Chapter 302 Cleft Lip and Palate

Clefts of the lip and palate are distinct entities closely related embryologically, functionally, and genetically. Although there are a variety of theories, it is commonly thought that cleft of the lip appears because of hypoplasia of the mesenchymal layer, resulting in a failure of the medial nasal and maxillary processes to join. Cleft of the palate appears to represent failure of the palatal shelves to approximate or fuse.
