Abstract
Sixty-three cephalometric posterior-anterior radiographs were traced and seven bilateral and four single landmarks delineated. The reference points were joined to form triangles representing the component areas of the face. The areas of the triangles were compared with the equivalents on the contra-lateral side. The findings suggest an overall asymmetry with the larger side being the left. The cranial base and maxillary regions tended to be larger on the left, the mandibular and the dento-alveolar regions exhibiting a greater degree of symmetry.
