Which facial features are associated with fetal alcohol syndrome?

Explanation:
Fetal alcohol syndrome causes distinctive craniofacial changes that reflect disrupted fetal development from alcohol exposure, especially in the first trimester. A small head (microcephaly) and flatter midface are among the hallmark facial features, often with a smooth philtrum and a thin upper lip. This combination best matches the known facial phenotype of fetal alcohol exposure. Other descriptions describe features that aren’t typical for FAS, such as an enlarged skull or an elongated face, a prominent nose with large lips, or a normal philtrum, which do not align with the characteristic pattern.
