Craniofacial defects such as cleft lip and cleft palate are among the most common of all birth defects. They can occur as an isolated condition, or may be one component of an inherited disease or syndrome. The lifetime cost of treating the children born each year with cleft lip or cleft palate is estimated to be $697 million.
