OBJECTIVE: The aim of this study was to evaluate the

presence of deviated septum in individuals with different

skeletal malocclusions.

MATERIALS AND METHOD: The study was performed on

cone beam computed tomography images of a total of

159 individuals, 53 in each Class I, Class II, and Class

III skeletal malocclusion. Nasal septum deviation was

analysed in three groups as mild (type 1; <9°), moderate

(type 2; 9-15°), and severe (type3; >15°). In addition,

the presence of concha bullosa in different skeletal

malocclusions was evaluated. The data were analyzed

statistically using the Chi-square test and One-way

Analysis of Variance (ANOVA). The relationship between

skeletal malocclusions and types of deviation was

determined using Cramèr’s V analysis.

RESULTS: There are statistically significant differences

between type 2 and type 3 in individuals with Class

I skeletal malocclusion and between type 1 and type

3 in individuals with Class II skeletal malocclusion

(p=0.046; p<0.01 respectively). In individuals with Class

III skeletal malocclusion, no difference was observed

between deviation types. In addition, a weak correlation

was found between skeletal malocclusion and deviation

types (Cramèr’s V = 0.213). No significant difference was

observed between the groups in terms of concha bullosa

and deviation side (p=0.215).

CONCLUSION: Although a significant difference was

observed in terms of deviation type in individuals with

Class I and II skeletal malocclusion, a weak correlation

was observed between the increase in deviation severity

and skeletal malocclusions.
