Deviated septum

The symptoms

The causes

Deviated septum

A deviated septum occurs when the thin wall (nasal septum) between the nostrils shifts to one side. In many people, the nasal septum is off-center or deviated, making the nostril smaller. When nasal septum deviation is severe, it can block part of the nose and reduce airflow, making it difficult to breathe. Further exposure of a deviated nasal septum to the drying effect of airflow through the nose can sometimes contribute to crusting or bleeding in some people. A nasal blockage or congestion (obstruction) can occur from a deviated nasal septum, inflammation of the tissues lining the nose, or both. Treatment of nasal obstruction may include medications to reduce inflammation or nasal dilators to help open the nostrils. Surgery represents the definitive solution to correct a deviated septum.
