First of all there is physical exam. Doctors examine the baby's head for abnormalities such as suture ridges and look the facial deformities. Also, they utilizes Computerized Tomography which scan of the baby's skull. Fused sutures are identifiable by their absences. X-rays also may be used to measure precise dimensions of the baby's skull, using a technique called cephalometry. Genetic testing. If the doctor suspects the baby's misshapen skull is caused by an underlying hereditary syndrome, genetic testing may help identify the syndrome. Genetic tests usually require a blood sample. Depending on what type of abnormality is suspected, the doctor may take a sample of the baby's hair, skin or other tissue, such as cells from the inside of the cheek. The sample is sent to a lab for analysis. Rare types There are two less common types of<unk> s are: Metopic synostosis (trigonocephaly). The metopic suture runs from the baby's nose to the sagittal suture. Premature fusion gives the scalp a triangular appearance. Another one is Lambdoid synostosis (posterior plagiocephaly). This rare form of craniosynostosis involves the lambdoid suture, which runs across the skull near the back of the head. It may cause flattening of the baby's head on the affected side. A misshapen head doesn't always indicate craniosynostosis. For example, if the back of the baby's head appears flattened, it could be the result of birth trauma or the baby's spending too much time on his or her back. This condition is sometimes treated with a custom-fit helmet that helps mold the baby's head back into a normal position.
