Cleft lip and palate are birth defects that affect the upper lip and the roof of the mouth.

There are many causes for of cleft lip and palate. Problems with genes passed down from one or both parents, drugs, viruses, or other toxins can all cause such birth defects. Cleft lip and palate may occur along with other syndromes or birth defects.

A cleft lip and palate can affect the appearance of one's face, and may lead to problems with feeding and speech, as well as ear infections. Problems may range from a small notch in the lip to a complete groove that runs into the roof of the mouth and nose. These features may occur separately or together.

Risk factors include a family history of cleft lip or palate and other birth defect. About 1 out of 2,500 people have a cleft palate.

A physical examination of the mouth, nose, and palate confirms a cleft lip or cleft palate. Medical tests may be done to rule out other possible health conditions.

Surgery to close the cleft lip is usually done at 3 - 9 months of age. Surgery may be needed later in life the problem severely affects the nose area.

A cleft palate is usually closed within the first year of life so that the child's speech normally develops. Sometimes a prosthetic device is temporarily used to close the palate so the baby can feed and grow until surgery can be done.

Continued follow-up may be needed with speech therapists and orthodontists.
