Abstract:
OBJECTIVE: The purpose of this study was to compare the right and left differences of frontal ramal inclination in chin-deviated individuals. METHODS: Thirty adult patients with clinically apparent chin deviation were selected as the chin-deviated group, and 30 adult patients with symmetric faces were selected as the control group. On the posteroanterior cephalograms, the frontal ramal inclination was measured, and the right and left differences were compared and analyzed. RESULTS: While the control group did not show right and left differences of frontal ramal inclinations, the chin-deviated individuals showed right and left differences of frontal ramal inclination. In chin-deviated individuals, the frontal ramal inclinations of the non-deviated side were statistically greater than those of the deviated side. The right and left differences of frontal ramal inclinations, with menton deviation and the right and left differences of maxillary heights showed statistically significant correlation. CONCLUSION: We conclude that the frontal ramal inclinations should be considered in the diagnosis of facial asymmetry.
