What is a deviated septum?

The nasal septum, which is composed of bone and cartilage, divides the nostrils and the nasal cavity into right and left portions. It is usually straight at birth and sometimes bends as the result of a birth injury. The nasal septum is usually straight throughout childhood, but as a person ages the septum tends to bend towards one side or the other. This deviated septum may make breathing difficult by obstructing the nasal cavity.
