Understanding cleft lip and cleft palate

What are cleft lip and cleft palate?

Early in pregnancy, tissues that form a baby’s mouth and lips fuse together. A cleft, or gap, happens when these tissues do not align. The cleft can be on one side (unilateral) or on both sides (bilateral).

A cleft can occur in the lip or in the roof of the mouth, affecting the palate. Clefts range from small openings in the back of the mouth to large gaps affecting most of the roof of the mouth.

Clefts may occur in the lip, palate or both. Cleft lip and cleft palate together is most common.

Cleft lips and cleft palates can cause:

  • Problems with nursing or drinking from a bottle
  • Speech and hearing problems
  • Ear infections
  • Uneven teeth

Who gets cleft lip and cleft palate?

Cleft lip and cleft palate are common birth defects, and the most common medical issue affecting the head and neck. Each year in the United States, about 2,650 babies are born with a cleft palate and about 4,440 babies are born with a cleft lip, according to the Centers for Disease Control and Prevention.

What causes cleft lip and cleft palate?

Heredity plays a role in cleft lip and cleft palate. You have a higher risk of having a baby with a cleft if you already had a baby with a cleft or if you or your partner has a cleft.

Cleft lip and cleft palate are usually not linked to environmental factors. But researchers continue to study behaviors that may affect a baby’s development in early pregnancy.

According to the CDC, these factors can increase the risk of cleft lip or cleft palate.

  • Parents who smoke during pregnancy have a higher risk of having a baby with a cleft.
  • Parents with diabetes diagnosed before pregnancy (not gestational diabetes) have a higher risk of having a baby with a cleft.
  • Parents who use epilepsy medicines such as topiramate or valproic acid during the first trimester have a higher risk of having a baby with a cleft.

Signs and symptoms of cleft lip and cleft palate

A cleft lip is often diagnosed during pregnancy by a routine ultrasound. A cleft palate is usually diagnosed after birth because the inside of a baby’s mouth can’t be seen on an ultrasound.

A cleft palate may affect only the soft palate (fleshy tissue at the back of the mouth). It may not be visible. The first sign of the cleft may be trouble latching on to the breast or bottle, or inconsistent suction when nursing.

Other types of clefts may not be diagnosed until later in childhood. For example, a submucous cleft palate is a cleft in the roof of the mouth that is usually covered by skin.

Screening

Ultrasound technicians look for signs of a cleft lip during prenatal ultrasounds. At OHSU, we use a state-of-the-art 3D ultrasound, making it easy to see signs of a cleft as early as possible.

If there are signs of a cleft lip, you can start learning about treatment options right away. Soon after your baby is born, your provider will examine the cleft lip and look for a cleft in the palate. Some types of clefts are covered with skin, making them hard to see. If your child’s care provider sees signs of a cleft, they can refer you to specialists like the ones on our team.

Types of clefts

The type of cleft your child has will determine the best treatment. Clefts may be:

  • Incomplete: Partial fusion of the lip or palate
  • Complete: No fusion of the lip or palate

A cleft lip may appear with or without a cleft palate. The most common combination is a cleft of the hard and soft palate and a cleft lip on one side.

Cleft lip


Types of Cleft Lip

This illustration shows three side-by-side views of an infant’s mouth, nostrils and tip of the nose. One shows a unilateral incomplete cleft lip, with a gap forming an upside-down V from one side of the lip to under the nose. A depiction of a unilateral complete cleft lip shows a gap shaped like a river extending from one side of the mouth into the nostril above it. The depiction of a bilateral complete cleft lip shows a gap running from mouth to nose on both sides, flaring at each end.
A unilateral incomplete cleft lip means a “cleft” or gap is on one side of the mouth and does not reach the nose. A unilateral complete cleft lip is on one side and extends into the nose. A bilateral complete cleft lip affects both sides and extends into the nose.

  • Unilateral incomplete: The cleft appears on one side of the lip and does not extend into the nose. The gum line on the same side may be affected.
  • Unilateral complete: The cleft appears on one side of the lip and extends into the nose. The gum line on the same side may be affected.
  • Bilateral incomplete: The cleft affects both sides of the lip but doesn't reach the nose.
  • Bilateral complete: The cleft affects both sides of the lip and continues into the nose.
  • Microform: A subtle cleft appears as a notch, groove or scar on one or both sides of the lip. This cleft may not require surgery.

Bilateral clefts may be asymmetrical, or complete on one side and incomplete on the other.

Cleft palate


Types of Cleft Palate

This illustration shows side-by-side views of an infant’s open mouth. One shows an incomplete cleft palate, with a roughly heart-shaped gap in the soft palate at the back of the mouth. The other shows a complete cleft palate, with the cleft running in a jagged diagonal line from the soft palate at the back of the mouth through the hard palate in the front.
These are the two most common types of cleft palate. An incomplete cleft palate (left) means there’s a “cleft,” or gap, in the soft palate at the back of the mouth. With a complete cleft palate, the cleft affects both the soft and the hard palate, at the front of the mouth.

Cleft palates are grouped into three types:

  • Incomplete cleft palate: A cleft in the back of the mouth, in the soft palate.
  • Complete cleft palate: A cleft affecting the hard and soft parts of the palate. The mouth and nose cavities are open to each other.
  • Submucous cleft palate: A cleft in the muscles of the soft palate, but not in the lining of the palate. This cleft may not be seen in an exam.
