Plagiocephaly - Flat Head Syndrome

- is a condition characterized by an asymmetrical distortion (flattening of one side) of the skull. It is also referred to as "Flat head Syndrome".

Plagiocephaly is the term that is used to describe a diagonal asymmetry across the head shape (see pic 1). This term particularly describes a flattening to one side at the back of the head; this often causes some facial asymmetry (see pic-2).

In the moderate to severe cases, there may be
  • Variations in the eyes alignment,
  • One eye appears larger than the other,
  • Ear displacement: The ear on the affected side may be pushed further forwards the front of the head compared to the other side,
  • One cheek appears fuller than the other.
  • The forehead on the affected side becomes more prominent.

What causes plagiocephaly (Flat Head Syndrome) ?


Prematurity - The syndrome is widely seen among new-born babies as they are often unable to turn their head in one direction due to neck pain. This causes the baby to prefer to be positioned on the same side of the skull. Constant pressure causes a flattening of the soft tissues in one spot compared the rest of the babies skull.

Intrauterine Environment Plagiocephaly is also found at birth and is the result of a restrictive intrauterine environment; this effect is particularly prevalent in premature babies.

Congenital Muscular Torticollis (Wryneck) - one or more of the neck muscles develops a tightness, causing the head to tilt and/or turn. This can result in plagiocephaly as the tightness causes the head to be held in a single position.

Infant Seat  - it has been noticed that extensive use of car seats, infant swings and bouncy seats also contribute to Plagiocephaly. In these devices, the back of the head is placed against a rigid, unyielding surface. The resulting deformity can be severe, even causing “cornering” or “squaring” of the head. While normal use is not a concern, extended use, especially allowing infants to sleep in them, increases the risk of Plagiocephaly.

Back-Sleeping Pressure - Since the ‘back to sleep’ campaign Doctors have recommended that all babies sleep on their backs to reduce the risk of Sudden Infant Death Syndrome (SIDS or ‘cot death’). Plagiocephaly has increased dramatically as the back sleeping position produces constant pressure on the rear of the skull. Plagiocephaly is directly related to baby’s sleeping behaviour.


Plagiocephaly is the most common form of this syndrome among young babies. There are different types of flat head syndrome as shown in the pictures below:

Mimos Baby Pillow helps young babies by preserving their head shape in a natural way without any other treatment. Unfortunately babies spend most of their time back-sleeping and will all develop a degree of head deformity, it is therefore important to protect your baby’s head at early stage. Early prevention plays a key role in preventing deformities of a baby’s head shape therefore Mimos UK recommend using the Mimos Baby Pillow from day one. Mimos is a safe baby pillow for crib/cot bed/moses basket/buggy/bouncer.




                                      For safety reasons all babies should back-sleep!

Mimos baby pillow is specially designed for Flat-head Syndrome (plagiocephaly) prevention and made from a special 3D polyester fiber composed of 94% air. This design allows babies to breath through the pillow. Therefore the Mimos pillow is reducing the risk of SIDS (Sudden Infant Death Syndrome).
