Lateral Cephalometric Skull Anatomy – Part I 1


I had a request a couple months ago wanting more anatomy on lateral cephalometric skull radiographs specifically those landmarks used in orthodontics. As I am not an orthodontist and do not make tracings of lateral cephalometric skull I will not be going over how to trace but where the anatomical landmarks are along with radiographic examples.

Nasion – the suture between the frontal bone and nasal bones (black dotted line and orange arrow).

Rhinion – tip of the nasal bone (white arrow).

Suprarobital – junction of the orbit at the superior aspect where it becomes the roof of the orbital cavity (black arrows).

Roof of the orbital cavity – just like the name implies; the roof of the orbital cavity.

I’m not sure how many parts this will take but it’ll be a few so more coming. If you have any questions or comments, please leave them below. Thanks and enjoy!
