CEPHALOMETRIC GRAPHICAL EVALUATION OF THE EXACT LOCATION OF TRANSVERSE MAXILLOFACIAL DISCREPANCIES

Summary/Abstract: Objective: To develop and apply a novel diagnostic graphical model for analyzing frontal cephalometric radiographs in order to determine the exact location of a maxillofacial asymmetry.Material and methods: Standard frontal cephalometric radiographs of 64 patients with visible craniomandibular asymmetry were taken. Known cephalometric points were used and the midsagittal line was built using the Sassouni method. The evaluation of the grade of severity of the facial asymmetry is based on the research of Buranostidporn et al. To identify the exact location of the maxillofacial asymmetry, more bilateral points than the ones known from the literature are required. In order to determine the symmetry of a facial contour where there are no known bilateral points, we elaborated our own independent graphic model – the Concentric Arcs Method.Results: The analysis of our sample of patients with our own independent Concentric Arcs Method found that 51,5% of them have both mandibular and maxillary asymmetry, whereas 48,5% of the patients have only mandibular asymmetry. We evaluated the grade of severity of the facial asymmetry. We establish the distribution of the studied 64 patients, depending on the three degrees of facial asymmetry.Conclusion: The created graphic method and applied on frontal cephalometric radiographs estimates the exact location of facial asymmetry, facilitates determining whether the reason for these discrepancies is to be found in the maxilla and/or the mandible, and offers a basis for setting limit values of the severity degree of transverse maxillofacial discrepancies.
