What are Orofacial Clefts?

Orofacial clefts, also known as cleft lip and palate, are birth defects that occur when the tissues of the mouth or lip don't form properly during fetal development. This can result in an opening or split in the roof of the mouth (cleft palate) or a split in the lip (cleft lip).

Types of Orofacial Clefts

There are two main types of orofacial clefts:

• Cleft Lip: A split in the upper lip, which can be unilateral (on one side) or bilateral (on both sides).
• Cleft Palate: An opening or split in the roof of the mouth.

Causes and Risk Factors

While the exact causes of orofacial clefts are unknown, research suggests that they may be caused by a combination of genetic and environmental factors. Some risk factors include:

• Family history: Having a family history of orofacial clefts increases the risk.
• Genetic mutations: Certain genetic mutations can increase the risk of developing an orofacial cleft.
• Environmental factors: Exposure to certain chemicals or substances during pregnancy may also contribute to the development of an orofacial cleft.

Prevalence and Treatment

Orofacial clefts are relatively common, with approximately 1 in every 700 births affected. Fortunately, they can be treated with surgery and other interventions, which can significantly improve quality of life and overall health outcomes.

Common Signs and Symptoms of Orofacial Cleft

Orofacial cleft, which includes cleft lip and cleft palate, can manifest in various ways, affecting an individual's quality of life. Here are the common signs and symptoms associated with this condition:

• Feeding difficulties: Infants with cleft palate may experience trouble feeding due to the incomplete formation of the roof of the mouth [1].
• Trouble breathing: Children with orofacial cleft may have difficulty breathing, especially if the cleft is severe [6].
• Frequent ear infections: Orofacial cleft can increase the risk of ear infections and hearing loss in children [6].
• Speech problems: As they grow older, individuals with cleft lip or palate may experience speech difficulties due to the abnormal formation of the upper lip and roof of the mouth [6].
• Eye problems: Some people with orofacial cleft may be more prone to eye issues, such as crossed eyes or other vision problems [7].

It's essential for parents or caregivers to work closely with a care team experienced in treating craniofacial conditions like orofacial cleft. Early intervention and proper treatment can significantly improve the quality of life for individuals affected by this condition.

Diagnostic Tests for Orofacial Clefts

Orofacial clefts, including cleft lip and palate, can be diagnosed using various diagnostic tests. Here are some of the common tests used to diagnose these conditions:

• Ultrasound: An ultrasound test can often show a cleft lip alone or a cleft lip and palate at about 16 weeks into pregnancy [8]. A routine ultrasound during pregnancy can also diagnose orofacial clefts, especially cleft lip [6].
• Blood tests: Blood tests may be conducted to rule out any underlying conditions that could be contributing to the cleft. This may include a complete blood count (CBC) and chromosomal studies if indicated [7].
• X-rays: X-rays may be taken to evaluate the extent of the cleft and to check for any other potential issues.
• Special tests: Depending on the individual case, special tests such as MRI or 3D/4D scans may be offered to know the extent of the cleft. However, these tests rarely alter the management of the condition [4].
• Referrals to specialists: If a specific diagnosis is made, the family may be referred to other specialists for further evaluation and counseling.

It's worth noting that most cases of cleft lip and palate are seen right away at birth, so special tests aren't always needed. However, in some cases, additional testing may be required to confirm the diagnosis or to rule out any underlying conditions.

What are Orofacial Clefts?

Orofacial clefts, also known as cleft lip and palate, are birth defects that occur when the tissues that form the mouth and lips do not develop properly during pregnancy. This can result in a gap or opening in the upper lip (cleft lip) and/or the roof of the mouth (cleft palate).

Treatment Options

The treatment for orofacial clefts typically involves surgery to close the gaps in the lip and palate, as well as other interventions such as speech therapy and dental work. The goal of treatment is to restore normal function and appearance.

• Surgery: Surgery is usually performed on infants with cleft lip and/or palate to close the gaps and improve feeding and breathing.
• Speech Therapy: Children with orofacial clefts may need speech therapy to help them develop proper articulation and communication skills.
• Dental Work: Regular dental check-ups are essential for children with orofacial clefts, as they are at higher risk of tooth decay and other oral health problems.

Other Considerations

It's worth noting that the treatment of orofacial clefts can be complex and may require a team of specialists, including surgeons, speech therapists, and dentists. Additionally, some medications have been linked to an increased risk of orofacial clefts in babies (see [4] for more information).

Differential Diagnosis of Orofacial Cleft

Orofacial cleft, a congenital deformity affecting the upper lip and/or palate, can be part of a larger syndrome or condition. It is essential to differentiate an isolated orofacial cleft from one with other associated anomalies, which may indicate a chromosomal abnormality or genetic condition.

Key Points:

• Isolated vs. Associated Anomalies: A differential diagnosis should consider whether the orofacial cleft is isolated or accompanied by other anomalies, which can narrow the differential diagnosis.
• Bilateral Cleft Lip with Asymmetry: Bilateral facial cleft with asymmetry in defect size may be mistaken for a different condition.
• Chromosomal Abnormality or Genetic Condition: The presence of other associated anomalies increases suspicion for a chromosomal abnormality or genetic condition.

Additional Considerations:

• A thorough examination and medical history are necessary to determine the presence of any additional anomalies.
• Genetic testing may be recommended in cases where a chromosomal abnormality or genetic condition is suspected.
