Abstract
Objectives: This study aims to evaluate the relationship between nasal parameters and sagittal skeletal malocclusions while considering gender differences.
Material and Method: A calculated sample size of 75 adult subjects was included in this cross-sectional study based on inclusion criteria of age between 16-30 years seeking orthodontic treatment. Nasal parameters were evaluated clinically using the nasal index, classifying noses into three shapes: Leptorhinne, Platyrhinne, and Mesorhinne. Skeletal malocclusions were categorized as Class I, Class II, or Class III based on the ANB angle on the lateral cephalogram. Statistical tests included chi-square tests and post-stratification chi-square tests to explore the correlation between nose morphology, gender, and skeletal malocclusions.
Result: The sample size comprises 56% females and 44% males. There was no significant relationship between skeletal malocclusion and nose shape. One-way ANOVA indicated significant differences in Nose Depth (p value 0.031*) and Horizontal Distance between PRN and STPog parallel to HP (p value 0.000*) among skeletal malocclusion groups. Post hoc analysis confirmed significant variations in Nose Depth and Horizontal Distance between specific malocclusion groups. However, no significant differences were observed in Upper Nose Length, Nasal Height, or Lower Nose Length among these groups.
Conclusion: The nose shape has no relation to skeletal malocclusion and gender of subjects. Skeletal Class III has more deeper nose depth as compared to Class II malocclusion. Horizontal distance was greater in Skeletal Class II malocclusion in comparison to Class I and Class III malocclusion.
