Neck Space Anatomy

Abstract

Neck anatomy is often described as complex and difficult to understand. While it is true that there are many structures contained within it, separating these into compartments defined by layers of deep cervical fascia makes it far simpler to understand, not only the anatomy, but also pathology arising within them. The concept of dividing the neck into naso-, oro-, and hypopharynx suggests discrete regions, separated from one another. In reality, there are no horizontal boundaries preventing disease spreading from one to another. Rather, anatomical structures are organized by fascial layers into craniocaudal ‘tubes’ along which infection, etc. can spread. By understanding this concept, one can predict disease patterns and correctly image the patient. This chapter aims to provide the reader with simple concepts on which to build their knowledge. It is not a comprehensive list of every muscle and nerve in the head and neck. There are plenty of excellent books that do this. It is easy to read and understand with lots of pictures (as I know how much Radiologists love images!). Enjoy….
