A deviated septum is a common condition that involves a displacement of the septum, the wall that separates the nostrils, to one side of the nose. About 80 percent of people have a deviated septum, which often develops as a result of an injury to the nose. This condition makes one nasal passage smaller than the other, which can affect breathing if the displacement is great enough.
Patients with a severely deviated septum may experience nasal congestion, nosebleeds, and frequent or recurring sinus infections as a result of their uneven nasal passages. Those with only minor displacement may not even be aware that they have a deviated septum and experience no symptoms.
Treatment for a deviated septum can vary depending on the severity of the condition and the symptoms associated. For most patients, this condition can be managed through decongestants and antihistamines that aim to reduce nasal congestion. For more severe cases, surgery may be required to correct the displacement. Surgery involves a procedure called a septoplasty to reposition the septum in the center of the nose.
