What is a cleft lip or palate?

A cleft lip or palate can result when parts of your lip, upper jaw or the roof of your mouth don't join properly. It happens early in pregnancy as the baby is developing.

The result is a 'cleft' or opening. This condition is called 'congenital' which means it is present at birth.

About one baby in every 800 in Australia is born with a cleft lip or palate.

What are the symptoms of a cleft lip or palate?

The type of cleft lip or palate depends on which parts don't join properly.

Cleft lip: The upper lip has 3 parts. There are 2 large parts at each side and a small part in the middle. A gap can happen if one or more of these 3 parts do not join together. It happens when the fetus is 7 to 9 weeks old. Sometimes a cleft lip can be just a small notch in the gum.

Cleft palate: The roof of the mouth is formed when the fetus is 10 to 12 weeks old. The bones and soft tissues move from the sides of the mouth and join in the middle. If this does not happen properly, there will be a gap in the roof. This can just be in the soft tissue at the back of the mouth. Sometimes the gap can go all the way from the back of the mouth to the gums.

Cleft lip and cleft palate: When the upper lip, gum and roof of the mouth do not join properly there can be a gap. It can happen when the fetus is about 12 weeks old. The cleft can be on one side only (unilateral), or on both sides (bilateral). The opening is between the mouth cavity and the nasal cavity.

How is a cleft lip or palate diagnosed?

A cleft lip or palate are usually noticed as soon as the baby is born. The condition will start to be managed right away.

Sometimes a cleft or lip palate is noticed during an ultrasound. This is usually at about 18 weeks of pregnancy.

If a cleft lip or palate is suspected during your ultrasound, the doctor may recommend an amniocentesis. This is a test of the amniotic fluid around the fetus, which looks for other birth defects.

You should talk about the benefits and the risks of having amniocentesis with your doctor.
