- Abstract: BACKGROUND: We conducted this study to analyze the values of the key cephalometric angular measurements of the mandible using 3-dimensional (3D) computed tomography scans. METHODS: In the 106 enrolled patients, a 3D cephalometric analysis was performed to measure the angular variables of the mandible. These values were compared between the two sides and between the two sexes. RESULTS: The frontal measurements revealed that the mandibular body curve angle was larger on the left (Lt) side (right [Rt], 141.24+/-7.54; Lt, 142.68+/-6.94; P=0.002) and the gonial angle was larger on the right side (Rt, 134.37+/-8.44; Lt, 131.54+/-7.14; P<0.001). The sagittal measurements showed that the gonial angle was larger on the right side (Rt, 134.37+/-8.44; Lt, 131.54+/-7.14; P>0.05). Further, the transverse measurements revealed that the mandibular body curve angle was larger on the right side (Rt, 140.28+/-7.05; Lt, 137.56+/-6.23; P<0.001). CONCLUSIONS: These results provide an average of the mandibular angular measurements for the Korean population, establishing a standard for determining surgical patient groups and outcome evaluations in the field of mandible contour surgery.
