uhrad.com - Neuroradiology Imaging Teaching Files Case Sixty Seven - Crouzon's Syndrome (Images # 1,2 and 3) Click on Images for Enlarged View Clinical History: None given. Findings: Image #1 is an axial CT which demonstrates increased biparietal diameter in relationship to the AP diameter. Image #2 demonstrates rather shallow orbits. Image #3 is a 3-D reconstructed CT image, which demonstrates the increased biparietal diameter and coronal synostosis. Diagnosis: Crouzon's Syndrome. (Coronal Synostosis) Discussion: Crouzon's syndrome is a craniofacial abnormality consisting primarily of coronal synostosis as well as sagittal synostosis (which incidentally is not seen in this case). In addition, patients with Crouzon's syndrome often have shallow orbits producing exophthalmos, as well as maxillary hypoplasia. The coronal synostosis produces a skull, which is widened in its biparietal dimensions, while the AP diameter is decreased. With sagittal synostosis, the opposite would be true, that is, the AP diameter would be increased while the biparietal diameter would be decreased. The synostosis can be demonstrated as a straight, rather than serrated radiolucent line. Alternatively, there may be frank ossification of the suture. In addition, to coronal synostosis and sagittal synostosis, patients with Crouzon's syndrome often have lambdoid synostosis. Other associated findings include calcification of the stylohyoid ligament and deviation of the nasal septum. Hydrocephalus may occur.

FIGURE 1. Sutures and fontanelles in the normal newborn skull. C ranial skeletogenesis is unique. The cranial skeleton is composed of an assortment of neural crest and mesoderm-derived cartilages and bones that have been highly modified during evolution. Cranial malformations, although uncommon, compromise not only function but also the mental well-being of the person. Recent advances in human genetics have increased our understanding of the ways particular gene perturbations produce cranial skeletal malformations. However, an abnormal head shape resulting from cranial malformations in infants continues to be a diagnostic and therapeutic challenge. Development The bones of the cranium are divided into the skull base and the calvarial vault. The growth of skull bones is driven primarily by the expanding growth of the brain. The brain grows rapidly in utero and during the first three years of life. An infant born at term has nearly 40 percent of his or her adult brain volume, and this increases to 80 percent by three years of age. Correspondingly, the size of the cranium of an infant born at term is 40 percent of adult size; by seven years, this increases to 90 percent.

Kane, MD The purpose of this review is to give an overview of craniosynostosis, targeted for the nonsurgeon, with emphasis on those aspects of craniosynostosis that could be of interest to the clinician treating deformational plagiocephaly. In particular, the orthotist could be involved in the treatment of both nonsynostotic deformational plagiocephaly and craniosynostosis by providing a cranial molding orthosis in both of these distinct clinical entities. The nomenclature applied in the description of these entities can lead to confusion with regard to diagnosis. Other articles in this themed issue describe in detail the treatment of deformational plagiocephaly. The focus here is on the epidemiology, pathogenesis, natural history, and surgical treatment of craniosynostosis. Differentiation of craniosynostosis from nonsynostotic deformational plagiocephaly is important, and methods to distinguish these entities are discussed as appropriate. CRANIOSYNOSTOSIS DEFINITIONS Authoritative definitions of key terms in this subject such as "suture" and "craniosynostosis" are elusive. Nevertheless, commonly used working definitions of these terms are available. "Suture" is used to describe a fibrous articulation between adjacent bones. "Craniosynostosis" in its common use denotes the premature closure of one or more sutures. This conception implies that a schedule of expected sutural closure exists and that each suture eventually closes.

Barringer, MS, CO Craniosynostosis is a cranial deformity that can be directly related to the premature closure of cranial sutures. It affects one in 2100 children, and of those, 40% to 60% are sagittal, 20% to 30% are coronal, and 10% are metopic. Lambdoid synostosis is the rarest. Researchers do not have a clear understanding of the genetic influences or developmental pathology that predisposes cranial sutures to premature closure. Treatment for craniosynostosis is reserved for surgical intervention. Many different types of surgical procedures have been described, including cranial vault reconstruction and endoscopic techniques. Although cranial orthoses are contraindicated for primary treatment of any variation of craniosynostosis, they can be a valuable adjunct to the postoperative management of many cases. The purpose of this discussion is to provide a review of pertinent literature concerning the use and role of postoperative orthoses. In addition, the results of a survey regarding postoperative orthotic treatment protocols are provided. LITERATURE REVIEW The different manifestations of craniosynostosis are commonly studied and reported; however, few authors have attempted to investigate the use of cranial orthoses after surgery. Many authors recommend the use of orthoses postsurgery to further enhance surgical correction, yet studies concerning the benefit of postoperative management are rare. A retrospective study at the University of Texas–Houston Medical School reviewed 21 children with sagittal craniosynostosis between 1994 and 2001.

