If one maxillary plate fails to unite with the naso-frontal in front, a cleft will be left through the upper lip on one side of the middle line, forming a single hare-lip. If both plates fail to unite a double hare-lip results, and the intermaxillary bone may be left adherent to the tip of the nose and septum nasi. If at the same time the development of the naso-frontal process is arrested, we get the rare condition of a wide gap in the middle line with absence of the incisor portion of the superior maxilla.

If both sides fail to unite completely the fissure is single behind and double in front, passing on each side of the intermaxillary hone.
