Cleft lip (cheiloschisis) and cleft palate (palatoschisis) which can also occur together as cleft lip and palate are variations of a type of clefting congenital deformity caused by abnormal facial development during gestation. A cleft is a fissure or opening—a gap. It is the non-fusion of the body’s natural structures that form before birth. Approximately 1 in 700 children born have a cleft lip or a cleft palate or both.
