Classification, etiology, and genetic aspects of craniofacial anomalies
Abstract:
The shape and function of the cranium and face at birth are the end-products of complex and poorly understood developmental processes. In this article I will attempt first to review normal craniofacial development, believing that this basic information is essential to the understanding of abnormal development. I will then review a scheme of classification of anomalies based on etiologic considerations, illustrating each etiologic factor with conditions encountered in practice. Genetic principles in the etiology of craniofacial anomalies will be emphasized. Because of space constraints, no attempt will be made to catalogue syndromes of craniofacial anomalies. The reader is referred to standard reference texts for such comprehensive listings.

Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
