Cleft Palate
Disease Details
Family Health Simplified
- Description
- A cleft palate is a congenital deformity where the roof of the mouth (palate) does not fully close, creating an opening that can affect eating, speaking, and ear health.
- Type
- Cleft palate is a congenital malformation. Its genetic transmission can be multifactorial, involving a combination of genetic and environmental factors. There are also specific syndromes, like Van der Woude syndrome, where the inheritance can follow an autosomal dominant pattern.
- Signs And Symptoms
-
Signs and symptoms of a cleft palate include:
1. A visible gap or opening in the roof of the mouth.
2. Feeding difficulties, particularly in infants.
3. Nasal speaking voice.
4. Frequent ear infections and hearing problems.
5. Dental issues, such as missing, misaligned, or extra teeth.
6. Difficulty with speech development and articulation.

- Prognosis for individuals with cleft palate varies based on the severity of the condition and the treatment received. Early surgical intervention, typically performed within the first year of life, can significantly improve outcomes. Post-surgery, most children will require speech therapy and possibly additional surgeries or dental care as they grow. With comprehensive treatment, many individuals with cleft palate can achieve normal speech and good overall health. Early multidisciplinary care is essential for optimal results.
- Onset
- The onset of a cleft palate, also referred to as a congenital abnormality, occurs during fetal development. Specifically, it typically arises between the 6th and 9th weeks of pregnancy when the tissues that form the roof of the mouth fail to fuse properly. This condition is present at birth.
- Prevalence
- The prevalence of cleft palate varies geographically and ethnically but generally occurs in approximately 1 in 1,000 live births.
- Epidemiology
-
Cleft lip and palate occurs in about 1 to 2 per 1000 births in the developed world.Rates for cleft lip with or without cleft palate and cleft palate alone varies within different ethnic groups.
According to CDC, the prevalence of cleft palate in the United States is 6.35/10000 births and the prevalence of cleft lip with or without cleft palate is 10.63/10000 births. The highest prevalence rates for cleft lip, either with or without cleft palate are reported for Native Americans and Asians. Africans have the lowest prevalence rates.
Native Americans: 3.74/1000
Japanese: 0.82/1000 to 3.36/1000
Chinese: 1.45/1000 to 4.04/1000
White Americans: 1.43/1000 to 1.86/1000
Latin Americans: 1.04/1000
Africans: 0.18/1000 to 1.67/1000Cleft lip and cleft palate caused about 3,800 deaths globally in 2017, down from 14,600 deaths in 1990.Prevalence of "cleft uvula" has varied from 0.02% to 18.8% with the highest numbers found among Chippewa and Navajo and the lowest generally in Africans. - Intractability
- Cleft palate is not considered intractable. It can be effectively treated with surgical intervention, often performed in infancy or early childhood. Additional treatments, such as speech therapy and orthodontic care, can address resultant issues and improve outcomes.
- Disease Severity
- Cleft palate severity can vary widely among individuals. The condition involves an opening or split in the roof of the mouth that can affect eating, speaking, and hearing. The severity is often classified based on the extent of the cleft, ranging from a small notch to a large gap that may involve the hard and/or soft palate. Treatment typically includes surgery, but may also require dental and speech therapy.

- Pathophysiology
- The pathophysiology of cleft palate involves a failure in the fusion of the palatal shelves during embryonic development. This typically occurs between the 6th and 9th weeks of pregnancy. The disruption in normal tissue fusion can be influenced by a combination of genetic and environmental factors, including maternal smoking, diabetes, and certain medications taken during pregnancy. This results in an opening or split in the roof of the mouth, which can affect feeding, speech, and increase the risk of ear infections.
- Carrier Status
- Carrier status for cleft palate is often linked to genetic factors. Cleft palate can be inherited in multifactorial inheritance patterns, where both genetic and environmental factors play a role. Individuals may carry gene mutations associated with an increased risk of having a child with a cleft palate, but it is typically not associated with a single gene mutation that straightforwardly defines carrier status. Genetic counseling can help determine the likelihood of carrying genetic components that may contribute to cleft palate.
- Mechanism
-
Cleft palate is a congenital condition where there is an opening or split in the roof of the mouth because the tissue did not fuse together during pregnancy. Here are the details on its mechanism and molecular mechanisms:
**Mechanism:**
1. **Embryonic Development:** Normally, during embryonic development, the tissues that form the palate fuse together between the 6th and 9th weeks of pregnancy. Failure in this fusion process results in a cleft palate.
2. **Tissue Growth and Fusion:** The tissues involved in forming the palate grow towards each other and fuse at the midline. Disruption in this process can lead to a cleft.
**Molecular Mechanisms:**
1. **Genetic Factors:** Mutations or variations in several genes, such as IRF6, MSX1, PVRL1, and TBX22, can contribute to the failure of palate fusion.
2. **Signaling Pathways:** Important signaling pathways, including the Sonic hedgehog (Shh), Bone morphogenetic protein (BMP), and Transforming growth factor-beta (TGF-β) pathways, are crucial for normal palate development. Disruptions in these pathways can cause cleft palate.
3. **Environmental Influences:** Maternal exposure to certain environmental factors, such as smoking, alcohol, certain medications, and nutritional deficiencies (like folic acid), can interact with genetic predispositions and affect molecular pathways, increasing the risk of cleft palate.
4. **Cellular Processes:** Abnormalities in cellular processes such as cell proliferation, differentiation, migration, and apoptosis (programmed cell death) can hinder the proper development of the palate.
