Cleft
lip and cleft palate
Overview
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 do not 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 lip or palate can be upsetting, but these conditions can be corrected. In
most babies, a series of surgeries can restore normal function and achieve a
more normal appearance with minimal scarring.
Symptoms
Usually, a split (cleft) in
the lip or palate is immediately identifiable at birth. Cleft lip and cleft
palate may appear as:
A split in the lip and roof
of the mouth (palate) that affects one or both sides of the face
A split in the lip that
appears as only a small notch in the lip or extends from the lip through the
upper gum and palate into the bottom of the nose
A split in the roof of the
mouth that does not 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
When to see a 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.
Causes
Cleft lip and cleft palate
occur when tissues in the baby's face and mouth do not fuse properly. Normally,
the tissues that make up the lip and palate fuse together in the second and
third months of pregnancy. But in babies with cleft lip and cleft palate, the
fusion never takes place or occurs only part way, leaving an opening (cleft).
Researchers believe that
most cases of cleft lip and cleft palate are caused by an interaction of
genetic and environmental factors. In many babies, a definite cause is not
discovered.
The mother or the father can
pass on genes that cause clefting, either alone or as part of a genetic
syndrome that includes a cleft lip or cleft palate as one of its signs. In some
cases, babies inherit a gene that makes them more likely to develop a cleft,
and then an environmental trigger causes the cleft to occur.
Risk factors
Several factors may increase
the likelihood of a baby developing a cleft lip and cleft palate, including:
Family history.
Parents with a family history of cleft lip or cleft palate face a higher risk
of having a baby with a cleft.
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.
Males are more likely to
have a cleft lip with or without cleft palate. Cleft palate without cleft lip
is more common in females. In the United States, cleft lip and palate are most
common in Native Americans and least common in African Americans.
Complications
Children with cleft lip with
or without cleft palate face a variety of challenges, depending on the type and
severity of the cleft.
Difficulty feeding.
One of the most immediate concerns after birth is feeding. While most babies
with cleft lip can breast-feed, a cleft palate may make sucking difficult.
Ear infections and
hearing loss. Babies with cleft palate are especially at
risk of developing middle ear fluid and hearing loss.
Dental problems. If the
cleft extends through the upper gum, tooth development may be affected.
Speech difficulties.
Because the palate is used in forming sounds, the development of normal speech
can be affected by a cleft palate. Speech may sound too nasal.
Challenges of coping
with a medical condition. Children with clefts may
face social, emotional, and behavioral problems due to differences in
appearance and the stress of intensive medical care.
Prevention
After a baby is born with a
cleft, parents are understandably concerned about the possibility of having
another child with the same condition. While many cases of cleft lip and cleft
palate cannot be prevented, consider these steps to increase your understanding
or lower your risk:
Consider genetic
counseling. If you have a family history of cleft lip
and cleft palate, tell your doctor before you become pregnant. Your doctor may
refer you to a genetic counselor who can help determine your risk of having
children with cleft lip and cleft palate.
Take prenatal vitamins. If
you are planning to get pregnant soon, ask your doctor if you should take
prenatal vitamins.
Do not use tobacco or
alcohol. Use of alcohol or tobacco during pregnancy increases
the risk of having a baby with a birth defect.
