During early pregnancy, separate areas of the face develop individually and then join together. This including the left and right sides of the roof of the mouth and lips. However, if some parts do not join properly, sections don’t meet and the result is a cleft. If the separation 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 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 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, soft tissue and muscle. It 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. 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.
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. This condition is called Pierre Robin syndrome.Since the lip and palate develop separately, it is possible for a child to be born with a cleft lip, palate or both. Cleft defects occur in about one out of every 800 babies.
