<unk>  (from Greek kebos, "monkey" + kephale, "head") is a developmental anomaly that is part of a group of defects called holoprosencephaly.<unk>  involves the presence of two separate eyes set close together and a small, flat nose with a single nostril (no nasal septum). It may be diagnosed before or after birth. It has a very poor prognosis, with most affected infants dying soon after birth. It is very rare, having been estimated to affect around 1 in 40,000 deliveries.
