PURPOSE: The effect of synostosis is not confined to the immediate vicinity of the suture. The authors hypothesized metopic craniosynostosis results in migration of lateral structures from midline, and differences in segmental volume of the cranial fossa. METHODS: A retrospective case-controlled cohort analysis of patients with nonsyndromic metopic craniosynostosis was performed. Craniometric angles, distances to landmarks from midline, cephalic index, and segmented volume ratios were calculated...

OBJECTIVE: Cranial vault remodeling surgery for craniosynostosis carries the potential risk of dural venous sinus injury given the extensive bony exposure. Identification of the dural venous sinuses can be challenging in patients with craniosynostosis given the lack of accurate surface-localizing landmarks. Computer-aided design and manufacturing (CAD/CAM) has allowed surgeons to pre-operatively plan these complex procedures in an effort to increase reconstructive efficiency. An added benefit of this technology is the ability to intraoperatively map the dural venous sinuses based on pre-operative imaging...

BACKGROUND: Nonsyndromic craniosynostosis is a relatively common craniofacial anomaly and various techniques were introduced to achieve its operative goals. Authors found that by using smaller bone fragments than that used in conventional cranioplasty, sufficiently rigid bone union and effective regeneration capacity could be achieved with better postoperative outcome, only if their stable fixation was ensured. METHODS: Through bicoronal incisional approach, involved synostotic cranial bone together with its surrounding areas were removed...

We report a case of surgical management of Crouzon syndrome with multisuture craniosynostosis presenting with increased intracranial pressure (ICP) manifesting with chronic papilledema without ventriculomegaly. A 12-month-old boy had complete resolution of papilledema after posterior cranial vault distraction followed by staged fronto-orbital advancement. Expansion of the cranial vault with posterior distraction osteogenesis posed an elegant treatment, obviating ventriculoperitoneal shunt placement for cerebrospinal fluid (CSF) diversion...

Hominoid cranial evolution is characterized by substantial phenotypic diversity, yet the cause of this variability has rarely been explored. Quantitative genetic techniques for investigating evolutionary processes underlying morphological divergence are dependent on the availability of good ancestral models, a problem in hominoids where the fossil record is fragmentary and poorly understood. Here, we use a maximum likelihood approach based on a Brownian motion model of evolutionary change to estimate nested hypothetical ancestral forms from 15 extant hominoid taxa...

Only 5-10% of osteosarcomas arise from the craniofacial bones. We report the case of a 14-year-old female patient who presented with headache and a mass that had been growing in the left frontoparietal region for six months. We describe the findings on conventional radiography, computed tomography, and magnetic resonance imaging.

BACKGROUND: The authors hypothesized that patients with unicoronal craniosynostosis (UCS) have deviation of the vault, cranial base, and face resulting in significant differences in skull base morphology and segmental cranial vault volume relative to nonaffected controls. METHODS: Unicoronal craniosynostosis patients were collected from the authors' IRB-approved, prospective, craniofacial registry; controls were from a trauma registry. Mimics software was used to compare those with UCS to controls for a series of standardized craniometric angles and distances...

BACKGROUND: Sagittal craniosynostosis typically presents shortly after birth, with a scaphocephalic head shape, and is addressed surgically for functional and aesthetic concerns. This study highlights the authors' experience with a challenging patient population: those with phenotypically mild, missed, and late-developing sagittal craniosynostosis. METHODS: A prospective cohort study was conducted for all cases of sagittal craniosynostosis presenting to the authors' institution between July of 2013 and December of 2015...

Craniosynostosis is a complex disease condition, which involves premature fusion of cranial vault sutures and lacks desirable treatment. Previous studies have demonstrated decreased proliferation rate of osteoblasts and downregulated expression of glypican 3 (GPC3) in syndromic craniosynostosis patients. In this study, quantitative and qualitative analysis were utilized to assess the effect of GPC3 in human fetal osteoblastic cell line, hFOB 1.19. Lentiviral transfection efficiency with green fluorescent protein images was obtained after 72 hours...

OBJECTIVES: This study aims to identify the patterns and prevalence of violence-related skull trauma (including the cranium and mandible) among a large sample of skeletons from medieval London (1050-1550 AD). MATERIALS AND METHODS: In total, data from 399 skulls, representing six different sites from across medieval London, were analyzed for evidence of trauma and assessed for the likelihood that it was caused by violence. The sites include the three parish cemeteries of St Nicholas Shambles (GPO75), St Lawrence Jewry (GYE92), and St Benet Sherehog (ONE94); the two monastic houses of London Blackfriars (PIC87) and St Mary Graces (MIN86); and the early inmate cemetery from the medieval hospital of St Mary Spital (NRT85)...

Nowadays the reconstruction of craniofacial defects can be performed with different kinds of materials, which include the bone and the so-called biomaterials, which have the advantage of not needing a surgical site donor. Among these materials, great attention is given to polymers. In this large group, current attention is focused on the castor oil polymer, since this polymer is biocompatible, low cost, and has adequate strength for reconstruction of the craniomaxillofacial complex. This study aims to report the use of a prosthetic castor oil polymer for reconstruction of extensive defect, caused by a trauma, in the temporoparietal region...

A rare patient of reducible eyeball luxation after cranioplasty in a child Crouzon syndrome was reported. To remedy the patient's chronic intracranial hypertension and brachycephaly, orbitofrontal advancement and cranial vault remodeling were carried out. About 25 days of postoperation, an acute eyeball luxation was observed, with the presence of a subcutaneous accumulation of liquid in the bilateral temporal regions. The dislocated eyeballs were brought back by applying gentle manual pressure. The patient received a conservative treatment without a tarsorrhaphy...

The spheno-occipital synchondrosis (SOS) in cranial base is an important growth center for the craniofacial skeleton, and also is a guide rail for development of the maxilla, midface, and mandible. Previous studies showed that SOS may be a treatment target for youngsters with midfacial hypoplasia and small cranial vault secondary to craniosynostosis. However, most of studies about the SOS are based on imaging data. In this study, we try to explore the characteristics of postnatal development of the mouse SOS based on histological analysis...

BACKGROUND: Only a few studies investigating the optimal time point at which to start orthotic treatment for deformational plagiocephaly take into account the severity of skull asymmetry. The present study performs a three-dimensional analysis of the effects of age and severity of asymmetry on the final outcome. METHODS: A total of 144 patients with deformational plagiocephaly treated by molding orthosis were examined and divided into three age groups (group I, <24 weeks; group II, ≥24 to <32 weeks; and group III, ≥32 weeks) and two severity levels (mild to moderate, 30-degree cranial vault asymmetry ≥3 mm to ≤12 mm; and moderate to severe, 30-degree cranial vault asymmetry >12 mm)...
