Craniosynostosis: Premature fusion of the sutures between the growth plates in an infant's skull that prevents normal skull expansion. Craniosynostosis (from cranio meaning skull, syn meaning together, and ostosis relating to bone) is a condition in which an infant’s skull bones prematurely fuse, thereby changing the growth and shape of the skull. Unilateral coronal craniosynostosis is present when one coronal suture closes before growth of the brain and skull are complete. Related Articles Note restricted growth and asymmetry on the right side of the head and how the child’s right eye socket appears taller than the left and that the bridge of the nose is … Surgery for craniosynostosis has evolved rapidly over the past two decades, with increased emphasis on early, extensive operations. Studies Linking Autism and Craniosynostosis. Craniosynostosis is a birth defect in which one or more sutures on a baby's head closes earlier than usual. Research shows that the incidence of some degree of plagiocephaly in infants is almost as high as 50%, of which approximately 4% are severe. When two or more sutures are fused, there is a greater risk of pressure on the brain. The deformity varies significantly depending on the suture or sutures involved. Children with Suspected Craniosynostosis: A Cost-Effectiveness Analysis of Diagnostic Strategies L. Santiago Medina , Randy R. Richardson , Kerry Crone American Journal of Roentgenology . Diffuse, severe beaten-copper pattern is an indicator of chronic elevated intracranial pressure, which is more common in patients with craniosynostosis. Premature closure of all the sutures can cause microcephaly (an abnormally small head), which prevents the normal growth of the brain and results in mental retardation. A similar risk exists for children of parents with craniosynostosis. It may result from a primary defect of ossification (primary craniosynostosis) or, more commonly, from a failure of brain growth (secondary craniosynostosis). As nouns the difference between craniosynostosis and synostosis is that craniosynostosis is (pathology) a medical condition in which some or all of the sutures in the skull of an infant close too early, causing problems with normal brain and skull growth while synostosis is (medicine) the abnormal development of a joint. 2002;179:215-221. Is my baby's head a normal shape? Methods . Sagittal craniosynostosis, also called scaphocephaly or dolichocephaly, is the most common type of craniosynostosis, which occurs when bones in an infant’s head fuse together abnormally.The experienced doctors at St. Louis Children’s Hospital have been treating scaphocephaly for decades. Craniostenosis 1. There is a 0-4% chance that a sibling born after a child with craniosynostosis will also have the condition. Craniosynostosis can cause an abnormally shaped skull. Surgery can correct it. Craniosynostosis is a rare condition in which an infant has an abnormally shaped skull after the cranial sutures fusing too early. Mark Proctor, MD - Chief, Department of Neurosurgery. Craniosynostosis is the premature and abnormal fusion of 1 of the 6 suture lines that form the living skull (see the images below). While this procedure often has cosmetic benefits, these are considered secondary to the need to create extra space for the growing brain. The skull then attempts to grow parallel to the fused suture, rather than perpendicular to it, causing an abnormal head shape. The sutures allow for growth of the skull. Diagnosis of craniosynostosis may include: Physical exam. In craniosynostosis, one or more of the sutures close early.

It produces an abnormally shaped head and, at times, appearance of the face. Three-dimensional computed tomography (CT) has an important role in determining the presence and extent of congenital and acquired craniofacial deformities. First described by Virchow in 1851, craniosynostosis affects approximately one infant in every 2000 2. Craniosynostosis occurs in about 1 out of every 2,500 newborn babies. Even with surgery, it can cause a variety of behavioral and learning challenges.
