Neonatal Cranial Deformities: How to Recognize Plagiocephaly, Brachycephaly, and Scaphocephaly

Neonatal cranial malformations are deformities of the growing skull caused by mechanical pressure on certain parts before, during, or after birth.

Normal growth is hindered if, for any reason, the skull experiences excessive or continuous pressure, leading to the flattening of a part of the skull.

There are 3 types of craniofacial deformities that may potentially occur in newborns:

  • Plagiocephaly: when babies always sleep on the same side;
  • Brachycephaly: when they always sleep face up;
  • Scaphocephaly: when they sleep with their head always turned to one side.

Plagiocephaly is one of the cranial abnormalities classified as "dysmorphisms." Specifically, it refers to the deformation of a newborn's head during the first months of life. Plagiocephaly is a cranial deformity characterized by the flattening of the back of the head, usually on the right side, which can be accompanied by a forward shift of the same side of the head.

The forehead on the flattened side may be more pronounced, the eye on the same side may be more open, and the ear may be positioned further forward compared to the other side.

Top view:

  • The head is flattened on the back, either on the right or left side.
  • The ears are not aligned.

Side view

  • One ear is closer to the shoulder than the other.
  • One side of the head is more curved than the other.

Front view

  • One eye is smaller than the other.
  • One cheek is smaller than the other.
  • The top of the head is not flat
  • The height of the head is uneven
  • The mouth is not symmetrical

Bottom view:

  • The forehead is tilted
  • The face is tilted and appears deviated
  • The eyes and ears are not aligned
  • One cheek appears larger than the other

Positional Brachycephaly is a cranial deformity characterized by a more or less symmetrical flattening of the entire back of the head.

The heads of these children are shorter than normal and, to compensate, may appear wider when viewed from the front or taller when viewed from the side.

In some cases, it results in a virtually square-shaped head.

Top view:

  • The head is wider than it is long
  • The back of the head is flatter rather than curved

Side view

  • The head is shorter in the front than in the back; higher in the back
  • Flat posterior head

Front view

  • The face looks small compared to the head
  • The head is wide
  • The widest part is just above the ears
  • The tops of the ears protrude

Bottom view:

  • The head is wide
  • The widest part of the head is just above the ears
  • The forehead is flat, not rounded

Scaphocephaly is a cranial deformity characterized by a narrow, tall, and elongated head due to transverse flattening and elongation in the anteroposterior direction.

It occurs more frequently in premature and former premature babies.

It also affects children who sleep with a flat head on their side (temporo-parietal region).

Scaphocephaly can be either positional or the result of craniosynostosis due to the premature fusion of the sagittal suture of the skull.

Top view:

  • The head is long and narrow

Side view:

  • The head is longer in the front than in the back

Front view

  • The head is long and narrow
  • The forehead is elongated

Bottom view:

  • The head is narrow
  • The forehead is square

Premature babies are more likely to suffer from scaphocephaly due to the relative macrocephaly they present and the lack of tone in the cervical musculature.
