anterior cranial fossa

The anteriormost of the three divisions of the internal cranial base, which houses the inferior face of the frontal lobes of the brain. The floor of the fossa is covered by dura mater and is formed by contributions from the frontal, ethmoid and sphenoid bones. The anterior cranial fossa is limited anteriorly and laterally by the frontal bone.

Results demonstrated that anterior cranial base inclination SN-FH significantly increased in the high-angle Angle's class II group compared with the average-angle and low-angle Angle's class II groups.
Similarly, the comparison between the Caucasian and Pakistani females revealed a statistically significant difference (p less than 0.05) in all parameters except the anterior cranial base (S-N) measurements and the posterior facial height measurements (S-GO) which showed no statistically significant difference between the two populations.
As the anterior cranial fossa is the template that establishes the basic dimensions of the maxilla [Enlow, 1983], the deficiency in the maxillary arch can be secondary to the deficiency in the anterior cranial base. It can also be due to the primary effect of the condition on membranous bone ossification.
