Abstract:
Objectives:
The aim of this study was to examine the relationship between vertical direction differences and the nasal cavity in skeletal Class I individuals.
Materials and Methods:
This study was divided into 2 groups according to the vertical direction angle, and it was conducted on a total of 60 individuals with skeletal Class
I features, with 30 individuals in each subgroup. Angular and millimetric measurements (N-ANS, ANS-ME, N-ME, Ba-N/Ptm-Gn°, nasal septum,
nasal cavity width (NCL), nasal cavity angle° (NCA)) were made in accordance with the parameters determined on cone beam computed
tomography (CBCT) before the treatment of the individuals constituting the research groups. In a retrospective study, the relationship between
vertical skeletal development of the nasal cavity on CBCT images was examined in detail. The Mann-Whitney U test was used, and Student's t test
was used to compare two groups with a normal distribution. Spearman's correlation analysis was used to determine the relationship between
quantitative data.
Results:
In the comparison of Class I vertical direction subgroups, a statistically significant difference was found in terms of measurement values ANS-Me
and N-Me, nasal cavity width and angular measurements (p<0.001) According to the results of the Mann-Whitney U test, men had significantly
higher measurements of the sex and nasal cavity than women (p = 0.001; p<0.001).
Conclusion:
Class I individuals with different vertical direction dimensions were affected by changes in the nasal cavity during vertical development.
