title: Perspectives on craniofacial asymmetry. I. The biology of asymmetry.
abstract: Part I introduces the survey and presents a topic outline of the six parts that make up this series of articles on craniofacial asymmetry. The discussion in Part I considers normal variation, normal and abnormal laterality, types of anomalies that may be asymmetric, and finally, some well-known causes of craniofacial asymmetry.
