Living with Non-syndromic metopic craniosynostosis

A condition in which the seam at the front of a baby's skull closes too early, changing the shape of the forehead.

Understanding Non-syndromic metopic craniosynostosis

Non-syndromic metopic craniosynostosis is a condition in which the metopic suture, the seam at the front of the skull, closes too early.

It is a form of craniosynostosis that is not part of a larger syndrome. The early closing can give the skull a triangular shape and a narrow forehead, with a prominent brow and eyes set close together. GARD lists newborn and infant years as the usual onset.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Early closing of the metopic suture
  • Triangular skull shape (trigonocephaly)
  • Narrow forehead
  • Prominent brow
  • Eyes set close together (hypotelorism)
  • Wide nasal bridge

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists, eye disease specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    World Craniofacial Foundation may keep lists of experts for this condition.
