(a) 3D ultrasound image of a normal fetus at 20 weeks. The baby develops a noticeable ridge extending along the center of her forehead. How to cite this article: StamatianF,Kovacs T,MilitaruM, CaracosteaG.ApertSyndromeintheEraofPrenatalDiagnosis. Donald School J Ultrasound Obstet Gynecol 2014;8(2):222-225. The metopic suture—the joint that runs from the baby’s fontanel (the “soft spot” at the top of the head) down the forehead to the top of her nose—closes too early. Craniosynostosis was suspected on the basis of skull deformities when present, however the diagnosis was only c d a b Figure 2 Lateral view of the fetal skull showing calvarial sutures. Prenatal ultrasound images of 19 patients with postnatally diagnosed metopic or coronal suture craniosynostosis were retrospectively reviewed. RESULTS: It was not possible to diagnose craniosynostosis in the first trimester. A retrospective study including 618 cases of isolated craniosynostosis revealed that only 2 cases (0.3%) were known to have been diagnosed prenatally [16]. coronal craniosynostosis; metopic synostosis; lambdoid synostosis; It is possible to have just one type or a combination of them. A two-month-old male baby presented with cranial dysmorphism, which had been present since birth. Lambdoid. Diagnosis of craniosynostosis may include: Physical exam. Currently, the interest on craniosynostosis in the clinical practice is raised by their increased frequency and their genetic implications other than by the still existing search of less invasive surgical techniques. Rea D, Ryan S Connected authors. Metopic craniosynostosis is commonly characterized by the triad of a keel-shaped forehead (trigonocephaly), biparietal widening, and hypertelorism. Rozovsky K, Udjus K, Wilson N, et al. Tartaglia M, Bordoni V, Velardi F, et al. metopic to the sagittal sutures. Case Type. Her eyes may be spaced too closely together. is characterized by coronal craniosynostosis, frontal bossing, midfacial hypoplasia and symmetric syndactyly of the hands and feet4,5. Regarding preoperative surgical planning in our institution, 3D-CT examination was only performed in cases of metopic, coronal or complex craniosynostosis. Craniosynostosis is defined as the premature closure of the calvarial sutures. B, Ultrasound image showed … Cranial Ultrasound as a First-Line Imaging Examination for Craniosynostosis. The cause of the premature fusion also differentiates the major types of craniosynostosis. Cranial Ultrasound as a First-Line Imaging Examination for Craniosynostosis. Prenatal ultrasound`s detection rate of craniosynostosis is low. He had surgery around 5 months and is now doing helmet therapy. Although Reports on prenatal ultrasound examination of cranial sutures are relatively rare in the literature [2,11-13]and the detection rates of craniosynostosis are low [14,15]. My baby was born on 2/3 and diagnosed with metopic craniosynostosis shortly after he was born. 3) Metopic or trigonocephaly craniosynostosis, is when the metopic suture runs from the top of the bridge of the nose through the mid-line of the forehead to the soft spot. Summary. (b) 3D ultrasound image in a 20‐week fetus later diagnosed with Pfeiffer syndrome. Imaging studies. Most affected infants are asymptomatic; CS is usually recognized based on an abnormal head shape in the first year of life. Metopic synostosis – The metopic suture runs from the baby’s nose to the sagittal suture at the top of the head. Although the majority are sporadic, Craniosynostosis syndromes may be associated with environmental and genetic factors. Clinical History. Lateral frontal retrusion or pinching can also point to this disorder. This includes measuring your child’s skull. 2 months, male Download as PDF Print Show related cases Notify admin. Perhaps because of the peculiar shape of the skull, this condition has been classified by several authors with the various types of premature closure of the cranial sutures (3), being ascribed to intrauterine closure of the metopic suture. If this suture closes too early, the top of the baby’s head shape may look triangular, meaning narrow in the front and broad in the back (trigonocephaly). Keywords: Nasal glioma, Trigonocephaly, Fetal MRI. Craniosynostosis is defined as a premature fusion or one of more cranial sutures during intrauterine or postnatal development. This is one of the rarest types of craniosynostosis. This is also called trigonocephaly. Eight children (6.3%) had craniosynostosis of one suture (five sagittal, two metopic, and one coronal) on x-rays and ultrasound. A 5-month-old girl with metopic craniosynostosis. This case is the first reported case of nasal glioma in association with craniosynostosis in the published literature. Patient. Pediatrics 2016; 137:e20152230. Her forehead will look overly narrow. Metopic craniosynostosis seems to affect more males than females but we are not yet sure why this should be the case. This was confirmed at autopsy. Clinical Cases Authors. Paediatric radiology . US demonstrated diagnosis of craniosynostosis in an initial step and then allowed us to wait for the right moment to perform 3D-CT (one month before surgery). Metopic. Institutional review board approval and parental informed consent were obtained. ... Children aged 0 to 12 months who were assessed for craniosynostosis during 2011-2013 by using 4-view skull radiography and CUS of the sagittal, coronal, lambdoid, and metopic sutures were included in this prospective study. This can result in a protruding ridge forming along the middle of the forehead. Craniosynostosis may be present at birth (congenital). Fetal craniosynostosis can be diagnosed through ultrasound (sonogram) when an asymmetry or bulge in the skull appears. He is 6 months and will hopefully be done with his helmet when he’s 1. Although it can be diagnosed