Is There a Relationship Between Vertical Facial Development And Nasal Cavity?
1Istanbul Aydın University Orthodontics Istanbul Turkey.
Background:
There are no studies investigating the relationship between cone beam computed tomography (CBCT) and nasal passage findings and vertical facial development. The aim of this study is to determine the relationship between nasal cavity anatomy and vertical development of patients.
Methods:
A total of 60 CBCTs were examined, and Class I malocclusion individuals were divided into two groups (30 each) according to vertical facial development. All nasal cavity findings were recorded in the study. Vertical facial development, nasal septum, nasal cavity width, thickness and angle were evaluated. Mann-Whitney U Test was used, and Student's t test was used for the comparison of two groups with normal distribution. Significance was evaluated at p<0.01 and p<0.05 levels.
Results:
Statistical analysis showed a relationship between vertical facial development and nasal cavity findings. Nasal septum deviation was mild to moderate in the hyperdivergent group, while septal deviation was absent in the hypodivergent group. A statistically significant difference was found in the width, distance (x-y) and angle of the nasal cavity from the hyperdivergent group in Class I vertical subgroups (p<0.05).
Conclusion:
When compared between low-angle and high-angle groups, statistically significant differences were observed in anterior face height, nasal passage angle, and distance between the outermost points of the nasal cavity.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
