The nasal septum is the wall in the nose that separates the left side of the nose from the right. The nasal septum is deviated when it is bent more to one side than the other, which can lead to difficulty breathing through the nose on the obstructed side. Deviation of the nasal septum can be congenital, or is the common result of a broken nose.
If the nasal congestion cannot be managed medically, or if the deviation is too significant, the nasal septum needs to be moved back to the middle with a surgical procedure. This surgery is done entirely through the nose, does not require any external incisions, and will not affect the external shape or appearance of the nose. If appropriate, this surgery can often be performed in conjunction with endoscopic sinus surgery.