through ultrasound, it may be difficult to detect. Craniosynostosis is a condition in which premature fusion of the bony plates of the skull leads to abnormal head shape and the potential for complications such as raised ICP. If it is found, it is usually not discovered until the third trimester. Methods: Children aged 0 to 12 months who were assessed for craniosynostosis during 2011-2013 by using 4-view skull radiography and CUS of the sagittal, coronal, lambdoid, and metopic sutures were included in this prospective study. The transducer was then turned 90 degrees to explore the coronal and lambdoid sutures. Metopic craniosynostosis (Trigonocephaly) Section. You may be asked if you have a family history of head or face defects. Keywords: Apert syndrome, Craniosynostosis, Syndactyly, Metopic suture. Childs Nerv Syst 1999; 15:389. The third most common type of craniosynostosis is called metopic synostosis, which occurs when the frontal bones fuse along the metopic suture. Rea. It may present either as an isolated entity sporadically (70%) or may be associated with other abnormalities as part of a syndrome. Ultrasound simulator for craniosynostosis screening . The 26 ultrasound examinations obtained were compared with normal images and tables of gestation. Furthermore, we considered that a child with a characteristic … CASE REPORT. Fibroblast growth factor receptor mutational screening in newborns affected by metopic synostosis. Abstract: An ultrasound simulator to train radiologists and technologists to locate and recognize patent and fused cranial sutures. Metopic craniosynostosis can occur as an isolated abnormality or in association with multiple syndromes. Premature fusion gives the forehead a triangular appearance and widens the back part of the head. Several studies have shown the effectiveness of ultrasound (US) in craniosynostosis, but it is not used for routine screening in many centers, as this depends on the preferences of referring physicians. There was 100% reader agreement for sagittal, coronal, and lambdoid sutures, but three metopic sutures were interpreted differently on ultrasound versus radiography. The 26 ultrasound examinations obtained were compared with normal images and tables of gestation. In two of these studies, the Child Behavior Checklist (CBCL) was given to children with SSC in hospital-based craniofacial programs. The last ultrasound I had was 20 weeks and it was normal. Craniosynostosis (CS) is the premature fusion of one or more cranial sutures.It is caused by a mutation in genes that code for fibroblast growth factor. Craniosynostosis refers to the premature fusion or ossification of the cranial sutures and can occur from genetic etiologies, as well as from some metabolic disorders and mechanical changes, such as in a child with shunted hydrocephalus.With premature closure of a suture or sutures, relatively predictable head shapes and facial distortion occurs. METHOD: Prenatal ultrasound images of 19 patients with postnatally diagnosed metopic or coronal suture craniosynostosis were retrospectively reviewed. Imaging Findings. We aimed to compare the accuracy of cranial ultrasound (CUS) with radiography for the diagnosis or exclusion of craniosynostosis. Straight lateral frontal bones and narrow orbits with upsloping superior orbital rims are also suggestive of metopic synostosis. A, Three-dimensional CT con rmed abnormal . The model is formed, for example, using specially fabricated heads or from life-sized plastic doll heads. Craniosynostosis requires evaluation by specialists, such as a pediatric neurosurgeon or a specialist in plastic and reconstructive surgery. United States Patent 7731499 . closure of the metopic suture. Imaging Findings. The metopic, coronal and anterior sagittal sutures are clearly patent and well‐demonstrated. a, anterior fontanelle; b, pterion; c, frontal bone; d, coronal suture. All newborns with Apert syndrome have coronal synostosis and a widely patent midline calvarial defect extending from the glabella to the posterior fontanelle6. Trigonocephaly is an obvious, relatively uncommon deformity of the skull characterized by a triangular, pointed, frontal bone. The metopic and coronal sutures are fused in keeping with global craniosynostosis. Or it may be found later, during a physical exam. This premature fusion will give a triangular shape to the forehead and widens the back part of the baby’s head. The metopic suture runs from the top of the bridge of the nose up through the midline of the forehead to the anterior fontanel and the sagittal suture. The diagnosis is based on a physical exam. Your doctor will feel your baby's head for abnormalities such as suture ridges, and look for facial deformities. The main method of treatment is surgical and has anaesthetic concerns associated with surgery in young children with the specific risks related to blood loss and VAE. 5, 6 The third study relied on parent report to assess behavioral problems among 63 children with metopic craniosynostosis evaluated over a 10 year period. The number of babies born with metopic craniosynostosis also seems to be increasing but again, more research is needed to discover the reason for this increase. These reasons, together with the problem of legal issues, make the need of a definite diagnosis for a crucial problem, even in single-suture craniosynostosis (SSC). If your baby has this it will be way harder for you than for your baby. Lateral frontal retrusion or pinching can also point to this disorder. During the exam, your child’s healthcare provider will ask a lot of questions about your pregnancy and your child’s birth. In the second trimester, Kleeblattschädel was diagnosed at … Straight lateral frontal bones and narrow orbits with upsloping superior orbital rims are also suggestive of metopic synostosis.
