The oral manifestations of 4p- syndrome

The oral manifestations of 80 reported cases of 4p- syndrome are analyzed and a new case is reported. Results indicate that the common pattern of cheilognathopharyngeal disorders in 4p- syndrome is an isolated cleft palate or a high-arched palate with micrognathia. Cases of cleft lip are only about 10% of the total. The significance of other reported aberrant phenomena cannot yet be estimated.
