Cleft Lip and Palate Surgery
Cleft lip and cleft palate are facial and oral malformations that occur very early in pregnancy, while the baby is developing inside its mother. A cleft results when there is not enough tissue in the mouth or lip area, and the tissue that is available does not join together properly.
A cleft lip is a physical split or separation of the two sides of the upper lip and appears as a narrow opening or gap in the skin of the upper lip. This separation often extends beyond the base of the nose and includes the bones of the upper jaw and/or upper gum.
A cleft palate is a split or opening in the roof of the mouth. A cleft palate can involve the hard palate (the bony front portion of the roof of the mouth) and/or the soft palate (the soft back portion of the roof of the mouth).
Cleft lip and cleft palate can occur on one or both sides of the mouth. Because the lip and the palate develop separately, it is possible to have a cleft lip without a cleft palate, a cleft palate without a cleft lip, or both a cleft lip and cleft palate together.
Who gets cleft lip and/or 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.
What causes a cleft lip and cleft palate?
In most cases, the cause of cleft lip and cleft palate is not known and 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 antiseizure/anticonvulsant medications, acne treatment medications containing Accutane, or methotrexate, a drug commonly used for treating cancer, arthritis, and psoriasis, may cause cleft lip and/or cleft palate.
The condition may also occur as a result of exposure to viruses or chemicals while the baby is in the womb. In other situations, cleft lip and cleft palate may be part of another medical condition, such as Pierre Robin Malformation Sequence, Amniotic Banding (also called Constriction Band Syndrome), Hemifacial Microsomia/Goldenhar Syndrome, or Tessier Facial Clefts, among others.
How are cleft lip and/or cleft palate diagnosed?
Because clefting causes very obvious physical changes, it's 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 before the baby's birth, a physical examination 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.
What problems are associated with cleft lip and/or cleft palate?
- Eating problems: With a separation or opening in the palate, food and liquids can pass from the mouth back through the nose. Fortunately, specially designed baby bottles and nipples that help keep fluids flowing downward toward the stomach are available. Children with a cleft palate may need to wear a man-made palate to help them eat properly and ensure that they are receiving adequate nutrition until surgical treatment is provided.
- Ear infections and hearing loss: Children with cleft palate are at increased risk of ear infections since they are more prone to fluid buildup in the middle ear. If left untreated, ear infections can cause hearing loss. To prevent this from happening, children with cleft palate usually need special tubes placed in the eardrums to aid fluid drainage, and their hearing needs to be checked once a year.
- Speech problems: Children with cleft lip or cleft palate may also have trouble speaking. These children’s voices don’t carry well, the voice may take on a nasal sound, and the speech may be difficult to understand. Not all children have these problems, and surgery may fix these problems entirely for some. For others, a special doctor called a speech pathologist will work with the child to resolve speech difficulties.
- Dental problems: Children with clefts are more prone to a larger than average number of cavities and often have missing, extra, malformed, or displaced teeth requiring dental and orthodontic treatments. In addition, children with cleft palate often have an alveolar ridge defect. The alveolus is the bony upper gum that contains teeth. A defect in the alveolus can (1) displace, tip, or rotate permanent teeth, (2) prevent permanent teeth from appearing, and (3) prevent the alveolar ridge from forming. These problems can be fixed through oral surgery. 4. Can cause premature loss of erupting canines, and incisors.
Who treats children with cleft lip and/or palate?
Because of the number of oral health and medical problems associated with a cleft lip or cleft palate, a team of doctors and other specialists is usually involved in the care of these children. Members of a cleft lip and palate team typically include:
- Plastic surgeon to evaluate and perform necessary surgeries on the lip and/or palate
- Otolaryngologist (an ear, nose, and throat doctor) to evaluate hearing problems and consider treatment options for hearing problems
- Oral surgeon to reposition segments of the upper jaw when needed, to improve function and appearance, and to repair the cleft of the gum
- Orthodontist to straighten and reposition teeth
- Dentist to perform routine dental care
- Prosthodontist to make artificial teeth and dental appliances to improve the appearance and to meet functional requirements for eating and speaking
- Speech pathologist to assess speech and feeding problems
- Speech therapist to work with child to improve speech
- Audiologist (a specialist in communication disorders involving a hearing impairment) to assess and monitor hearing
- Nurse coordinator to provide ongoing supervision of the child’s health
- Social worker/psychologist to support the family and assess any adjustment problems
- Geneticist to help parents and adult patients understand the chances of having more children with these conditions
These health care team members work together to develop a plan of care to meet the individual needs of each patient. Treatment usually begins in infancy and often continues through early adulthood.
How are cleft lip and 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 3 and 6 months old to close the lip. The second surgery is usually from 9-12 months old and 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.
What is the outlook for children with cleft lip and/or palate?
Although treatment may extend over several years and require several surgeries depending upon the involvement, most children affected by this condition can achieve normal appearance, speech, and eating.
How should dental care needs of children with cleft lips or palates be met?
Generally, the preventive and restorative dental care needs of children with clefts are the same as for other children. However, children with cleft lip and/or palate may have special problems related to missing, malformed, or malpositioned teeth that require close monitoring.
- Early dental care. Like other children, children born with cleft lip and/or 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 is 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 3 years 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, orthodontics 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.
