Oral Cleft is a group of conditions that includes cleft lip (CL), cleft palate (CP), and both together (CLP). A cleft lip contains an opening in the upper lip that may extend into the nose. The opening may be on one side, both sides, or in the middle. A cleft palate is when the roof of the mouth contains an opening into the nose. These disorders can result in feeding problems, speech problems, hearing problems, and frequent ear infections. Less than half the time the condition is associated with other disorders.

Cleft lip and palate are the result of tissues of the face not joining properly during development.The cause is unknown in most cases.

Cleft lip and cleft palate can often be diagnosed during pregnancy with an ultrasound exam.

A cleft lip or palate can be successfully treated with surgery. This is often done in the first few months of life for cleft lip and before eighteen months for cleft palate.

Cleft lip and palate occurs in about 1 to 2 per 1000 births.
