Otocephaly is a rare malformation characterized by the association of agnathia (agenesis of mandible) or mandibular hypoplasia, melotia (anteromedial malposition of ears), microstomia (small mouth), aglossia or microglossia (absent or rudimentary tongue). This rare anomaly of the ventral portion of first brachial arch is a consequence of failure of migration of neural crest cells from hind brain. It leads to the development of maxillary and mandibular prominences and starts to develop at the fourth and fifth week of gestation. We hereby present the autopsy findings of a fetus of 28 weeks gestation abortus having otocephaly without holoprosencephaly.
