Deviated nasal septum

Dr Henry Knipe and Assoc Prof Frank Gaillard et al.

Deviated nasal septums are a common, usually incidental, finding seen on brain and paranasal sinus CT studies. They are commonly seen with external nose deformities. 

Symptomatic patients can present with unilateral nasal obstruction or less commonly epistaxis, obstructive sinusitis, and/or pain/pressure symptoms 4

Nasal septum deviation 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 or turbinate hypertrophy with septal deviation being towards the contralateral side.

Unrecognised nasal septal deviations can contribute to failed rhinoplasty 3

Nasal septal deviation can be C-shaped, reverse C-shaped, S-shaped or reverse S-shaped 3

If medical management fails, the most common surgical procedure performed is septoplasty 4.5
