An unusual case of median cleft lip with orbital hypotelorism--a missing link in the classification

De Myer (1963) classified median-facial anomalies into two groups: 1. Median cleft lip with orbital hypotelorism 2. Median cleft lip with orbital hypertelorism. The first group is characterised by median-cleft lip, absence of premaxilla, nasal skeleton, and crista galli. In addition, there is a holoprosencephaly which may involve the whole forebrain or a smaller part of the brain. In this group, the children die within the first year or during childhood and always suffer from mental retardation. In this report, we present a 12-year-old child with an unusual form of median cleft lip with hypotelorism without brain deformity.
