Now Know All about Cleft Palate: Cause, Symptoms, Diagnosis, Treatment

A cleft palate is a congenital birth defect that occurs when the roof of the mouth (palate) does not fully develop during fetal growth, leaving an opening or split. It can affect the soft palate (the back part of the roof of the mouth), the hard palate (the bony front part), or both. A cleft palate may occur with or without a cleft lip, a similar condition with a gap or split in the upper lip.

It is one of the most common congenital anomalies, affecting approximately 1 in every 1,700 births globally. Early diagnosis and treatment are critical to normal feeding, speech development, and overall health. (Source)

What is Cleft Palate?

It occurs when the tissues that form the roof of the mouth fail to join together completely during pregnancy, leaving a gap. This opening can be either small or extend across the entire roof of the mouth, affecting both the hard and soft palate. The cleft may also extend to the nasal cavity, causing further breathing, feeding, and speaking complications.

There are three main types of this palate:

1. Incomplete Cleft Palate: Only part of the palate is affected, often the soft palate at the back of the mouth.
2. Complete Cleft Palate: The split affects the entire palate, including both the hard and soft palate.
3. Cleft Lip with Cleft Palate: This occurs when a child has both a cleft lip and a cleft palate, affecting the lip, gums, and roof of the mouth. (Source)

How is Cleft Palate Caused?

The exact cause of it is not always known, but it is thought to result from a combination of genetic and environmental factors. These factors can disrupt the normal development of the facial structures during early pregnancy, typically between the 6th and 9th weeks of gestation. Potential causes include:

1. Genetic Mutations: Certain genes are involved in the development of facial tissues, and mutations in these genes can increase the risk of cleft palate.
2. Environmental Factors: External factors during pregnancy, such as maternal smoking, alcohol consumption, certain medications, or infections, can influence the development of the palate. (Source)

How Does Cleft Palate Spread?

It is not a contagious condition; it does not “spread” from one individual to another. However, it can run in families, particularly when a genetic predisposition is present.

Risk Factors for Cleft Palate

Several factors can increase the likelihood of a baby being born with this:

1. Family History: A family history of this or cleft lip increases the risk. Genetic predisposition plays a role, and the chances are higher if either a parent or a sibling has the condition.
2. Maternal Smoking and Alcohol Use: Women who smoke or consume alcohol during pregnancy are at higher risk of having a baby with a cleft palate.
3. Poor Prenatal Nutrition: Lack of essential nutrients like folic acid during pregnancy has been linked to an increased risk of birth defects, including cleft palate.
4. Medications During Pregnancy: Certain medications, such as anti-seizure drugs, can increase the risk of this if taken during the first trimester of pregnancy.
5. Diabetes: Pregnant women with uncontrolled diabetes may have a higher risk of having a child with a cleft palate.
6. Obesity: Maternal obesity has been linked to an increased risk of birth defects, including cleft palate. (Source)

Symptoms of Cleft Palate

The primary sign of it is the visible gap or split in the roof of the mouth. However, other symptoms may accompany the condition, including:

• Feeding difficulties: Babies with this may struggle to feed because they cannot create the suction needed to nurse or drink from a bottle.
• Nasal Regurgitation: Milk may come out of the baby’s nose while feeding due to the opening between the mouth and the nasal cavity.
• Speech problems: Older children may have difficulty pronouncing certain sounds and may develop a nasal-sounding voice.
• Frequent ear infections: The cleft can affect the Eustachian tubes, leading to chronic ear infections, which may impact hearing.
• Dental issues: Children with this often have dental problems, such as missing or misaligned teeth. (Source)

Diagnosis of Cleft Palate

It can often be diagnosed through a prenatal ultrasound as early as the second trimester. If not detected during pregnancy, the condition is usually identified at birth during a physical examination. Additional tests, such as imaging or genetic testing, may be conducted to determine the severity and check for other associated conditions.

Treatment for Cleft Palate

Treatment for this typically involves multiple stages and a multidisciplinary team, including surgeons, orthodontists, speech therapists, and other specialists. The primary treatment options include:

1. Surgery:

• Palatoplasty: The main surgical procedure to repair the cleft palate, typically performed when the child is between 6 and 18 months old. The surgeon closes the gap in the roof of the mouth, allowing for normal feeding and speech development.
• Additional Surgeries: Depending on the severity of the cleft, additional surgeries may be needed to improve the function and appearance of the mouth and face. For example, pharyngoplasty may be performed to help with speech.

2. Speech Therapy:

• After surgery, many children require speech therapy to address any speech difficulties. A speech therapist helps children learn how to pronounce sounds correctly and overcome any challenges associated with the cleft.

3. Orthodontic Care:

• Dental issues, such as misaligned teeth or missing teeth, are common in children with cleft palate. Braces, orthodontic appliances, and sometimes additional surgeries are needed to correct dental problems.

4. Hearing Management:

• Children with this are prone to ear infections and hearing loss due to fluid buildup in the middle ear. Ear tubes may be inserted to prevent infections and improve hearing. (Source)

Can Cleft Palate Be Prevented?

While it is not always possible to prevent it, certain steps can reduce the risk during pregnancy:

• Prenatal Vitamins: Taking folic acid supplements before and during pregnancy may reduce the risk of cleft palate and other birth defects.
• Avoiding Smoking and Alcohol: Pregnant women should avoid smoking and alcohol consumption, which are known risk factors.
• Proper Medication Use: Consult with a healthcare provider before taking any medication during pregnancy to avoid drugs that may increase the risk of birth defects.
• Healthy Diet: Maintaining a balanced diet with essential nutrients, such as folic acid, is crucial for preventing congenital abnormalities. (Source)

Is Cleft Palate Hereditary?

It can have a genetic component, meaning it may be passed down through families. If one parent has a cleft palate, the child’s risk of developing the condition increases. Additionally, if one child in the family has a cleft palate, the risk of future children being born with the condition is higher. However, environmental factors also contribute to the development of cleft palate, making it a condition with both genetic and environmental influences.

Can Cleft Palate Be Cured?

Yes, it can be effectively treated and cured through surgery. Early intervention and treatment allow children with it to live healthy, normal lives with few long-term complications. While additional therapies, such as speech therapy or orthodontic care, may be needed as the child grows, the overall prognosis is very good. (Source)

Conclusion

It is a common birth defect affecting the roof of the mouth, often associated with feeding, speech, and dental issues. Though the exact cause is a mix of genetic and environmental factors, early diagnosis and treatment can provide a full and healthy life for affected children. Surgical repair, combined with speech therapy and dental care, effectively resolves most of the complications associated with this condition.
