^*The angles were measured at the anterolateral intersection of each line with the coronal plane. (See Figure 1).

Abbreviations:

AMF = anteromedial foramen

AMI = anteromedial trigeminal impression

PLF = posterolateral foramen

PLI = posterolateral trigeminal impression

Centroid = centroid of the foramen
