Flow Diagram Landmark-derived Method. Using AVIZO software, sagittal, axial and coronal multiplanar slices, as well as the 3D image reconstructions, were used to determine the position of the seven landmarks used to superimpose the T1 and T2 images; left and right auditory external meatus, left and right foramen spinosum, left and right foramen ovale and dorsum foramen magnum; as well as the ten landmarks use to assess reliability and measurement error. Once data was optimized in Matlab, linear distances between the 3D coordinates were calculated using the Euclidean distance formula in Excel