Clinical Programs : Craniosynostosis Clinic During the first few years of life, the child's head is growing and changing. The skull, composed of the thin bones of the vault and the thicker bones at the cranial base, are adapting and accomodating the developing and expanding brain. This growth is quite rapid during the first 18 months of life, and continues for some years more. The growth and shape of the skull can be affected by many factors - some externally applied, some the result of problems with the brain, and some the result of direct abnormalities of the skull's development. The Department of Pediatric Neurosurgery is actively involved in the evaluation and treatment of the various abnormalities of skull growth and shape. These problems are diagnosed with a combination of clinical evaluation and radiographic imaging techniques . Many of the misshapen heads seen by our department are the result of positional plagiocephaly (deformation), and do not require surgical treatment. We have experienced orthotists available to assist in the molding helmet correction of these problems without surgery.

JUNE 1998 CONTENTS AUTHOR'S NOTEBOOK RELATED SITES A talented scientist and a devoted mother, Joan Richtsmeier was on top of the world. Then, against all odds, the parallel tracks of her life intersected, in a way she never could have expected. When Life Imitates Science By Melissa Hendricks Photos by Steven Rubin BEFORE EVERYTHING IN HER WORLD CHANGED, Joan Richtsmeier had been listening raptly to a speaker in a stately auditorium at the University of Chicago. It was the summer of 1994 and the finest minds in the field of vertebrate structure had come from all over the world to attend the conference. Richtsmeier, who had been invited to lead a workshop, was elated. At the workshop she planned to unveil to her international colleagues a new technique for measuring structure and growth. She had already used these methods to study skull growth in patients with severely disfigured faces and skulls, and hoped that the new tools would one day help refine surgical procedures for correcting such psychologically devastating conditions. There were other measures of success in her life. At age 38, Richtsmeier, a biological anthropologist, had already been named associate professor at the Johns Hopkins School of Medicine. She had recently published several articles in major research journals. Her students praised her in their written evaluations.

The most common intrinsic abnormality of skull growth is called craniosynostosis, which affects about 1 in 2,500 children. Craniosynostosis is the medical term for the premature closure of one or more of the seams between the skull bones. As the brain grows during fetal life and childhood, the overlying skull also enlarges by adding new bone at these seams, which are termed sutures. The major sutures are the midline metopic (at the front) and sagittal (at the top) sutures, and the paired coronal and lambdoid sutures. The coronal sutures run across the skull in front of the ears, crossing the junction of the metopic and sagittal sutures; the lambdoid sutures divide from the back end of the sagittal suture and run obliquely forwards to end up behind the each ear. The remaining 20 per cent of craniosynostosis is more complex and either involves the fusion of multiple sutures (5 per cent), and/or is combined with additional changes in the face, limbs or other parts of the body, indicating a 'syndrome' (15 per cent). Over 100 craniosynostosis syndromes have been described, most of which are extremely rare; the most common syndromes are Crouzon, Pfeiffer, Apert, Muenke, Saethre-Chotzen and craniofrontonasal syndromes. In these complex cases, there may be additional problems with the vision, breathing, hearing, teeth, learning development, facial appearance and malformation of the limbs and other organs.

Treatment Conditions and Diagnoses Craniosynostosis Related Services Neurosurgery Plastic Surgery What is craniosynostosis? Craniosynostosis, or simply synostosis, is the early growing together or fusion of two or more bones of the skull. A newborn's skull is made up of many separate bones that are not yet fused together. Because the brain grows quickly in the first two years of life, it is important that the skull bones not be fused yet. In fact, complete fusion of the bones normally occurs late in the teen years. Synostosis interferes with normal growth of the brain and skull. What is the cause of synostosis? Doctors haven't found all the causes for synostosis. In some case the cause appears to be genetic. What are the symptoms of synostosis? Craniosynostosis causes a change in the normal shape of the head. If a suture the seam between two skull bones is fused, it cannot grow, and the bones with open sutures then grow more than usual to allow enough room for brain growth. In many children the only symptom may be an irregularly shaped head. Some, however, will experience unusually high pressure on the brain, initially causing headaches. If left untreated, some children may then develop learning disabilities or problems with their eyesight. Early in life the brain is spared damage from this pressure by the other bones growing to accommodate the growing brain.
