There are about five sutures in the cranium namely sagittal, coronal, metopic, lambdoid and squamosal (see Figure 1 and Figure 2). craniofacial anomalies archive at St. Louis Children's Hospital: 20 years of craniofacial.

Metopic suture The second most common fusion occurs in the metopic suture. This runs up the middle of the forehead and when fused, may cause an angled forehead with a crest pointed area in the middle of the forehead and a swept back appearance to the eyebrow and temple bones.
The eyes may also appear close together. This head shape is known as trigonocephaly. There are varying degrees of deformity in trigonocephaly. Severe and obvious cases will require surgery, while mild cases may need no surgery or limited surgery at a later date.
Craniosynostosis fact sheet
Coronal suture The coronal suture runs from the top of the skull down the sides towards the corner of the eye. There is a coronal suture on both sides of the skull.
One or both sutures can become fused and this results in a flat forehead and a difference in the appearance of the eyes, with one being more open than the other. Lambdoid suture The lambdoid suture is at the back of the skull.
This fusion is rare and requires surgical correction. If the lambdoid suture fuses, it causes flattening to the back part of the skull.
This is different to deformational plagiocephaly. Will craniosynostosis cause problems for my child?
Most single suture fusions do not result in pressure on the growing brain. However, a small percentage of children may have developmental problems if the condition is not corrected with surgery when they are young. There is no way to predict which children may be affected in this way.
Although neurological damage can occur in severe cases of craniosynostosis, most children have normal cognitive development and achieve good cosmetic results after surgery. How is craniosynostosis treated? When two or more sutures are fused, there is a greater risk of pressure on the brain. In these situations, surgery is needed for cosmetic purposes and to allow enough room for brain growth.
By age thirty-five, the suture is completely closed.
- Sagittal suture
This means that when inspecting a human skull, if the suture is still open, one can assume an age of less than twenty-nine. Conversely, if the suture is completely formed, one can assume an age of greater than thirty-five. The bregma is formed by the intersection of the sagittal and coronal sutures.
The vertex is the highest point on the skull and is often near the midpoint of the sagittal suture. At birth, the bones of the skull do not meet.
Sagittal suture - Wikipedia
If certain bones of the skull grow too fast then "premature closure" of the sutures may occur. This can result in skull deformities.
If the sagittal suture closes early the skull becomes long, narrow, and wedge-shaped, a condition called scaphocephaly.
