In patients with congenital deviated septum, it usually does not get worse without surgery. However, if it is caused by acquired trauma or other diseases, it may become more and more severe without surgery. Most of the deviated septum is formed by congenital developmental abnormalities, while some patients are formed by nasal trauma causing septal fracture, or nasal tumor compression and other factors. Congenital deviation of the septum will stabilize in adulthood, so patients with congenital deviation of the septum will also have stable symptoms thereafter. In contrast, in patients with nasal septal deviation caused by nasal trauma or tumor, the septal deviation may become more and more severe as the condition progresses, and the symptoms of nasal congestion, runny nose, nasal bleeding, headache and dizziness will further aggravate. Therefore, it is recommended to actively treat the primary disease and to perform septal deviation correction surgery in parallel. In addition, patients with deviated septum should pay attention to keep the nasal cavity moist in daily life, do not dig the nostrils with your hands, do not blow the nose with force, and avoid excessive force when sneezing.
