Cranial Asymmetry

Understanding skull related symptoms and features.

Symptoms may affect multiple parts of the body. Understanding which part of the body a symptom affects, can help us to better understand the potential underlying causes of a symptom, including a rare disease or genetic syndrome.

The skull has several crucial functions: it cradles and protects the brain, supports the face and forms the head. It is a bony structure made up of the mandible and cranium.

Symptoms affecting the skull can sometimes be seen with the naked eye, especially if they affect the shape, size and structure of the head and face. Diagnosing a skull related symptom may involve different tests and assessments, both subjective and objective.

What is Cranial asymmetry?

Cranial asymmetry is when the bones of the skull are not symmetrical or even on both sides. It can give the appearance of a flattened side of the skull. It occurs usually on the back of the skull, or on one side.

It is something that is considered quite common in newborns, who are born with very soft skull bones (these fuse and harden over the course of their first few years of life). In a newborn this cranial asymmetry can be caused by pressure on the skull bones during delivery. In other newborns it occurs in those who favor one side of the head to sleep on, over another.

What should I do next?

In some instances, cranial asymmetry may be one of the features of a rare disease or genetic syndrome. In this case fast, targeted genetic analysis can give you a more accurate diagnosis.

"Our road to a rare disease diagnosis was a 5-year journey that I can only describe as trying to take a road trip with no map. We didn’t know our starting point. We didn’t know our destination. Now we have hope."
