What are cleft lip and cleft palate?
Cleft lip and cleft palate are openings or splits in the upper lip, the roof of the mouth (palate) or both. Cleft lip and cleft palate result when facial structures that are developing in an unborn baby don’t close completely.
Cleft lip and cleft palate are among the most common birth defects. They most commonly occur as isolated birth defects but are also associated with many inherited genetic conditions or syndromes.
Having a baby born with a cleft can be upsetting, but cleft lip and cleft palate can be corrected. In most babies, a series of surgeries can restore normal function and achieve a more normal appearance with minimal scarring.
How common is cleft lip and cleft palate?
Cleft lip, with or without cleft palate, affects one in 700 babies annually, and is the fourth most common birth defect in the U.S. Clefts occur more often in children of Asian, Latino, or Native American descent. Compared with girls, twice as many boys have a cleft lip, both with and without a cleft palate. However, compared with boys, twice as many girls have cleft palate without a cleft lip. Please discuss with your doctor for further information.
What are the symptoms of cleft lip and cleft palate?
The common symptoms of cleft lip and cleft palate are:
- A split in the lip and roof of the mouth (palate) that can affect one or both sides of the face
- A split in the lip that can appear as only a small notch in the lip or can extend from the lip through the upper gum and palate into the bottom of the nose
- A split in the roof of the mouth that doesn’t affect the appearance of the face
Less commonly, a cleft occurs only in the muscles of the soft palate (submucous cleft palate), which are at the back of the mouth and covered by the mouth’s lining. This type of cleft often goes unnoticed at birth and may not be diagnosed until later when signs develop. Signs and symptoms of submucous cleft palate may include:
- Difficulty with feedings
- Difficulty swallowing, with potential for liquids or foods to come out the nose
- Nasal speaking voice
- Chronic ear infections
There may be some symptoms not listed above. If you have any concerns about a symptom, please consult your doctor.
When should I see my doctor?
A cleft lip and cleft palate are usually noticed at birth, and your doctor may start coordinating care at that time. If your baby has signs and symptoms of a submucous cleft palate, make an appointment with your child’s doctor.
What causes cleft lip and cleft palate?
In most cases, the cause of cleft lip and cleft palate is unknown. These conditions cannot be prevented. Most scientists believe clefts are due to a combination of genetic and environmental factors. There appears to be a greater chance of clefting in a newborn if a sibling, parent, or relative has had the problem.
Another potential cause may be related to a medication a mother may have taken during her pregnancy. Some drugs may cause cleft lip and cleft palate. Among them: anti-seizure/anticonvulsant drugs, acne drugs containing Accutane, and methotrexate, a drug commonly used for treating cancer, arthritis, and psoriasis.
Cleft lip and cleft palate may also occur as a result of exposure to viruses or chemicals while the fetus is developing in the womb.
In other situations, cleft lip and cleft palate may be part of another medical condition.
What increases my risk for cleft lip and cleft palate?
There are many risk factors for cleft lip and cleft palate, such as:
- Family history. Parents with a family history of cleft lip or cleft palate face a higher risk of having a baby with a cleft.
- In the United States, cleft lip and palate are reportedly most common in Native Americans and least common in African-Americans.
- Males are twice as likely to have a cleft lip with or without cleft palate. Cleft palate without cleft lip is more common in females.
- Exposure to certain substances during pregnancy. Cleft lip and cleft palate may be more likely to occur in pregnant women who smoke cigarettes, drink alcohol or take certain medications.
- Having diabetes. There is some evidence that women diagnosed with diabetes before pregnancy may have an increased risk of having a baby with a cleft lip with or without a cleft palate.
- Being obese during pregnancy. There is some evidence that babies born to obese women may have increased risk of cleft lip and palate.
Diagnosis & treatment

How are cleft lip and cleft palate diagnosed?
Because clefting causes very obvious physical changes, a cleft lip or cleft palate is easy to diagnose. Prenatal ultrasound can sometimes determine if a cleft exists in an unborn child. If the clefting has not been detected in an ultrasound prior to the baby’s birth, a physical exam of the mouth, nose, and palate confirms the presence of cleft lip or cleft palate after a child’s birth. Sometimes diagnostic testing may be conducted to determine or rule out the presence of other abnormalities.
How are cleft lip and cleft palate treated?
A cleft lip may require one or two surgeries depending on the extent of the repair needed. The initial surgery is usually performed by the time a baby is 3 months old.
Repair of a cleft palate often requires multiple surgeries over the course of 18 years. The first surgery to repair the palate usually occurs when the baby is between 6 and 12 months old. The initial surgery creates a functional palate, reduces the chances that fluid will develop in the middle ears, and aids in the proper development of the teeth and facial bones.
Children with a cleft palate may also need a bone graft when they are about 8 years old to fill in the upper gum line so that it can support permanent teeth and stabilize the upper jaw. About 20% of children with a cleft palate require further surgeries to help improve their speech.
Once the permanent teeth grow in, braces are often needed to straighten the teeth.
Additional surgeries may be performed to improve the appearance of the lip and nose, close openings between the mouth and nose, help breathing, and stabilize and realign the jaw. Final repairs of the scars left by the initial surgery will probably not be performed until adolescence, when the facial structure is more fully developed.
Lifestyle changes & home remedies
What are some lifestyle changes or home remedies that can help me manage cleft lip and cleft palate?
The following lifestyles and home remedies might help you cope with cleft lip and cleft palate:
- Early dental care. Like other children, children born with cleft lip and cleft palate require proper cleaning, good nutrition, and fluoride treatment in order to have healthy teeth. Appropriate cleaning with a small, soft-bristled toothbrush should begin as soon as teeth erupt. If a soft children’s toothbrush will not adequately clean the teeth because of the modified shape of the mouth and teeth, a toothette may be recommended by your dentist. A toothette is a soft, mouthwash-containing sponge on a handle that’s used to swab teeth. Many dentists recommend that the first dental visit be scheduled at about 1 year of age or even earlier if there are special dental problems. Routine dental care can begin around 1 year of age.
- Orthodontic care. A first orthodontic appointment may be scheduled before the child has any teeth. The purpose of this appointment is to assess facial growth, especially jaw development. After teeth erupt, an orthodontist can further assess a child’s short and long-term dental needs. After the permanent teeth erupt, orthodontic treatment can be applied to align the teeth.
- Prosthodontic care. A prosthodontist is a member of the cleft palate team. He or she may make a dental bridge to replace missing teeth or make special appliances called “speech bulbs” or “palatal lifts” to help close the nose from the mouth so that speech sounds more normal. The prosthodontist coordinates treatment with the oral or plastic surgeon and with the speech pathologist.
If you have any questions, please consult with your doctor to better understand the best solution for you.
