Aim: This cross-sectional study was conducted with the object of making a cephalometric evaluation of the cranial base anatomy correlation with the facial pattern and apical bases. Methods: 88 lateral teleradiographies of young white Brazilian with mean age of 10.3 years were used. The Ricketts VERT index was used to determine the facial pattern, and the sample was distributed as follows: 37 in group M (mesofacial), 34 in group D (dolicofacial) and 17 in group B (brachyfacial). The anatomic drawing, demarcation of points, line and plane tracings, and linear and angular measurement gauging were done manually. The cranial base measurements used were S-N, N.S.Ba and S-N.Po-Or and the apical base measurements were S.N.A, S.N.B and A.N.B. Results and Conclusion: It was concluded that, in the correlation between the cranial base and the facial pattern, there was significance between the variable N.S.Ba and the VERT Index. In the correlation between the cranial base and the apical bases, there was significance between N.S.Ba and the variables S.N.A and S.N.B, and between S-N.Po-Or and the variables S.N.A and S.N.B.

Keywords: Facial pattern. Cranial base. Cephalometry.
