Torticollis and Plagiocephaly

What is Congenital Muscular Torticollis (CMT)?

CMT is a condition detected in infants at birth or shortly after.  The infant will usually present with their head rotated and/or tilted to one side. This happens due to the shortening or tightening of the neck muscles, most commonly the sternocleidomastoid (SCM) muscle. The most common reason why your child’s neck muscle has tightened is usually due to the way your baby was positioned in the womb before birth. Torticollis will limit your child’s ability to move their head in the full range of movement, and this may affect their ability to interact freely with the environment.

What is Plagiocephaly?

Torticollis can also be associated with the flattening of the back of your child’s head. This is known as plagiocephaly. With torticollis, the baby’s head is usually rotated to one direction. This causes repeated pressure on one part of the head. Plagiocephaly can also be caused by sleeping regularly in one position only, causing the infant’s soft skull to be flattened in that area.

Not sure yet whether what you are seeing needs a look? Our guide to a baby leaning their head to one side explains how to tell a favourite side from a tight neck muscle, what you can safely do at home, and when to come in.
