Change in facial shape in micro-, macro- and normocephalics

In view of the dubious scientific validity of traditional cephalometric analyses, the more accurate technique of biorthogonal analysis was used in this study. Developed from D'Arcy Thompson's transformation grids, this technique showed similar craniofacial shape changes in micro-, macro- and normocephalics between the ages of 12 and 16 years, implying the contrasts in facial form between these 3 samples predominantly reflect size rather than shape differences.
