Cleft Palate and Cleft Lip: Causes and Treatment

gleneagles-cleft-lip-banner

A cleft refers to a gap or a split in the upper lip and/or roof of the mouth (palate). Cleft palate and cleft lip are birth defects that occur to a baby’s mouth or lip due to incomplete fusion of parts of the mouth during early pregnancy. A baby can have a cleft lip, a cleft palate, or both (orofacial clefts).

Cleft palate occurs when the tissue that makes up the roof of the mouth (palate) does not join together completely during pregnancy. This can result in an opening in the hard palate (the bony front portion of the roof of the mouth) and/or the soft palate (the soft back portion of the roof of the mouth). 

Cleft lip isan incomplete formation of the lip during foetal development. It can range from mild (notching of the lip) to severe (large opening from the lip up to the nose). A cleft lip can be unilateral (one side of the lip) or bilateral (both sides of the lip).

Risk factors

The causes of cleft palate and cleft lip are not fully understood, but they are believed to result from a combination of genetic and environmental factors. Here are some potential risk factors:

  • Family history of cleft palate/lip.
  • Folic acid deficiency.
  • Smoking during pregnancy.
  • Substance abuse during pregnancy (alcohol, illicit drugs).
  • Certain types of medications taken during pregnancy (anti-seizure medications, cancer drugs).
  • Diagnosed with diabetes before pregnancy.
  • Obesity during pregnancy.

Diagnosis

A cleft lip can often be identified during a routine prenatal ultrasound. It is typically noticeable during a newborn’s initial examination. However, certain types of cleft palate may not be as easily detected and might go undiagnosed until later in life.

Potential complications

Babies can have trouble breastfeeding because they cannot form a good seal around the nipple. Solid food and liquids may pass from the mouth back through the nose. 

Children with cleft palate are also more likely to have fluid buildup in the middle ear, leading to ear infections and hearing loss if left untreated or occurs repeatedly.

Children with cleft palate/lip tend to experience speech and language issues including sounding nasal, difficulty in articulating words, and ultimately, difficulty being understood. They are also prone to missing, malformed, or displaced teeth and cavities. They may experience defects of the alveolar ridge (bony upper gum that surrounds the teeth) which could prevent permanent teeth from appearing and premature loss of canine/incisor teeth.

If left untreated, these complications will negatively impact the growth and development of the affected children.

Treatment options

Services and treatments for children with orofacial clefts can vary based on the severity of the cleft, the child’s age and specific needs, and the presence of associated syndromes or other birth defects.

Surgical treatment

Cleft lip surgical repair is usually performed when the baby is between 3 and 6 months old, whereas cleft palate surgical repair is generally done between 9 and 18 months of age.

Non-surgical treatment

  1. Special feeding bottles and nipples may be used to help infants with cleft lip or palate feed more effectively. A feeding specialist or lactation consultant can provide guidance and support.
  2. Many children with cleft palate will require speech therapy to help them develop normal speech patterns. A speech-language therapist can work with the child to address any speech and language issues.
  3. Regular hearing evaluations are important, as children with cleft palate are at increased risk for ear infections and hearing loss. Ear tubes may be inserted to prevent fluid buildup and infections.
  4. Orthodontic treatment may be needed to correct misaligned teeth and bite issues. This can include braces and other dental appliances.
  5. Psychological support and counseling can be beneficial for the child and family to address any emotional and social challenges related to the cleft condition.
