Types of Clefts Of The Lip And Palate

Overview Clefts Of The Lip And Palate

Each year approximately 227,500 or 7 percent of births in the United States are affected by birth defects of the head and face. The most common of these are clefts of the lip and palate which occur once in every 700 births. Clefts occur in infants of all races with a 2:1 male to female ratio. The incidence of clefts is highest in the Asian population and lowest in African Americans. Of all orofacial clefts, 21 percent present as cleft lip only (unilateral and bilateral), 46 percent present as cleft lip and palate, while the remaining 33 percent have cleft palate alone.

What Is A Cleft?

A cleft is a division or separation of parts of the lip or roof of the mouth that is formed during the early months of development of the unborn child. All of the parts of the lip or roof of the mouth are present; they simply failed to fuse in a normal way. Surgical intervention is necessary to align the parts and join them. Often the bones of upper jaw (maxilla) and/or the upper gum are affected. A cleft lip can be incomplete with a variable degree of notching of the lip, or complete, extending through the lip and into the nose.

Clefts of the palate can vary in severity. Some may involve just the uvula and the soft palate. These are incomplete clefts of the palate. Others extend the length of the palate and are complete clefts. They may involve one side of the palate (unilateral) or both sides (bilateral).

Etiology:

The exact cause of lip and palatal clefting is not known, but most experts feel that it is due to both genetic and environmental factors. Clefts are associated with abnormalities in the genes which may be a result of inheritance or from a spontaneous mutation during fetal development. We recommend genetic counseling to discuss causes of the cleft and the recurrence risk factors.

Team Assessment:

Children born with clefts should be carefully assessed by the craniofacial team in order to detect potentially serious abnormalities that can be associated with clefting. There are over 150 syndromes that include cleft lip or palate in their differential diagnosis. Generally, clefting is the only congenital abnormality that the child has, but nearly 15 percent of all cleft lip or palate patients present clinically with multiple problems.

 

The team concept allows a systematic, comprehensive treatment plan to be developed and allows the team members to work together to identify problems before they become significant. The most common specialties involved in the care of a child with a cleft are plastic surgery, otolaryngology, dentistry, audiology, speech pathology, genetics, and pediatrics. Once a complete assessment of the child with the cleft has been performed, a plan for treatment can be outlined.
