Imaging Anatomy of the Oral Cavity... made Easy

This video is about the imaging anatomy of the oral cavity. Head and neck imaging can feel overwhelming at times, there’s a lot of anatomy packed into a very small space, with structures lying very close to each other, but with a systematic approach, it becomes much easier than it seems. In the end, a good knowledge of anatomy is critical for localizing pathology and for determining whether a lesion arises in the oral cavity or the oropharynx. By the end of this video, you’ll have a clear overview of the essential anatomy and its relevance in clinical practice!
