Cranial deformities

A cranial deformity, such as plagiocephaly, is a skull deformation produced in the growing period by the mechanical pressure of any skull’s part before, during or after delivery.

he bones of the cranial vault and base of the fetus and the infant under three months are still poorly ossified and are separated from each other by sutures and fontanelles. If for any reason receive an excessive or continuous pressure, normal growth is interfered with and can cause deformations.

  • Cranial index A normal head has an oval shape seen from above and a normal ratio between width and length of 80%. This ratio enables us to quantify the degree of deformation.
  • Types of deformities: There are three basic patterns of craniofacial deformities which may affect infants in the first months of life: plagiocephaly, brachycephaly  and scaphocephaly. The best known is the plagiocephaly (flathead) and his name is sometimes used especially when talking in general of all.

Flattening in the back of the head, mostly on the right side.

Flattening of the back of the head, more or less symmetrical.

Transverse and elongated flattening, narrow and high head.
