Clinical Notes

The palatine bones contribute to the hard palate, the floor and lateral wall of the nose, and the floor of the orbit. Cleft palate results from failure of the palatal shelves (derived from the palatine bones and maxillae) to fuse in the midline at week 12 of development. Palatine bone involvement in Le Fort II and III fractures requires surgical reduction.
