RESUMO
Most publications on maxillofacial malformation are based on their topography and terminology. The list of authors is endless in most cases there are only minor variants. Thus, we are attempting to establish the embryoclinical correlation of maxillofacial malformations produced by changes in the structures of the cephalic pole of the embryo. For such systematization we have considered the following items: 1. Changes in the frontal structure. 2. Changes in upper maxillary structures. 3. Changes in the lower maxillary or mandibular structures. 4. Pathologic associations. In each of these buttons, the structures produced or correlated with them are subsequently analyzed, the same as basic changes and clinical syndromes produced by them and resulting in an embryoclinical systematization.
