The Sagittal Growth of the Foetal Cranial Base

There is an increase in the angular relationship between the anterior and posterior cranial components in foetal life. The angular changes taking place seem to occur in the region of the sphenoethmoidal junction.

The Sagittal Growth of the Lower Face During Foetal Life

The mandibular line (ML) seems to show stability with both the anterior cranial base (NSI,) and with the Nasal Line (NL) during foetal lifr. The jaw angle, gn?go?co also shows angular stability during the same period.

The Sagittal Growth of the Upper Face During Foetal Life

The nasal septum seems to be stable in its angular relationship with the anterior cranial base The Nasal Line NL despite an initial small increase seems to follow the same trend as the anterior cranial base and nasal septum in their angular behaviour to the posterior cranial base.
