Lambdoid Synostosis

What is Lambdoid Synostosis

Lambdoid craniosynostosis (also known as posterior plagiocephaly) is the rarest of the four types of craniosynostosis. If it occurs, though, it can lead to a flattening of the back of the head on whichever side is affected. It can also offset the growth of the mastoid process on the same side (ipsilateral mastoid bulge).

There are a number of signs that may indicate that the child is experiencing this condition. The ear on the affected side may be further back and toward the fused suture (though this is not always the case). It could also cause one side of the baby’s head to appear flat, one ear to be higher than the other, and the top of the head may tilt to one side.

How We Treat Lambdoid Synostosis

This condition can be treated through surgery. This procedure will help restructure the posterior fossa to create more space and allow for normal brain development. This procedure will also help restore the symmetry of the skull and maintain it throughout their development years.

Similar Conditions

Lambdoid craniosynostosis is rare enough that it is sometimes confused with posterior positional deformational plagiocephaly. It may also be associated with other forms of craniosynostosis, where more than one suture begins to fuse prematurely.

That is why the Cleft & Craniofacial Institute of Utah will carefully monitor and evaluate every case to make sure that your child is properly diagnosed and treated.
