Deviated nasal septum

A deviated nasal septum is a common incidental finding seen on brain and paranasal sinus CT studies.



It can be congenital or acquired. The most common acquired cause is trauma from motor vehicle collisions, sports-related injuries, and altercations.


Deviated nasal septa are commonly associated with concha bullosa with septal deviation being away from the concha.

There is no known association of deviated nasal septum and increased risk of sinusitis or a contributing factor in pathogenesis of chronic sinusitis.

Treatment and prognosis

Most common procedure performed is septoplasty.
