We report the prenatal ultrasonographic diagnosis of a fetus with mandibulofacial
dysostosis (Treacher Collins syndrome). Sonographic findings included: polyhydramnios,
microcephaly, abnormal fetal facial features (slanting forehead, microphthalmos, micrognathia),
and abnormal fetal swallowing. A review of the current literature pertaining to prenatal
diagnosis of this condition is presented.
