There are few studies that consider the degree of nasal septal deviation. Our aim in this study is to analyze the holistic relationship between nasal septal deviation and facial asymmetry in 3D.
Material and Methods: The tomography images of the patients were evaluated together with axial, coronal and sagittal sections by 3D and multiplanar reformatted. Patients with a vertical and axial septal deviation angle of 5 degrees and above were selected for our study. One hundred patients were randomly selected, facial width (between maxillo-zigion), right/left lateral projection (between porion-maxillozigion), right/left length (between zygomaticofrontal suture-gonion) in millimeters (mm); the septal deviation angle in the vertical and axial planes was measured in degrees.
Results: According to morphological analysis; a statistically significant relationship was shown between septum deviation and facial asymmetry (p<0.05). A positive correlation was found between both vertical deviation angle and axial deviation angle and facial width and projection (p<0.05). The facial width was found to be greater and the length shorter on the side of the deviation compared to the contralateral side (p<0.05).
Conclusion: In our study, it was shown that there is a relationship between nasal septal deviation and facial asymmetry. We suggest that a 3-dimensional evaluation should be performed when evaluating facial asymmetry. It is important to evaluate patients with facial asymmetry correctly before surgery, to make expectations more realistic and to predict possible results.
