Cleft Lip and Palate

Oral-Facial Clefts

An oral-facial cleft is a birth defect that occurs when the lip or the roof of the mouth do not form properly. The defect may include a cleft lip, a cleft palate or both.

A cleft lip is a gap in the upper lip, usually just below the nose. A cleft palate is a gap in the roof of the mouth or in the soft tissue at the back of the mouth. In the majority of cases, a cleft lip and cleft palate occur together.

What Causes a Cleft?

Early in pregnancy, all babies have an opening in the lip and palate. As the baby grows, these openings should gradually grow together and close by birth. In children with oral-facial clefts, these openings fail to close. The exact cause is unknown.

Risk Factors

Baby:

  • Having other birth defects
  • Male gender
  • Having a sibling, parent or other close relative born with an oral-facial cleft

Mother:

  • Taking certain drugs during pregnancy
  • Smoking
  • Consuming alcohol
  • Having diabetes

Preventing Oral-Facial Clefts

Pregnant women and women who are likely to become pregnant can do the following to help prevent oral-facial clefts in their unborn children:

  • Consume 400 micrograms of folic acid every day and eat foods containing folic acid, such as:
    • Fruits and orange juice
    • Green, leafy vegetables
    • Dried beans and peas
    • Pasta, rice, bread, flour and cereals
  • Do not smoke or drink alcohol during pregnancy.
  • Talk to your doctor about any medications during pregnancy. 
  • Get early and regular prenatal care.

Diagnosing Clefts

Your doctor may be able to see a cleft lip or palate during an ultrasound examination as early as 18 weeks into pregnancy. Cleft palate may be harder to see before birth because it's inside the mouth.

Your medical team can't start treatment until after birth. However, diagnosis during pregnancy will allow time to prepare a care plan. Rarely, a mild cleft palate may go undiagnosed for several months or even years after birth.

Cleft lip and palate are sometimes associated with other medical conditions. Your doctor can tell you whether or not your child’s cleft is a sign of a larger condition.

Treating a Cleft Lip or Cleft Palate

Surgery is the main treatment. The primary goal of surgery is to close the gap in the lip and palate. Other surgery may also be needed for:

  • Bite alignment if the jaw is not aligned properly
  • Improving the facial appearance and function

A cleft defect can make it difficult for your child to eat or drink. Your doctor may give your child a dental plate, which is placed in the roof of the mouth. It should make it easier to eat and drink until surgery can be done.

Cleft palates may also be associated with ear and hearing problems. If your child has a middle ear infection or fluid build-up, your doctor may recommend:

  • Medications to treat infection or prevent fluid build-up
  • Surgery to drain built-up fluid and prevent future infections

Hearing testing should be done regularly. Rarely, children with cleft palate benefit from hearing aids.

Cleft Complications

Complications include:

  • Feeding problems, especially with cleft palate
  • Problems with speech development
  • Dental problems, including missing teeth, especially when cleft lip extends to the upper gum area
  • Symptoms of middle ear infections
  • Hearing problems
  • Symptoms of sleep-disordered breathing
