Congenital Malformations of the Oral Cavity

Congenital malformations of the oral cavity may involve the lips, jaws, hard palate, floor of mouth, and anterior two thirds of the tongue. These malformations may be the product of errors in embryogenesis or the result of intrauterine events disturbing embryonic and fetal growth. This article begins with a review of the pertinent embryologic development of these structures. After reviewing the normal embryology, specific malformations are described. Recommended management follows the brief description of each malformation. An attempt is made to point out where these malformations deviate from normal development. Finally, management recommendations are based on traditional methods and recent advances described in the literature.
