Introduction Concha bullosa (CB) is the most common sinonasal anatomical variation
reported in literature, it occurs most often in the middle turbinate. Causes of development
are not clearly identified but coincident prevalence with deviated nasal septum (DS)
is common.
Objective:
To study the relationship between DS and development of CB.
Methods:
A prospective study including 40 patients with DS, CT scans were thoroughly analyzed
to detect the presence of CB, its type, and laterality. Effect of degree of septal
deviation from the midline and level of deviation in the axial plane were also addressed.
Results:
The study included 40 patients with DS; 15 of them had associated CB; the lamellar
type of CB was the most prevalent followed by the true type.
Conclusion:
Incidence of CB was higher in patients with increased angle of septal deviation and
with lower level of deviation in the axial plane.
