The nasal septum is the wall that separates the left and right nostrils. A centered septum allows air to flow equally through each nostril. In a deviated nasal septum, the wall is not centered.

Most people will not require treatment. In severe cases, surgery may be needed. Surgery on the septum alone is called
septoplasty. It relieves nasal blockage by centering the septum between the 2 nostrils.
Sometimes surgery to reshape the nose (rhinoplasty) is performed at the same time. The 2 procedures together are called septorhinoplasty. Children who need surgery usually wait until they have stopped growing, around age 16.
To help prevent a deviated septum:
- Wear seat belts in automobiles and airplanes
- Wear appropriate protective headgear when playing sports
