Facial Bones: Radiographic Anatomy - Video Lesson

Hey, everybody. Welcome to today's lesson on radiographic anatomy, demonstrated on routine projections of the facial bones. In a previous lesson, we discussed the anatomy and which radiographic projections are routinely performed. So let's tie that information to the radiographs themselves. As a reminder, the routine radiographic projections of the facial bones are lateral, PA axial, also called Caldwell method, and parietoecanthial, also called Waters method. We will also be reviewing the submental vertical or SMV projection of the zygomatic arches. Take a look at this radio graph. What projection is being demonstrated? How do you know? Let's find out the answers to these questions. If you said this radiograph is a lateral projection of the facial bones, you're correct. Let's look at the evaluation criteria to see how we know for sure. This image is very similar to a lateral skull or lateral sinuses, but with slightly different centering and collimation. In this
