Abstract

This chapter discusses the normal anatomy of the maxillofacial region and variations thereof when present and clinically relevant. Single or rare cases of an anatomical variation are excluded, as are very minor variations, such as deviations in the course of a nerve in the range of millimeters. Gross anatomy and histology of the most relevant structures in the maxillofacial region are described by anatomical region.
