Facial malformations are embryonic morphological accidents involving the prosencephalic frontonasal process (facial cleft), the branchial arches (laterofacial malformations) or the rhombencephalic process. Knowing the future development of these clusters of cells helps in the search for neurological brain abnormalities associated with facial cleft and the respiratory, cardiac, gastrointestinal and brainstem malformations associated with laterofacial malformations and Pierre Robin syndrome. Taking care of the newborn already in the maternity unit prevents the consequences of vital distress and enables the child to be placed under conditions of normal psychomotor development.
