This study was designed to explore the significance of the spheno-occipital synchondrosis in cranial base and craniofacial development.
Premature fusion of the spheno-occipital synchondrosis in the guinea pig was induced by placing a wire staple in the cranial base across the synchondrosis. One end of the staple was placed in the basi-occipital bone and the other end in the basi-sphenoid bone.
Results of this early closure showed marked changes in craniofacial morphology. The entire cranium anterior to the auditory bullae dropped down in relation to the axial skeleton. The cranial base from basion to the intersphenoidal synchondrosis was markedly shortened. The anterior end of the occlusal plane appeared to rotate in an upward direction. Premature closure of the spheno-occipital synchondrosis did decidedly affect the growth pattern of the craniofacial complex.
