- A long narrow well defined opacity running inferiorly from the styloid process anteriorly to just below the lower border of the left angle of the mandible. This is most likely a calcified stylo-hyoid ligament. There is a small lucent line crossing the superior portion of the opacity which is where the ligament flexes. The lower portion of the opacity does not extend all the way to the hyoid bone.
- A large well defined rectangular opacity just below the left angle of the mandible. This is probably a submandibular gland sialolith just below the posterior border of the mylohyoid muscle where the gland duct curves around the muscle.
- A small round well defined uniformly dense opacity just inferior to the long horn of the hyoid bone. This is at the level of C4 and close to the carotid artery bifurcation. The opacity is a good example of a Triticeous cartilage and should not be confused with calcification of the carotid artery which is irregular in shape and density.
