pathological changes. If the nasal septum deviation does not cause functional changes or affect appearance, then surgery is not necessary.

If it causes nasal congestion or leads to complications such as rhinitis or sinusitis, or affects appearance, then surgical treatment should be considered. Therefore, whether surgery is needed for a deviated nasal septum should be based on the severity and the presence of related clinical symptoms.
