neuro kraniosynostos

Sovläge kan skapa assymetrisk lambdoid sutur - occipital plagiocefali kan bero på både synostos och Non Synostotic occipital plagiocephaly (NSOP)

NSOP ger bland annat en öppen sutur med orientering tvärgående mot kalvariet, örat är oftare felställt när man tittar uppifrån, endast inre heaping (25% har fokala fusioner). LC -lambdoid craniosynostos visar istället mastoid och parietal bossing och både inre och yttre heaping.

metopic synostosis

The metopic suture begins at the nose and continues superiorly to meet the sagittal suture. 

Metopic craniosynostosis results in a narrow, triangular forehead with pinching of the temples laterally. 

Treatment involves releasing the suture and expanding and rounding out the upper face, forehead and skull.

coronal synostosis

The coronal sutures begin at the ear and continue superiorly to the top of the skull to meet the sagittal suture.

One or both sutures may be involved. When one suture is fused, the forehead on that side is flattened and swept back with the eye in its socket.

When both sides are fused, the head is short and wide with bulging of the eyes and bulging of the skull around the ears.

The surgical correction depends on whether one or both sutures are involved. When one suture is fused, it is removed and the forehead and brow reshaped and brought forward to match the other side. 

In addition, the cheek is also brought forward to reposition the eye socket. When both sutures are fused, they are both removed and the skull is narrowed and lengthened.

In addition, both cheekbones are brought forward to reposition the eye socket.

sagittal synostosis

The sagittal suture runs from a spot at the front of the head to the back of the skulI. Fusion of the suture results in a long, narrow skull with or without bulging of both the front and back of the head.

 Surgery of sagittal craniosynostosis involves removing the suture and widening the skull by opening up the coronal and lambdoid sutures on both sides of the head. 

Sometimes bone grafts are placed to keep the out-fractured bones apart.
