FUCINI, M.C. et al. Craniofacial asymmetry: radiographic analysis in the frontal and transverse planes in subjects aged 18 to 22 years of both sexes. Rev Esp Cirug Oral y Maxilofac [online]. 2009, vol.31, n.1, pp.17-23. ISSN 2173-9161.

The aim of this study was to determine the type and magnitude of craniofacial asymmetry by multiplanar cephalometric analysis. The sample comprised 207 subjects of both sexes aged 18 to 22 years, who were radiographed in the frontal plane at posteroanterior incidence. Three separate acetate tracings were made on the same radiograph based on three planar structures: A (superficial), B (intermediate), C (deep). A virtual midline was traced. Real midlines were overlapped and compared with the virtual midline to determine the type and magnitude of the deviation on each plane. The subjects were radiographed on the transverse plane. Three separate acetate tracings were made on the same radiograph based on three planar structures: A (orbital), B (maxillary superior), C (maxillary inferior). A virtual midline was traced and compared with the real midline. Frontal plane: Results indicated a greater frequency of right deviation in the three planes, B being the plane with the largest percentage of deviation (type and magnitude) compared to C and A. Transverse plane: Results indicated a greater frequency of left deviation in the three planes, C being the plane with the largest percentage of deviation (type and magnitude) compared to B and A. These results show that craniofacial asymmetry was widespread and emphasize the importance of its study in the detection of craniofacial growth pathology.
