CT Facial Bones (Coronal) - Video Lesson

Hey, everybody. Welcome back. This lesson is about the facial bones as seen in CT imaging. We'll look at the facial bones using the coronal plane. This is a coronal reformation of the facial bones. From the lower left graphic, you can see that we're very near the front of the face, just at the edge of the nasal cavity. Also notice that this image is in a plane that is roughly perpendicular to the hard palate. That's the normal orientation for coronal images through the facial bones. At this point, only a few structures are visible. We can see the nasal bones forming the bridge of the nose. We can also see the perpendicular plate of the ethmoid bone. The perpendicular plate joins to the vomer and forms the bony nasal septum. We can't see the vomer just yet in this scan. Finally, we can see the upper teeth. The upper teeth extend from the alveolar process of the maxillary bones. In the next image, we'll move slightly deeper into the face. We'll start at the top of the image. This
