Cleft: Understanding the Causes, Symptoms, and Treatments

Introduction

Cleft is a common birth defect that affects the lip and/or palate, resulting in various disabilities and complications. It can lead to difficulties in feeding, speaking, and hearing, as well as dental problems. Clefts can be caused by a combination of genetic and environmental factors, and in most cases, the cause is not fully understood.

Causes of Cleft

The causes of cleft lip and cleft palate are complex and involve both genetic and environmental factors. In most cases, the cause is unknown, but it is believed to be a result of a combination of genes and other factors, such as exposure to certain chemicals or medications during pregnancy. Some drugs that may cause clefts include anti-seizure/anticonvulsant drugs, acne drugs containing Accutane, and methotrexate.

Cleft Lip

Cleft lip occurs when the tissue that makes up the lip does not join together completely during pregnancy. The opening in the lip can be a small slit or a large opening that goes through the lip into the nose. Cleft lip can occur on one or both sides of the lip or in the middle of the lip.

Cleft Palate

Cleft palate occurs when the tissue that makes up the roof of the mouth does not join together completely during pregnancy. In some cases, both the front and back parts of the palate are open, while in others, only part of the palate is open.

Symptoms and Diagnosis

Babies with cleft lip and cleft palate may have various symptoms, such as difficulty feeding, food or liquid coming out of their nose when they try to eat, delayed speech or trouble speaking, ear infections, hearing loss, missing, crooked, or small teeth, and teeth and jaws that don't line up evenly. An ultrasound during pregnancy can sometimes show a cleft lip, with or without cleft palate, but it may not be apparent until the baby has trouble feeding or later in life.

Treatment

Treatment for cleft lip and cleft palate varies depending on the severity of the cleft, the child's age and needs, and the presence of associated syndromes or other birth defects. It may involve surgery, speech therapy, and dental and orthodontic treatments to address feeding, hearing, and dental issues.

Prevention

Since the causes of cleft lip and cleft palate are not fully understood, prevention is difficult. However, pregnant women can take steps to reduce the risk, such as avoiding exposure to certain chemicals and medications, maintaining a healthy lifestyle, and seeking regular prenatal care.

Conclusion

Cleft lip and cleft palate are complex birth defects that can lead to various disabilities and complications. While the causes are not fully understood, it is believed to be a result of a combination of genetic and environmental factors. Treatment and management vary depending on the severity of the cleft and the presence of associated syndromes or other birth defects.
