Embryology & Early Development
Ossification
Ossification is the process by which tissue turns into bone, including the bones of the skull.
In short: Ossification
- Skull formation involves ossification.
- It continues after birth as the skull grows.
- It transforms precursor tissue into bone.
- Sutures and fontanelles allow the skull to grow during this process.
What it is
It is the process of forming bone from precursor tissue, including the bones of the skull. It begins before birth and continues as a child grows.
Understanding Ossification
Skull ossification continues after birth, which is why the infant skull has soft spots (fontanelles) and flexible joints (sutures) that allow growth. This ongoing process is part of why the young skull can heal and remodel well after surgery, and why reconstruction takes the child's age and growth into account.
Why it matters
Understanding ossification helps families see why the infant skull is still growing and flexible, and why this growth capacity is favorable for healing after encephalocele repair.
Common questions
What is ossification?
The process of forming bone.
Does it continue after birth?
Yes — the skull keeps growing.
Why does it matter for surgery?
The growing skull has a strong capacity to heal.
Bottom line
Ossification turns tissue into bone, and the skull continues to ossify and grow after birth.
