ABSTRACT
Assessment of soft tissue profile is an essential step in planning the correction of maxillofacial deformities. In this study 50 lateral cepholograms of young adult Egyptians with normal occlusion were analyzed to get the nor mal soft tissue measurements of anteroposterior relation and vertical proportions. This study has proved the presence of some difference in the anteroposterior relations and vertical proportions between the Egyptians and American Caucasians. Egyptians have a soft tissue chin that is less prominent than the Americans, but the soft tissue chin thickness is larger in Egyptians than the Americans. Upper and lower lips are more protrusive in Egyptians than the Americans. Both upper and lower lips at vermilion are thicker in Egyptians than the Americans. In the vertical proportions, Ricketts-Devine proportions could be applied in the Egyptians faces with one difference The subnasal point [Sn.] should be used in Egyptians instead of the Alar rim point [Ar.] that was used by Ricketts in Americans
