Deviated nasal septum

Normal nasal septum and a deviated septum, with views of both looking at head tilted back showing nostrils and at front of face.

The nasal septum is the wall between the nostrils that separates the nasal passages. The septum is made of cartilage and thin bone. If the nasal septum is crooked, it is called a deviated nasal septum. A deviated septum may be caused by injury or surgery to the nose.

A deviated nasal septum may not cause symptoms. When present, symptoms may include a crooked nose, noisy breathing, or trouble breathing through the nose (especially on one side).
