Tests

At Boston Children’s Hospital, we know that the first step to treating your child’s metopic synostosis is to form a complete and accurate diagnosis.

How is metopic synostosis diagnosed?
Children with metopic synostosis usually display visible symptoms at birth, namely:

  • a ridge running down the forehead
  • a narrow, triangular shape to the forehead and top of the skull
  • sometimes, eyes that are spaced too closely together

Other times, a child’s metopic synostosis is diagnosed later in infancy during a routine physical examination.

Once an initial finding of metopic synostosis is made, your clinician may take the following steps to confirm the diagnosis:

  • obtaining a full family medical history
  • determining whether your child is experiencing any developmental delays or other problems in meeting age-appropriate milestones
  • measuring the circumference of your child’s head and plotting these measurements on a graph to detect unusual patterns
  • ordering a computed tomography (CT) scan, a non-invasive procedure using x-ray equipment and powerful computers to create detailed images of the skull

After we complete all necessary tests, our experts meet to review and discuss what they have learned about your child’s condition. Then we will talk with you and your family to outline the best treatment options.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
