Metopic craniosynostosis occurs when the metopic suture fuses prematurely. Babies usually with this condition have an abnormally shaped head referred to as trigonocephaly. There is a ridge at the metopic suture, the forehead is angled instead of flat, like the front of a boat, and the eyebrow bones (supra-orbital rims) are pulled back.

One type of craniosynostosis is called metopic synostosis (also referred to as trigonocephaly or metopic suture craniosynostosis). A prominent ridge along the forehead by itself is often a normal finding, but children with metopic synostosis from premature fusing of the metopic suture have a triangular shape to the forehead.

Metopic ridging (MR) is treated nonsurgically while metopic craniosynostosis (MCS) is treated surgically. Differentiating between the two is paramount; however, consensus is lacking about where a clear diagnostic threshold lies.

2024年4月29日 · A metopic ridge is a prominent ridge running down your child's forehead. It is where suture lines meet between the two bony plates. A congenital defect called craniosynostosis, in which one or more sutures fuse prematurely, can cause a metopic ridge.

What is the difference between a benign metopic ridge and metopic craniosynostosis? A benign metopic ridge is a normal thing where the metopic suture in a baby's skull makes a ridge. It doesn't cause any problems.

2023年11月1日 · Metopic craniosynostosis is a birth defect that occurs when the two frontal bones in a fetus’ skull fuse too soon. This often occurs while a fetus is developing in the uterus, but can also occur shortly after birth. It results in a baby born …

2024年2月7日 · Metopic craniosynostosis occurs when your child’s metopic suture fuses prematurely. The metopic suture runs from the nose up to the sagittal suture on the top of the head. This condition causes a misshapen skull and head, which may affect brain growth.

Craniosynostosis refers to the premature closure of sutures of the skull and results in an abnormal head shape. It is a rare disorder with a prevalence of around 1 in 1500. Most cases occur already prenatally and will be diagnosed in the first few months of life.

The metopic suture is the only suture which normally closes during infancy. Upon closure, a palpable and visible ridge often forms which can be confused with metopic craniosynostosis. Benign Metopic ridging may be treated nonsurgically …

The main symptom of metopic craniosynostosis is the abnormal shape of the forehead which is pointed and triangular. There may also be a bone ridge over the prematurely-fused suture running down the forehead from the front fontanelle to the top of the nose.
