Cleft Lip / Cleft Palate
Cleft lip and cleft palate are birth abnormalities of the mouth and lip. In the Untied States, nearly 6,800 babies are born with oral-facial clefts annually. These abnormalities occur less frequently among African-Americans. Cleft lip and cleft palate occur early in pregnancy when the sides of the lip and the roof of the mouth do not fuse together as they should. A child can have cleft lip, cleft palate, or both. Cleft lip and cleft palate together are more common in boys. It is also important to know that most babies born with a cleft are otherwise healthy with no other birth abnormalities.
- cleft palate
Cleft palate occurs when the roof of the mouth does not completely close, leaving an opening that can extend into the nasal cavity. The cleft may involve either side of the palate. It can extend from the front of the mouth (hard palate) to the throat (soft palate). Often the cleft will also include the lip. Cleft palate is not as noticeable as cleft lip because it is inside the mouth. It may be the only abnormality in the child, or it may be associated with cleft lip or other syndromes. In many cases, other family members have also had a cleft palate at birth.
- cleft lip
Cleft lip is an abnormality in which the lip does not completely form during fetal development. The degree of the cleft lip can vary greatly, from mild (notching of the lip) to severe (large opening from the lip up through the nose). As a parent, it may be stressful to adjust to the obvious abnormality of the face, as it can be very noticeable.
There are different names given to the cleft lip according to its location and how much of the lip is involved. A cleft on one side of the lip that does not extend into the nose is called unilateral incomplete. A cleft on one side of the lip that extends into the nose is called unilateral complete. A cleft that involves both sides of the lip and extends into and involves the nose is called bilateral complete.

Cleft lip and cleft palate may occur together in an infant, or separately. The degree of the abnormality of both cleft lip and cleft palate can vary greatly. The most common early problem associated with these abnormalities is feeding your baby.
The exact cause of cleft lip and cleft palate is not completely understood. Cleft lip and/or cleft palate are caused by multiple genes inherited from both parents, as well as environmental factors that scientists do not yet fully understand. When a combination of genes and environmental factors cause a condition, the inheritance is called "multifactorial" (many factors contribute to the cause). Because genes are involved, the chance for a cleft lip and/or cleft palate to happen again in a family is increased, depending on how many people in the family have a cleft lip and/or cleft palate. If parents without clefts have a baby with a cleft, the chance for them to have another baby with a cleft ranges from 2 to 8 percent. If a parent has a cleft, but no children have a cleft, the chance to have a baby with a cleft is 4 to 6 percent. If a parent and a child have a cleft, the chance is even greater for a future child to be born with a cleft. Genetic consultation is suggested.
The symptoms of these abnormalities are visible during the first examination by your infant's physician. Although the degree of the abnormality can vary, upon inspection of the mouth and lips, the abnormality can be noted, as there is an incomplete closure of either the lip, roof of the mouth, or both.
Beyond the cosmetic abnormality, there are other possible complications that may be associated with cleft lip and cleft palate, including the following:
- feeding difficulties
Feeding difficulties occur more with cleft palate abnormalities. The infant may be unable to suck properly because the roof of the mouth is not formed completely.
- ear infections and hearing loss
Ear infections are often due to a dysfunction of the tube that connects the middle ear and the throat. Recurrent infections can then lead to hearing loss.
- speech and language delay
Due to the opening of the roof of the mouth and the lip, muscle function may be decreased, which can lead to a delay in speech or abnormal speech. Referral to a speech therapist should be discussed with your child's physician.
- dental problems
As a result of the abnormalities, teeth may not erupt normally and orthodontic treatment is usually required.
The most immediate concern for a baby with cleft palate is good nutrition. Sucking for children with a cleft palate is difficult because of the poorly formed roof of the mouth. Children with just a cleft lip (without a cleft palate) do not routinely have feeding difficulties. The following are suggestions to help aid in the feeding of your infant:
- Breastfeeding is allowed. It will take extra time and patience. Be open for alternatives if this is not providing adequate nutrition for your infant. You may still pump your breast and feed your infant breast milk through other techniques.
