Are Craniofacial Asymmetries Related to Trunk Asymmetries?

Abstract

The aim of this study was to investigate whether craniofacial asymmetries could be a predictor of spine asymmetries or not. Female individuals aged between 18 and 25 years participated in this cross-sectional descriptive-analytic study. The angle of trunk rotation was measured by a scoliometer in conjunction with the Adams forward-bending test. Individuals in the control group (n = 57) had spinal curvature of 0 to 3 degrees, and individuals in the study group (n = 53) had spinal curvature of between 4 and 6 degrees. Facial anthropometric measurements of individuals were evaluated by referencing anatomical landmarks determined on the face with 2-dimensional photogrammetry using ImageJ (Version 1.53q) program. Both groups were similar in terms of facial measurements (P > 0.05). Axial trunk rotation values of the mid-thoracic and thoraco-lumbar regions were significantly higher on both sides of the asymmetry group (P < 0.05). The distances between facial landmarks are not associated with asymmetries of spine regions (P > 0.05). Although the sensitivity and predictive value of facial asymmetries in determining trunk asymmetries and sagittal spinal posture were low, it was concluded that comparative studies are needed, especially in individuals with asymmetry at the level of scoliosis, as the asymmetries of the individuals in our study were not at the level of scoliosis.
