What is a cleft palate?
“Palate” is another name for the roof of your mouth. The palate is both the roof of your mouth and the floor of your nose. The palate has two parts: the front, or hard palate, and the back, or soft palate. The hard palate is made of bone and the soft palate is made of muscle.

A cleft is simply a gap, separation, or hole that results from abnormal fetal development. A cleft palate is a birth defect that results when tissues of the palate fail to fuse during early fetal development. This failure occurs during the 8th and 12th week of gestation. The condition varies from a defect in the muscles of the soft palate only (a submucous cleft palate, Fig. 1) to a complete separation of the skin and bone of both the hard and soft palate (Fig. 2). It is also possible to have a cleft of the soft palate, without a cleft of the hard palate (Fig. 3). But it is not possible to have a cleft of the hard palate without a cleft of the soft palate. Cleft palate surgery is required to repair a cleft palate.
What causes a cleft palate?
It may surprise you to know that despite years of research we still do not have a great understanding of why cleft palates occur. Most doctors and scientists agree that clefts are a combination of genetic as well as environmental factors including drugs, infections, maternal illness, and possibly vitamin deficiencies. Other birth defects can occur in children with cleft palates. Some of these defects are obvious and some are more difficult to detect. However, most children born with a cleft lip and/or palate are otherwise normal, healthy children.How do I feed my child with a cleft palate?
It is extremely difficult to successfully breast feed a child with a cleft palate. This is one of the many reasons that children in developing countries born with cleft palates do not survive past infancy. In order for a child to breast feed (or bottle feed with a conventional nipple), he/she needs to create suction within the mouth. Suction cannot be created when there is an opening, or cleft, in the roof of the mouth. Some well-intentioned friends and/or medical professionals may encourage you to try and breast feed your child anyway. Unfortunately encouraging a mother to breast feed a child with a cleft palate only sets mother and baby up for failure. But rest assured, there are ways to successfully feed a child with a cleft palate. Special nipples are available that allow you to help deliver formula or pumped breast milk from a bottle into your infants mouth. Feeding a baby with a cleft palate takes time and patience. Many resources are available to help you and your family learn the techniques to successfully feed your child. More specific information is available on our cleft lip and palate feeding page. If you are having difficulty successfully feeding your child, please call our office to arrange some assistance.Why is a cleft palate repaired?
If a child can eat and drink with a cleft palate, you may wonder why a cleft palate needs to be repaired at all. The reason is simple—speech. Most human speech and language requires regulation of air flow through the nose and mouth. If air leaks out of the nose while we are speaking, many of the sounds we make do not sound right. When a lot of air leaks out of the nose, our speech becomes almost unintelligible. A child with an unrepaired cleft palate cannot stop air from rushing out the nose during speech (Fig. 4). This makes it very difficult for a child to learn how to speak correctly. It also makes it difficult for others to understand his/her speech.How is a cleft palate repaired?
The repair of a cleft palate requires cleft palate reconstructive surgery and general anesthesia. The cleft is repaired by bringing the tissues around the cleft together. There is no need for artificial materials or bone grafts in order to repair the palate (Fig. 5). (However, it is important to remember that some children with cleft lip and palate have a cleft in the gum line in addition to a cleft in the hard palate. Although the cleft of the hard palate is repaired early in life, the cleft in the gum line is not repaired until your child is much older—usually between 6 and 8 years old. Repair of the gum line does involve a bone graft.)When is the right time for cleft palate surgery?
Are there any instructions I need to follow before cleft palate surgery?
Your child must have a physical examination by his or her pediatrician or family doctor within 7 days before surgery to make sure he or she is in good health. The doctor you see needs to complete the History and Physical form provided by our office. You must bring the completed form with you the day of surgery. Your child should be drinking from a “sippy” cup and eating table foods before cleft palate surgery. Most children begin this transition 1 month before surgery. If you are having trouble weaning your child off the bottle, please let your surgeon know at least 4 weeks before your planned date for surgery. Your surgeon will delay cleft palate surgery if your child still requires any bottle feeding.For your child’s safety, it is very important that he or she have an empty stomach when anesthesia is given. Please follow our preoperative Eating and Drinking Guidelines. If you do not follow these guidelines, your child’s surgery will be cancelled.
