More Information on Suture Closure
The metopic suture begins at the nose and continues to meet the sagittal suture. Metopic craniosynostosis results in a narrow, triangular forehead with pinching of the temples laterally(trigonocephaly).
The Metopic Suture is the first and only suture which normally fuses early in childhood(normally around 6 to 8 mths but in some cases as early as 3 months.) Metopic Craniosynostosis is one of the least common forms of Craniosynostosis. However, sometimes the early fusion of the Metopic suture will cause a Metopic ridge with no trigonocephaly. In cases of a metopic ridge surgical intervention may not be needed.
In true Metopic Craniosynostosis with the evidence of trigonocephaly (a triangular forehead and narrowing to the skull), whether this narrowing is mild or severe, many experienced surgeons will recommend that the infant's skull should be surgically repaired.
If your child has a Metopic ridging with no trigonocephaly be sure to consult a craniofacial specialist. Even if you are advised to be wait and see always research and ask questions.
Even with these thoughts on Saggital Craniosynostosis there is nothing that an expectant mother can do to prevent craniosynostosis. There is still not enough known about Saggital and any other form of Craniosynostosis. Research is still being discovered for the causes of premature suture closure.
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 that is known as
Unilateral (left or right) Coronal synostosis
The shape of the head is sometimes referred to as plagiocephaly (which should not be confused with positional plagiocephaly.) The forehead on the effected side is flattened and swept back with the eye in its socket. Unilateral Cranio can give the appearance that one eye is wider open then the other which is caused by the lack of orbit around the affected eye.
Lambdoid Craniosynostosis is the rarest form of Craniosynostosis and fusion of both Lambdoid sutures is more rare. The diagnosis of Lambdoid synostosis is the most difficult to make because on plain skull x-rays the lambdoid suture is frequently misdiagnosed as being fused shut. Ideally, the diagnosis of lambdoid synostosis is made by CT scans, read at an experienced center. Children who have lambdoid synostosis and significant flattening.
How is Craniosynostosis Fixed?
There is no cure for Craniosynostosis.
The only treatment is surgery.
Parents that suspect something wrong with their child's head shape should consult with a pediatric craniofacial surgeon and/or pediatric neurosurgeon.
The main purpose for surgery is to open up the skull to allow proper skull growth as well as to correct the shape of the skull. As more of our children are affected with Craniosynostosis research is being done on the impact fused sutures might have on brain function. Some of our children might have cognitive delays while others will grow up with no affects from the synostosis and surgery. This is a scary time for parents of children with craniosynostosis. It opens up a whole roller coaster of emotion. There are groups that will help you face prediagnosis concerns, surgery, and postop care CAPPSKids.org and CranioKids.org as well as the JorgePosada Foundation strive to help families affected with Craniosynostosis. Their links and info are provided on our support page.
