Cleft lip and cleft palate

  • Cleft lip and cleft palate describe an abnormal gap in either the upper lip or the roof of the mouth (the palate). It occurs when some parts of the mouth fail to join together during early pregnancy. The lip and palate develop separately, which means it is possible for a baby to be born with only a cleft lip, only a cleft palate, or a combination of both.

    Clefts that occur only on one side are called unilateral clefts. When the cleft affects both sides, it is called a bilateral cleft.

    Cleft lip and cleft palate can occur by themselves, or in some cases along with other problems. Most of the time, cleft lip or cleft palate is detected during routine scans in pregnancy.

    What causes cleft lip and cleft palates?

    Often the cause of a cleft lip and palate is unknown. Sometimes it can happen because there is a family history of the condition. However, sometimes a child is born with the condition when there is no family history and no known cause of the condition.

    Treatment

    The treatment required for a child with a cleft lip or cleft palate depends on how severe the condition is at birth. A small cleft lip may need only one operation in the first few months of life. A child with a large cleft involving the lip and palate will need several operations. Your child's surgeon will explain your child's surgical plan to you.

    Your child will usually only need to stay in hospital for one to three days for surgical procedures.

    Depending on their needs, your child may need to have ongoing care from a cleft team. This might include a/an:

    • clinical nurse consultant
    • audiologist
    • dental specialist
    • ear, nose and throat (ENT) surgeon
    • oral and maxillofacial surgeon
    • paediatrician
    • plastic surgeon
    • speech pathologist.

    Your child will see the cleft team from birth until their face has finished growing (usually in their late teens).

    How a cleft lip and palate affects children

    Your child may be affected in a number of ways by a cleft lip and/or palate, and there are a number of important areas to consider in their care.

    Hearing

    Children affected by cleft palate are more likely to have hearing problems and fluid in the middle ear.

    • Every baby with a cleft palate needs to have their hearing monitored closely by a hearing specialist (audiologist).  A hearing assessment should be arranged for when your baby is around four weeks old, and repeated again around 12 weeks of age.
    • Annual hearing tests are recommended during early childhood for children with a history of cleft palate.

    Speech

    The palate is very important in speech.

    • Children with a cleft palate may have trouble pronouncing consonants (p, b, t, d, k, g, f, v, s, z) and sounds like sh and ch, and they may have a very nasally sounding voice.
    • They may make unfamiliar sounds, which make it difficult to understand what your child is saying. This is very frustrating to the child.

    After surgery, speech therapy is usually helpful in eliminating these sounds and developing the sounds your child needs for speech.

    Teeth

    Many children with a cleft of the lip and palate will have missing teeth, particularly in the line of the cleft.

    They may also have extra teeth, misshapen or malformed teeth. Because of this, their teeth can be crowded, tilted or rotated.

    • Children with a cleft should be seen by a dentist shortly after their first teeth come through. It is important to see a dentist experienced in the care of people with clefts.
    • It is important that your child's teeth are looked after carefully. Your child may want to have braces or other dental treatment in the future to improve their appearance, and healthy teeth are essential for this.

    Feeding

    For information on feeding a baby with cleft lip, palate or both, see our fact sheet Cleft lip and palate – infant feeding.

    Key points to remember

    • Cleft lip and palate are an abnormal gap in the upper lip or the roof of the mouth.
    • Cleft lip and cleft palate affect infant feeding, hearing, speech and teeth.
    • Your child will need hearing tests, and monitoring by a dentist and speech pathologist experienced in cleft care.
    • A child born with cleft lip and cleft palate will require several operations to repair the cleft.

    Common questions our doctors are asked

    How likely is it my child will look normal after plastic surgery? 

    It depends on how severe the cleft is and whether it affects the lip or palate or both. A cleft palate will have very little impact on your child's appearance. Surgery nowadays achieves excellent results with children's appearance and teeth. Cleft lip repair is always associated with a scar.

    After surgery, will my child be able to speak properly? 

    Your child's speech pathologist will help your child to create all the sounds needed for speech, which will be easier for them once the cleft palate has been repaired through surgery.
