Deviated nasal septum refers to the deviation of nasal septum cartilage and bone tissues towards one or both nasal cavities, causing symptoms such as nasal congestion, nosebleeds, and even headaches. Generally speaking, when these symptoms of nasal septum deviation occur, surgical treatment is typically adopted. This involves correcting and removing the deviated cartilage and bone tissues under endoscopic guidance to restore normal airflow in the nasal passages.

If a patient only has structural or radiographic evidence of a deviated nasal septum but lacks clinical symptoms, surgery may not be necessary. Alternatively, temporary observation and medical management to control inflammation of the nasal mucosa can be considered.
