About Cleft Lip & Palate

One in seven hundred babies are born with cleft lip and/or cleft palate, which is an incomplete closure of the upper lip and/or roof of the mouth. This causes a gap to occur in the affected area, involving the skin, muscle, bone, and the lining of the mouth. A cleft lip and/or palate can be unilateral, involving only one side of the mouth, or bilateral, involving both sides. A cleft lip often occurs in conjunction with a cleft palate; however, this is not always the case.

A cleft lip and/or palate can be diagnosed in utero as early as the 13th week. Usually, a cleft lip is easier to be seen and sometimes a palate is not recognized until birth. Having an early diagnosis allows families to receive early intervention and get referred to a craniofacial multidisciplinary team even before their child is born. Craniofacial teams usually consist of a plastic/craniofacial surgeon, pediatrician, orthodontist, pediatric dentist, speech and language specialist, otolaryngologist (ear-nose-throat specialist) and an audiologist (hearing specialist).

 Cause and Risks

While the cause of cleft lip and palate is uncertain, a child’s genes and
some maternal health conditions such as having diabetes, smoking, drinking, or lack of Vitamin B can increase risk. In addition, poverty, nutrition, and environmental factors play a large role in Latin America as children there are roughly two times as likely to be born with orofacial clefts than children in the U.S.

Health and Developmental Impacts

Children born with a cleft lip or palate often face one or more of these health problems: feeding/eating disorders, speech and language development, breathing and hearing difficulties, and dental problems.

Speech, Hearing Therapy, Orthodontia

Children who are undergoing treatment to repair orofacial cleft often need help learning to speak and communicate before and after surgery; therefore early intervention with a registered Speech and Language Pathologist (SLP) is often essential. SLPs will often be involved as early as birth to help mothers with feedings and nutrition.

Psychological and Emotional Impacts

Even with comprehensive, interdisciplinary medical care from a cleft team, the journey for these children and their families is a long and difficult one. Social/emotional care is essential for the family and child while undergoing treatment. Parents and family members also benefit from counseling and practical skill development that help them provide the emotional and functional support these children need. At Austin Smiles, we work locally to ensure children and their families undergoing cleft treatment have access to resources and a sense of community to help ensure they are not alone on their journey.

The cause of orofacial clefts in most infants are unknown but thought to be a combination of genetics and other environmental factors. Some of these environmental factors are smoking during pregnancy, gestational diabetes, and the use of certain medications during pregnancy. In genetic studies regarding cleft lip/palate (CLP), causes are often classified as either “non-syndromic” or “syndromic”. A genetic syndrome is defined as a group of symptoms that occur together which are caused in whole or part by a change in DNA sequence compared to the normal sequence. But when it comes to defined genetic factors, they are not just limited to the syndromic cases. Recent research indicates that there is a strong link between the MTHFR gene and cleft lip/palate. Coincidentally, this gene is on the list of conditions tested in Texas during newborn screening; the condition is called homocystinuria which can cause deficiency in folate. So, when it comes to both syndromic and non-syndromic cases of CLP, understanding the genetic links to your child’s cleft can help inform future health practices.
