Graphic method to measure Articular Eminence Inclination. The mid-sagittal section of the condyle was separately extracted on the right and left. On the axial view, the section of the condylar process that had the widest mediolateral diameter was chosen as the reference view for reconstruction of the sagittal slices. In this section, a line orthogonal to the mediolateral diameter of the condyle and parallel to the long axis of the condylar process was drawn, so sagittal images were reconstructed as 0.5 mm slice interval/thickness and the most central one was taken. Legend: L1: line 1, a horizontal line, parallel to the Frankfurt plane (FH) passing through the uppermost point of the glenoid fossa; L2: line 2, constructed along the posterior slope of articular eminence, connecting the lowermost and most posterior point of the articular eminence and the uppermost and most anterior point of the glenoid fossa on the temporal bone; AEI: Articular Eminence Inclination, the angle measured between the two lines.
