Cleft Palate/Lip

When a human fetus is developing, different areas of the face form separately and later join together. These separate pieces include the left and right sides of the roof of the mouth and lips. When some parts do not join properly, those sections don’t meet and the result is a cleft. If the cleft occurs in the upper lip, the child is said to have a cleft lip.

A completely formed lip is important not only for a normal facial appearance but also for sucking (critical for nourishment of newborns) and to form certain sounds made during speech. A cleft lip is a condition that creates an opening in the upper lip between the mouth and nose. It looks as though there is a split in the lip. It can range from a slight notch in the colored portion of the lip to complete separation in one or both sides of the lip extending up and into the nose. A cleft on one side is called a unilateral cleft. If a cleft occurs on both sides, it is called a bilateral cleft.

A cleft in the gum may occur in association with a cleft lip. This may range from a small notch in the gum to a complete division of the gum into separate parts. A similar defect in the roof of the mouth is called a cleft palate.

The palate is the roof of your mouth. It is made of bone and muscle and is covered by a thin, wet skin that forms the red covering inside the mouth. You can feel your own palate by running your tongue over the top of your mouth. Its purpose is to separate your nose from your mouth. The palate has an extremely important role during speech because when you talk, it prevents air from blowing out of your nose instead of your mouth. The palate is also very important when eating. It prevents food and liquids from going up into the nose.

As in cleft lip, a cleft palate occurs in early pregnancy when separate areas of the face have developed individually do not join together properly. A cleft palate occurs when there is an opening in the roof of the mouth. The back of the palate is called the soft palate and the front is known as the hard palate. A cleft palate can range from just an opening at the back of the soft palate to a nearly complete separation of the roof of the mouth (soft and hard palate).


Sometimes a baby with a cleft palate may have a small chin and a few babies with this combination may have difficulties with breathing easily. This condition may be called Pierre Robin sequence.
