What is cleft lip and palate:
Cleft lip and palate are
birth defects of the mouth and lip, also known as oral-facial clefts. A
normal fetus has a split lip and palate, but early in pregnancy, the sides of
the lip and the roof of the mouth should fuse. Failure of fusion results in
cleft lip and/or cleft palate.
·
About 6,000 to 8,000 kids are born in the
United States with oral-facial clefts every year
·
Cleft defects are more common in boys
·
Cleft defects are more common in Asians and
certain groups of American Indians and are less common in African-Americans
·
Less than 13 percent of patients have other
birth defects
What are the different types of
cleft lip and palate?
Unilateral defects –
the most common type of cleft, affecting one side of the lip, with or without a
cleft palate
·
Incomplete unilateral cleft lip – a
notching of the lip that does not extend into the nose
·
Incomplete unilateral cleft lip and palate
– a notching of the lip that does not extend into the nose, accompanied by a
cleft palate
·
Complete unilateral cleft lip and palate
– an opening that extends from one side of the lip into the nose and palate.
Bilateral defects –
affecting both sides of the lip and/or palate, forming two clefts
·
Incomplete bilateral cleft lip and palate – a
notching of both sides of the lip that does not extend into the nose
·
Complete bilateral cleft lip and palate –
an opening that extends from both sides of the lip into both nostrils.
Children
can also have less noticeable form of cleft lip than those depicted above,
known as a form-fruste cleft lip. A form-fruste cleft lip is a small, subtle
indentation of the lip.
Causes:
The cause of cleft lip and palate is not completely understood, though
we know that a combination of genetic and environmental factors contribute to
cleft lip and palate. If parents without clefts have a baby with a cleft, the
chance they will have another baby with a cleft ranges from 2 percent to 8
percent, which suggests a genetic factor. If clefts run in your family, genetic
consultation is recommended.
In addition, there are several syndromes commonly associated
with cleft lip and palate:
·
Van der Woude syndrome
·
Stickler syndrome
·
Pierre Robin sequence or syndrome
·
Hemifacial microsomia
·
Goldenhar syndrome
·
Downs syndrome
·
CHARGE syndrome
·
22q and velocardiofacial syndrome
·
DiGeorge syndrome
·
Oro-mandibular limb hypoplasia syndrome
·
Opitz syndrome
Treatment:
At The
Children’s Hospital of Philadelphia, children with cleft lip and cleft palate
receive coordinated care through our Cleft Lip and Palate Program. The
multidisciplinary program brings together plastic surgeons, pediatricians,
orthodontists and other specialists in order to provide the most comprehensive
care for your child.
The surgical
procedures required for each patient with cleft lip and palate will vary
depending upon the type and severity of the deformity. Timing and treatment
will be adjusted based on each patient’s overall medical needs, but treatment
typically includes a combination of the following procedures and stages,
performed within general time frames based on development.
·
Nasoalveolar molding (NAM) (1 week to 3 months of
age, if needed)
·
Cleft
lip repair (3 to 6 months)
·
Cleft palate repair (9 to 18 months)
·
Palatal expansion (5 to 7 years, if needed)
·
Alveolar bone graft and fistula repair (6 to 9
years)
·
Tip rhinoplasty (6 to 9 years)
·
Phase I orthodontics (6 to 9 years)
·
Phase II orthodontics (14 to 18 years)
·
Orthognathic surgery (jaw surgery) (14 to 18
years)
·
Final touchup surgery (adolescence or adulthood)
