A consideration of the systemic factors that influence frontal sinus pneumatization

Abstract

The authors present the embryology and comparative anatomy of the frontal sinuses pertinent to a discussion of the systemic factors which influence frontal sinus pneumatization. There are at least three important factors involved: 1) craniofacial configuration, 2) thickness of the frontal bone, 3) growth hormones. Various clinical entities which illustrate these points are discussed.
