The exact cause is unknown. Cleft lips and cleft palates are congenital defects that occur early in embryonic development. Scientists believe a combination of genetic and environmental factors, such as maternal illness, drugs or malnutrition, may lead to a cleft lip or cleft palate. If one child in a family is born with a cleft, the risk increases by 2 to 4 percent that future children in the family will suffer from the same defect.
Scientists are researching methods to prevent cleft lips and palates. One finding, according to research studies, is that mothers who take multivitamins containing folic acid before conception and during the first two months of pregnancy may reduce their risk of giving birth to a baby with a cleft.
Yes. Cleft lip and palate surgery provides excellent results. A pediatrician and a plastic surgeon work with a child's parents to choose the best timing for surgery. Most surgeons agree that a cleft lip should be repaired by the time a baby is 3 months old. To repair the partition of mouth and nose as early as possible, a cleft palate generally is repaired between the ages of 12 and 18 months. Any surgical procedure is dependent upon a child's general health and the nature of the cleft lip or cleft palate.
Cleft lips and cleft palates occur in approximately 1 per 500-700 births, the ratio varying considerably across geographic areas or ethnic groupings. (Source: World Health Organization International Collaborative Research on Craniofacial Anomalies)
