Oral-facial clefts are birth defects in which the tissues of the mouth or lip don't form properly during foetal development. About 1 in 800 children born in Australia will have an oral-facial cleft. The majority of children born with an oral-facial cleft have no other birth defects.
Both cleft lip and cleft palate are treatable. Most children born with either or both of these conditions can have reconstructive surgery while they're still infants to correct the defect and significantly improve their facial appearance.
