Cleft lip (a separation in the upper lip) and cleft palate (a split in the roof of the mouth) are the most common types of conditions that affect the skull and face.

Craniosynostosis occurs when one or more of the joints in a baby’s skull closes too early. The condition is sometimes noticeable at birth, but it also can be diagnosed as infants grow and develop.

Deformational plagiocephaly, also called “flat head syndrome,” is a condition in which a baby’s head has an uneven or irregular shape caused by external forces.