- Hold your infant in an upright position to help keep the food from coming out of the nose.
- Other feeding devices may be utilized. Consult with your child's physician for more information.
- Small, frequent feedings are recommended. This can be a frustrating and slow process; however, your infant will receive more calories, and therefore, gain weight.
- There are many types of bottles and nipples on the market that can assist with feeding an infant with cleft palate. Consult with your child's physician regarding which type is most appropriate for your child. The following are a few examples:
- NUK nipple
This nipple can be placed on regular bottles or on bottles with disposable bags. The hole can be made larger by making a criss-cross cut in the middle.
- Mead Johnson Nurser®
This is a soft, plastic bottle that is easy to squeeze and has a large crosscut nipple. You may use any nipple that the infant prefers with this system.
- Haberman Feeder®
This is a specially designed bottle system with a valve to help control the air the baby drinks and to prevent milk from going back into the bottle.
These may be used in hospitals following cleft surgery and may also be used at home. Typically, a soft, rubber tube is attached on the end of the syringe, which is then placed in the infant's mouth.
In some cases, supplements may be added to breast milk or formula to help your infant meet his/her calorie needs. Consult your child's physician regarding other home devices (i.e., small paper cups) for feeding your child with a cleft palate.
There may be many people involved in management of a cleft abnormality for your child, because the skills of many different areas are needed to help with the problems that can occur with cleft abnormalities. The following are some of the members of the team:
- plastic/craniofacial surgeon - a surgeon with specialized training in the diagnosis and treatment of skeletal abnormalities of the skull, facial bones, and soft tissue; will work closely with the orthodontists and other specialists to coordinate a surgical plan.
- pediatrician - a physician who will follow the child as he/she grows and help coordinate the multiple specialists involved.
- orthodontist - a dentist who evaluates the position and alignment of your child's teeth and coordinates a treatment plan with the surgeon and other specialists.
- pediatric dentist - a dentist who evaluates and cares for your child's teeth.
- speech and language specialist - a professional who will perform a comprehensive speech evaluation to assess communicative abilities and who will closely monitor your child throughout all developmental stages.
- otolaryngologist (ear-nose-throat specialist) - a physician who will assist in the evaluation and management of ear infections and hearing loss that may be side effects of your child's cleft abnormality.
- audiologist (hearing specialist) - a professional who will assist in the evaluation and management of hearing difficulties your child may have.
- genetic counselor - a professional who reviews the medical and family history, as well as examines your child to help in diagnosis. A genetic counselor also counsels your family regarding risk for recurrence in future pregnancies.
- nurse team coordinator - a registered nurse who combines experience in pediatric nursing with specialization in the care of your child and acts as liaison between your family and the cleft team.
- social worker - a professional who provides guidance and counseling for your child and your family in dealing with the social and emotional aspects of a cleft abnormality and assists your family with community resources and referrals (i.e., support groups).
Treatment for these abnormalities includes surgery and a complete team approach to help with the multiple complications that can occur. Specific treatment will be determined by your child's physician based on:
- your child's age, overall health, and medical history
- specific qualities of your child's abnormality
- your child's tolerance for specific medications, procedures, or therapies
- involvement of other body parts or systems
- your opinion or preference
For most infants with cleft lip alone, the abnormality can be repaired within the first several months of life (usually when the baby is 10 to 12 pounds). This will be decided by your child's surgeon. The goal of this surgery is to fix the separation of the lip. Sometimes, a second operation is needed.
Cleft palate repairs are usually done between the ages of 6 to 18 months. This is a more complicated surgery and is done when the baby is bigger and better able to tolerate the surgery. The exact timing of the surgery will be decided by your child's physician. The goal of this surgery is to fix the roof of the mouth so that your child can eat and learn to talk normally. Sometimes, a second operation is needed.
