Cleft Lip: 10 Causes, types and Treatment

 

A cleft lip is a congenital condition where there is an opening or gap in the upper lip. It can occur on one or both sides of the lip and can vary in severity. Cleft lips typically occur during fetal development when the tissue that forms the lip does not fully come together. The exact cause of cleft lips is not always known, but it is believed to be a combination of genetic and environmental factors. key factors associated with cleft lip are listed below:

Genetic Factors: Cleft lips can run in families, suggesting a genetic component. Specific genes that contribute to cleft lip risk have been identified in some cases.

Cleft lip is a congenital condition, meaning it is present at birth, and it can have genetic factors that contribute to its development. Genetic factors play a role in the susceptibility to cleft lip, but they often interact with environmental factors. Here's what we know about the genetic factors associated with cleft lip:

Family History: Cleft lip can run in families, suggesting a genetic component. If a parent or sibling has had a cleft lip, the risk of a child being born with a cleft lip is increased. However, it's not a straightforward inheritance pattern, and multiple genes are likely involved.

Complex Inheritance: Cleft lip is considered a complex trait, which means that it doesn't follow a simple Mendelian pattern of inheritance like some genetic disorders. Instead, it is influenced by multiple genes and their interactions. Researchers have identified several candidate genes that may be involved in cleft lip development, and these genes can vary among individuals.

Gene Mutations and Variants: Mutations or variants in specific genes have been associated with an increased risk of cleft lip. For example, mutations in genes such as IRF6, MSX1, and BMP4 have been linked to cleft lip and palate in some cases. However, it's important to note that not all individuals with cleft lip have these genetic mutations, and not all individuals with these mutations will develop cleft lip.

Gene-Environment Interactions: While genetics plays a role, cleft lip is also influenced by environmental factors. Factors such as maternal smoking, alcohol consumption during pregnancy, certain medications, and maternal nutrition can interact with genetic predisposition to increase the risk of cleft lip in the offspring.

Environmental Factors: Certain environmental factors during pregnancy may increase the risk of cleft lips, including maternal smoking, alcohol use, and certain medications. Folate deficiency during pregnancy has also been associated with an increased risk.

Multifactorial Causes: In many cases, cleft lips result from a combination of genetic and environmental factors. The interaction between these factors can increase the likelihood of a cleft lip.

Treatment for cleft lips typically involves a combination of surgical and non-surgical interventions, as well as ongoing care. Here are methods  of treatment:

Surgical Repair: The primary treatment for cleft lips is surgical repair. This surgery is usually performed when the child is a few months old, and the timing can vary based on the specific circumstances of the individual case. During the procedure, the surgeon will close the gap in the lip, improving its appearance and function. Multiple surgeries may be required over the years as the child grows.

Speech and Language Therapy:  These conditions can impact a child's ability to speak and communicate effectively. Speech and Language Therapy (SLT) plays a crucial role in helping children with cleft lip and palate develop their communication skills.

HERE'S HOW SLT CAN BENEFIT CHILDREN WITH CLEFT LIP AND PALATE:

Articulation and Speech Sound Development: Cleft lip and palate can affect the production of speech sounds due to anatomical differences. Speech therapy can help children learn how to pronounce sounds correctly, facilitating clearer and more understandable speech.

Resonance and Voice: Cleft palate can lead to hypernasal or nasal speech because of improper closure in the nasal cavity. Speech therapists work with children to develop appropriate resonance and voice control.

Language Development: Children with cleft lip and palate might face language delays or difficulties. SLT helps them with vocabulary development, sentence structure, and comprehension skills, promoting age-appropriate language development.

Feeding and Swallowing: Cleft lip and palate can interfere with feeding and swallowing. Speech therapists can provide guidance and exercises to improve these functions, ensuring proper nutrition and preventing related health issues.

Social and Pragmatic Skills: Effective communication involves not only speech and language but also social skills and pragmatic language. Speech therapists can help children with cleft lip and palate develop these skills, allowing them to interact with peers and adults effectively.

Counseling and Support: SLT also offers emotional and psychological support for children and their families. Dealing with a cleft lip or palate can be emotionally challenging, and speech therapists can offer guidance and strategies for coping with these challenges.

SLT for children with cleft lip and palate is typically a long-term process. It often involves a team of healthcare professionals, including speech therapists, pediatricians, otolaryngologists (ear, nose, and throat specialists), and plastic surgeons. Early intervention is critical to achieve the best results, and speech therapy is often initiated as early as a few months of age. The therapy plan is individualized to address each child's unique needs and progress.

Children born with cleft lips may have speech and language difficulties due to the opening in the roof of the mouth (palate) associated with cleft lip. Speech therapy can help address these issues and improve communication skills.

Dental and Orthodontic Care: Cleft lip and palate can also affect the alignment of teeth and the development of the jaw. Dental and orthodontic care is often needed to correct these issues.

Ear and Hearing Care: Some children with cleft lip may have ear and hearing problems due to issues with the Eustachian tube, which connects the middle ear to the back of the throat. Regular ear and hearing evaluations are important.

Psychological and Emotional Support: Coping with a cleft lip can be emotionally challenging for both the child and the family. Psychological and emotional support can help individuals and families navigate these challenges.

CONCLUSION

It's important for individuals with cleft lips to receive comprehensive care from a team of healthcare professionals, including surgeons, speech therapists, orthodontists, and other specialists, to address the physical and emotional aspects of the condition. Early intervention and ongoing care can help individuals with cleft lips lead healthy and fulfilling lives.
