Figure 3: The unilateral sagittal images above, from two different subjects, were selected as examples of the most common canal pathways in the anterior-posterior plane. Most common sagittal canal pathways as demonstrated in the images are (a) canal travels anterior-inferior and (b) canal travels directly inferior for a distance then anterior-inferior for the remainder.
