Just some facts...

This is the way the skull of a newborn should look....

This is what Logan's looks like...

Again, a normal skull....

you can see here the "ridge" that I talked about along to top of the skull!

Introduction

Sagittal suture craniosynostosis is a congenital condition in which the normal separation between the parietal bones has closed too early (synostosis). This separation is a suture line, and this suture line between the parietal bones is called the sagittal suture. The premature closure of this suture line is called sagittal synostosis and gives the condition named "scaphocephaly." There are other forms of craniosynostosis when other suture lines are involved. Scaphocephaly is the most common form of synostosis and it occurs in approximately 1 in 1000 newborns.

What Caused This?

In most situations it is caused by a disproportion in the size of the pelvis of the mother and the size of the fetal head, which creates a limitation of the growth of the fetal head in one direction and brings the two parietal bones together too early, creating the synostosis in the pelvis before birth. This is why it is most commonly seen with the first pregnancy. The fetus is usually a male, as males have larger heads than females. The association of these two elements is what favors the development of this condition. There is nothing that can prevent this condition from happening. Fortunately though, there is a treatment.
