PURPOSE: We propose an magnetic resonance imaging (MRI)-based quantitative morphovolumetric approach to the posterior cranial fossa (PCF) and craniocervical junction (CCJ) changes in achondroplastic patients investigating possible associations with ventriculomegaly and medullary compression. METHODS: We analyzed MRI of 13 achondroplastic children not treated by surgery. 3D FSPGR T1-weighted images were used to analyze (1) PCF synchondroses; (2) PCF volume (PCFV), PCF brain volume (PCFBV), PCFV/PCFBV ratio, cerebellar volume, cerebrospinal fluid (CSF) spaces volume, and IV ventricle volume; (3) PCF (clivus, supraocciput, exocciput lengths, tentorial angle) and CCJ (AP and LL diameters of foramen magnum (FM)) morphometry; (4) measurements of FM and jugular foramina (JF) areas; and (5) supratentorial ventricular volume...

INTRODUCTION: Atlantooccipital fusion or occipitalization of atlas or assimilation of atlas is a rare or uncommon abnormality recorded in anatomical, morphological and radiological studies. It is usually associated with reduction in dimensions of foramen magnum leading to acute or chronic neurovascular compression and clinical manifestations of varying severity. Though, atlantooccipital fusion is rare but it is important and significant for the physicians and surgeons for their diagnostic and therapeutic approach...

As a surgical method to treat children with sagittal craniosynostosis, calvarial vault reconstruction is subjected to some limitations. In traditional surgical method to treat children with sagittal craniosynostosis, surgical resection and fixation are performed all by the experience of surgical doctor, which is likely to cause individual differences, insecure fixation, configurational asymmetry, and waste of unnecessary fixtures materials. This study aims to provide surgical doctor with objective indicators via 3D simulation combined with biomechanical calculation, so as to improve the surgical efficiency...

BACKGROUND: The interfrontal angle (IFA) has been utilized as a surrogate for morphologic assessment of the anterior cranial region in metopic synostosis with success in characterizing presenting severity. Its utility as an outcome measure has not been assessed similarly. In this study, we aimed to determine whether meaningful information relative to shape, and relapse in particular, could be assessed using the IFA. METHODS: Patients with operatively treated isolated metopic synostosis were identified and included based on the availability of "previously obtained" low-dose computerized tomography (CT) scans at (1) preoperative and 2 postoperative (2) postoperative day-3 and (3) 1 year time points...

Sagittal craniosynostosis (SC) is the most common type of premature suture fusion presenting in approximately 1 in every 5000 births with a 3:1 male:female ratio. The most common indication for surgery is the improvement of the cosmetic appearance of the skull, since a cranial deformation may have a significant psychosocial impact on affected patients. Relief from raised intracranial pressure is a further indication for surgery, although an increased intracranial pressure (ICP) can be demonstrated only in a minority of affected children at diagnosis...

PURPOSE: Skull radiography (SR) and Computed Tomography (CT) are still proposed as the first-line imaging choice for the diagnosis of craniosynostosis (CS) in children with abnormal head shape, but both techniques expose infants to ionizing radiation. Several studies shown that ultrasound may play an important role in the diagnosis of craniosynostosis. The aim of our study is to assess the diagnostic accuracy of cranial ultrasound scan (CUS) and confirm if it is a reliable first step imaging evaluation for the diagnosis of craniosynostosis in newborn...

INTRODUCTION: Although single-suture craniosynostosis is diagnosed sporadically during pregnancy, timely referral is critical for its treatment. Additionally, craniosynostosis leads to increased maternofetal trauma during birth. In the Netherlands, 95% of pregnant women receive a standard ultrasound at around 20 weeks of gestation, potentially an ideal setting for detecting craniosynostosis prenatally. To enhance the prenatal detection of the metopic and the sagittal suture synostosis, we wished to identify new screening parameters...

OBJECTIVE Outcome studies for sagittal strip craniectomy have largely relied on the 2D measure of the cephalic index (CI) as the primary indicator of head shape. The goal of this study was to measure the 2D and 3D changes in head shape that occur after sagittal strip craniectomy and postoperative helmet therapy. METHODS The authors performed a retrospective review of patients treated with sagittal strip craniectomy at their institution between January 2012 and October 2015. Inclusion criteria were as follows: 1) isolated sagittal synostosis; 2) age at surgery < 200 days; and 3) helmet management by a single orthotist...

Fusion of the atlas with the occipital bone is a rare congenital dysplasia known as occipitalization of the atlas, occipitocervical synostosis, assimilation of the atlas, or atlanto-occipital fusion. It is a component of the paraxial mesodermal maldevelopment and commonly associated with other dysplasias of the craniovertebral junction. External auditory canal atresia or external aural atresia is a rare congenital absence of the external auditory canal. It occurs as the consequence of the maldevelopment of the first pharyngeal cleft due to defects of cranial neural crest cells migration and/or differentiation...

BACKGROUND: Minimizing the ionizing radiation dose to children is fundamental to pediatric radiology. The most widely accepted imaging examination for evaluating craniosynostosis is computed tomography (CT) of the head, an examination that involves ionizing radiation. OBJECTIVE: To determine if sonography of the cranial sutures is an adequate screening examination for the diagnosis of craniosynostosis in patients with abnormal skull shape. MATERIALS AND METHODS: A retrospective review of all cranial suture ultrasound (US) examinations performed during the course of a 3-year period (July 2012 - September 2015) was undertaken...

OBJECTIVE Single-suture craniosynostosis (SSC), the premature fusion of a cranial suture, is characterized by dysmorphology of the craniofacial skeleton. Evidence to suggest that children with SSC are at an elevated risk of mild to moderate developmental delays and neurocognitive deficits is mounting, but the associations among premature suture fusion, neuroanatomy, and neurocognition are unexplained. The goals of this study were to determine 1) whether differences in the brain are present in young children with the 2 most common forms of SSC (sagittal and metopic) several years following surgical correction, and 2) whether the pattern of differences varies by affected suture (sagittal or metopic)...

Craniosynostosis (CS) has a prevalence of approximately 1 in every 2000 live births and is characterized by the premature fusion of one or more cranial sutures. Failure to maintain the cell lineage boundary at the coronal suture is thought to be involved in the pathology of some forms of CS. The Ephrin family of receptor tyrosine kinases consists of membrane-bound receptors and ligands that control cell patterning and the formation of developmental boundaries. Mutations in the ephrin A4 (EFNA4) and ephrin B1 (EFNB1) ligands have been linked to nonsyndromic CS and craniofrontonasal syndrome, respectively, in patient samples...
