Oral and facial clefts are among the most common and heartbreaking of birth defects. Clefts make feeding or even breathing difficult and can affect speech development.
But there's one other profound effect: an “abnormal” face caused by a cleft can have devastating consequences for a person's self-image and social relationships.
About 1 in 700 U.S. babies are born with some type of visible gap or “cleft.” It can occur in their upper lip, soft and hard palate, nose or occasionally extending to the cheek or eye region. We typically classify clefts as “unilateral” (affecting only one side of the face) or “bilateral” (affecting both sides).Â We're not completely sure on the root causes, but research so far has uncovered links with the mother's possible exposure to toxic substances, nutrient or vitamin deficiencies, or infections during fetal development.
Taking steps during pregnancy to minimize these exposures is certainly helpful. But what can be done for children born with a cleft?
A great deal, thanks to the development of surgical repair techniques over the last century. The surgical approach relies on the fact that the tissues required to repair the cleft already exist. They're simply distorted by the cleft break.
Even so, the road to restoration is a long and arduous one. Lip repairs usually take place at 3-6 months of age; palate (roof of the mouth) clefts are undertaken at 6-12 months. As the child's jaw and mouth structure develops, further surgeries may be needed to match earlier repairs with development.
Cleft repairs also require a team of specialists including a maxillofacial (oral) surgeon, orthodontist and general dentist. The latter plays an important role during the process, ensuring the child maintains good dental health through prevention and treatment of disease and dental work for at risk teeth.
The road to a normal life is difficult — but well worth it. A repaired cleft vastly improves a child's health and well-being. Moreover, it restores to them something the rest of us might take for granted — a normal face and smile.
One of the most common and anguish-filled birth defects is a cleft lip or palate (roof of the mouth). Not only do clefts disrupt the normality of a child’s facial appearance, they can also lead to problems with chewing, speech and the long-term health of teeth and gums.
A cleft is a tissue gap that occurs during fetal development, usually in the first trimester, in which parts of the baby’s face fail to unite. Why this occurs is not fully understood, but vitamin imbalances in the mother, exposure to radiation or other toxic environments, or infections are all believed to play a role.
Facial clefts are classified as either incomplete, in which there is some but not full tissue fusion, or complete, with no fusion at all. A cleft can be unilateral, affecting only one side of the face, or bi-lateral, affecting both sides. During infancy a cleft can adversely affect a child’s ability to nurse, and it sometimes disrupts breathing. As the child grows, speech patterns may be severely disrupted and their teeth and bite may not develop properly.
Fortunately, there have been dramatic advances in cleft repair over the past sixty years. It’s actually a process that can span a child’s entire developmental years and involve the expertise of a number of surgical and dental specialists. For a cleft lip, the initial surgical repair to realign and join the separated tissues usually occurs around three to six months of age; repair of a cleft palate (where the gap extends into the roof of the mouth) between 6 and 12 months.
Subsequent procedures may be needed in later years to refine earlier results and to accommodate the mouth’s continuing growth. At some point the treatment focus shifts to cosmetic enhancement (which can include implants, crown or bridgework) and periodontal health, to ensure gum tissues that support teeth and gums aren’t compromised by the effects of the cleft or its treatment.
At the end of this long process, something of a miracle may seem to occur: a young person’s once disfigured mouth transforms into a beautiful smile. It’s a chance for them to gain a normal life — and a new lease on physical, emotional and oral health.
