Extractions: CRANIOSYNOSTOSIS What is craniofacial surgery? Craniofacial surgery is a surgical subspecialty developed by Paul Tessier thirty years ago in France. It involves surgery of the skull and face for tumors, trauma, and congenital deformities. For many years, the severity of these conditions was thought too risky for surgical intervention. Tessier, a surgeon himself, challenged this belief and began building the foundation of craniofacial surgery. In doing so, he recognized that this complex form of surgery could only be performed by a specially trained surgeon who was supported by a highly skilled team. The surgical team at Hermann Children's Hospital includes a pediatric neurosurgeon and craniofacial surgeon as well as a specialized anesthesiologist. The neurosurgeon works on the skull and the craniofacial surgeon on the face. With both areas being closely related the combined approach offers the best possible results with the highest level of safety. What is craniosynostosis? Diagram of skull, showing location of fontanelles and sutures The skull of an infant is made up of free-floating bones separated by fibers called sutures. This arrangement allows the infant's head to pass through the birth canal and also enables the skull to grow with the brain in early infancy.

Extractions: Thursday, 1 April Age of Referral in Sagittal Synostosis Implications for Management Mr C Duncan, Mr A Gibbons, Mr I Sharpe, Mr A Monaghan, Mr H Nishikawa, Mr G Solanki, Mr MS Dover. Sagittal synostosis which presents as scaphocephally has an incidence of 1 in 4000 births and is the most common craniosynotosis. Traditional management involves a strip craniectomy performed at 6 months of age however recent data has questioned the efficacy of this regime and suggests that earlier treatment is required in order to achieve a normal cephalic index when calvarial growth is completed. Surgical management of patients with scaphocephally older than 12 months requires calvarial remodelling and a normal cephalic index is rarely achieved. The aim of this study was to determine the percentage of patients presenting to our unit with sagittal synostosis at an age at which optimum treatment could be offered. A retrospective review of 28 patients referred to our unit with scaphocephally showed that 50% were seen at a median age of 7 months while the remainder were seen at a median age of 23 months. A prospective study of new patient referrals with scaphocephally conducted over 1 year confirmed this pattern with 50% of patients seen for the first time at a median age of 13 months. In conclusion, most patients with sagittal synostosis present too late for simple treatment. The implications and possible solutions will be discussed.
Extractions: 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. If surgery is required, the members of the department are skilled in the various surgical techniques used for remodeling and reconstruction of the skull. Even the most complex cranio-facial surgeries are routinely undertaken, taking advantage of our experienced surgical and post-surgical teams, including the pediatric neuro-anesthesiologists and pediatric intensive care unit staff. Our surgeons work in conjunction with the plastic surgeons of the St. Louis Children's Hospital Craniofacial Team on cases of severe malformations of the face and skull and those associated with other syndromes (such as Apert's and Crouzon's syndromes).

Reported incidence varies from 3-5 per 10,000 (Cohen, 1986) to as high as 10 per 10,000 (French et al., 1990). These discrepancies may be due to different methods of ascertainment, i.e., surgical (Lammer et al., 1997) vs. medical cases, or may result from different diagnostic criteria used to differentiate between isolated and syndromic cases. Prospective analysis of 29,235 births in a single hospital identified 18 cases over an 8 year period, yielding a birth prevalence of 6 per 10,000 for isolated non-syndromic cases (Shuper et al., 1985). Epidemiologic study conducted in Western Australia between 1980-1994 documented prevalence of 5.02 per 10,000 births (Singer et al., 1999). Most commonly non-syndromic craniosynostosis occur sporadically. About 8-10% of coronal synostosis patients have a positive family history of the disorder, but only about 2% of sagittal synostosis present as familial forms (Hunter and Rudd, 1976; 1977; Shuper et al., 1985). However, some of the patients with coronal synostosis may have been misdiagnosed as non-syndromic, due to the extreme variability of some Mendelian syndromes.

Extractions: Home Premature ossification of a suture, or synostosis, is sometimes attributed to intrauterine restraint of head growth by twinning or by early engagement of the head in the pelvis. It is commonly seen in craniofacial disorders such as Crouzon, Apert, Pfeiffer, or Saethrre-Chotzen syndromes, or in the setting of fetal exposure to phenytoin, valproic acid, or other teratogens. Most often, however, there is no identifiable cause. Sporadic cases typically involve a single suture; syndromic cases typically demonstrate more complex, multi-sutural involvement, often bilateral coronal synostosis. The expansion of the head is driven from within by growth of the brain, and craniosynostosis causes deformity by restricting expansion of the head in the dimension perpendicular to the affected suture. Compensatory pressure by the growing brain results in expansion, or bossing, in adjacent areas of the skull. The characteristic patterns of deformity caused by synostosis of each individual suture are readily recognized by the trained eye. Thus, physical examination is the gold standard for evaluation of this problem.

Extractions: helpful? yes no Abnormalities of skull shape can arise either from external pressure exerted on the head in early life, or from intrinsic abnormalities of growth. 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.
Craniofacial Surgery...David Herz, M.D. This is sagittal synostosis, where the suture along the top of the head closesprematurely. It produces an abnormally shaped head termed scaphocephaly. http://www.drherz.com/C_OurPractice/C33_Craniofacial.html
Extractions: Craniosynostosis? In this disorder, a child presents with a characteristic deformity of the head, or head and face. It is typically an intrauterine (inside the womb) event. This is probably due to a misdirected message from a gene. It is not due to a defect in parents. Sometimes, postnatal (after birth) synostosis can occur as well. There are rare cases where this is due to inborn errors of metabolism where the body chemicals affect bone growth abnormally.

Extractions: CRANIOSYNOSTOSIS Craniosynostosis is a condition that children are either born with or develop. It literally means fusion of the skull bones and may occur singularly or as part of a genetic syndrome. At birth, the human skull is not a solid mass of bone. Rather, soft spots or sutures separate the seven bones that comprise the skull. These separations allow for brain growth. When one or more of these sutures close prematurely, the result is called a craniosynostosis condition. The deformity that results depends on which suture(s) is involved. What actually happens is that as a baby grows, the brain increases rapidly in size. When the suture(s) fuse, there is no room for the brain to develop at that area. This growth inhibition is compensated for by overgrowth in another area resulting in an abnormally shaped skull. Types of Craniosynostosis (a) Isolated craniosynostosis is non-inherited and usually involves only one suture. Sagittal synostosis refers to premature closing of the midline suture that runs from front to back of the skull. This results in an elongated and narrow skull shape called scaphocephaly Metopic synostosis refers to the early closing of the forehead suture.