Understanding the intricate balance of these factors is essential for comprehending the etiology of cleft palate and for developing potential preventative and therapeutic measures. - Treatment
-
Cleft lip and palate is very treatable; however, the kind of treatment depends on the type and severity of the cleft.
Most children with a form of clefting are monitored by a cleft palate team or craniofacial team through young adulthood. Care can be lifelong and are looked after by craniofacial cleft teams often consist of: cleft surgeons, orthodontists, speech and language therapists, restorative dentists, psychologists, ENT surgeons and audio-logical physicians. Treatment procedures can vary between craniofacial teams. For example, some teams wait on jaw correction until the child is aged 10 to 12 (argument: growth is less influential as deciduous teeth are replaced by permanent teeth, thus saving the child from repeated corrective surgeries), while other teams correct the jaw earlier (argument: less speech therapy is needed than at a later age when speech therapy becomes harder). Within teams, treatment can differ between individual cases depending on the type and severity of the cleft. - Compassionate Use Treatment
-
Compassionate use treatment for cleft palate typically involves access to experimental or investigational therapies for patients who cannot be treated satisfactorily by available options. Some off-label or experimental treatments for cleft palate might include:
1. **Tissue Engineering and Regenerative Medicine**: These techniques aim to stimulate tissue growth to repair the cleft defect, though they are primarily in research phases.
2. **Stem Cell Therapy**: An experimental approach where stem cells are used to promote tissue regeneration in the palate.
3. **Growth Factors**: Investigating the use of growth factors like bone morphogenetic proteins (BMPs) to enhance bone and tissue repair, though this is still largely experimental.
All these treatments are subject to ongoing research and are not yet standard practice. Access may be limited to clinical trials or specific compassionate use programs. - Lifestyle Recommendations
-
Cleft palate is a congenital condition where there is an opening in the roof of the mouth due to incomplete fusion during fetal development. Here are some lifestyle recommendations for managing and supporting someone with a cleft palate:
1. **Nutritional Support**:
- Ensure the individual gets adequate nutrition, which might involve special feeding techniques or devices to assist with feeding in infants.
- Pureed or soft foods may be recommended to make eating easier and more comfortable.
2. **Oral Hygiene**:
- Maintain good oral hygiene to prevent infections and dental issues, as individuals with cleft palate are more susceptible to these.
3. **Regular Medical Follow-Up**:
- Regular visits to a team of healthcare providers, including pediatricians, dentists, and ear, nose, and throat (ENT) specialists, are essential.
- Speech therapy and audiology services should be utilized as needed to address any speech and hearing issues.
4. **Avoid Smoking and Alcohol**:
- Avoid smoking and alcohol consumption during pregnancy to reduce the risk of cleft palate in unborn children.
- For those with cleft palate, a smoke-free environment will reduce respiratory issues.
5. **Social and Psychological Support**:
- Engage in support groups and counseling to address any emotional or social challenges.
- Encourage participation in normal activities and provide a supportive and understanding environment to boost confidence and social skills.
Adopting these lifestyle recommendations can help in managing the condition and improving the quality of life for individuals with a cleft palate. - Medication
- Cleft palate is primarily treated through surgical intervention. Medications are generally not used to "treat" the cleft palate itself but may be prescribed to manage pain or prevent infection post-surgery. Common medications include analgesics for pain relief and antibiotics to prevent or treat infections. Pre-surgical care may also involve nutritional support and other interventions to ensure the child is healthy enough for surgery.
- Repurposable Drugs
- There are currently no well-established repurposable drugs specifically for the treatment of cleft palate. Management typically involves surgical repair and multidisciplinary care, including speech therapy, dental care, and sometimes psychological support. Research is ongoing, but drug repurposing has not yet yielded definitive candidates specifically for the treatment of cleft palate.
- Metabolites
- Cleft palate is a congenital condition where there is an opening or split in the roof of the mouth due to the tissues not fusing together during fetal development. Currently, there are no specific metabolites directly associated with cleft palate that are commonly used for diagnosis or treatment. The condition is typically identified through physical examination and prenatal imaging. Treatment often involves surgical intervention to repair the palate and supportive therapies such as speech therapy.
- Nutraceuticals
-
Nutraceuticals are dietary supplements or food products that reportedly provide health benefits beyond basic nutrition. For cleft palate, there is limited evidence supporting the effectiveness of nutraceuticals in its prevention or treatment. Folic acid supplementation before and during early pregnancy has been shown to reduce the risk of some congenital disabilities, including cleft palate, although it isn't considered a nutraceutical per se.
Regarding nanotechnology (nan), its application in cleft palate treatment is still under research. Nanotechnology might offer future advancements in personalized medicine, drug delivery, and tissue engineering, potentially contributing to improved outcomes in surgical repair and postoperative care.
However, as of now, surgical intervention remains the standard treatment for cleft palate, with supportive therapies like speech therapy and dental care also playing crucial roles. - Peptides
- Cleft palate is a congenital condition characterized by an opening or split in the roof of the mouth. Peptides, which are short chains of amino acids, can play a role in tissue repair and regeneration, and they are sometimes studied for their potential in enhancing wound healing after surgical corrections for cleft palate. Nanotechnology can also be applied in this context to improve targeted drug delivery, potentially aiding in tissue regeneration and reducing recovery times. Research in these areas is ongoing to develop effective treatments and improve outcomes for individuals with cleft palate.
