Lateral Cephalometric Skull Anatomy – Part III


Now onto the temporal region.

Zygomatic Arch (green area) – Made up by the zygomatic bone and zygomatic process of the temporal bone.

Mandibular Notch (blue line) – Notch between the condyle and coronoid process of the mandible.

Posterior margin of the ramus (white line) – Just as the name states – the posterior margin of the ramus.

Mastoid Process (purple circle) – The inferior portion of the temporal bone where the mastoid air cells are found.
