OBJECTIVE: Intracranial meningiomas are typically benign extracerebral tumors derived from dural arachnoid cells. Predominantly, these tumors are effectively managed surgically, but the prognosis is heavily dependent on tumors' histological heterogeneity and its location. It is known that reproductive and hormonal factors increase the risk for meningioma in adult females, but their prognostic value still remains controversial. This study's aim was to examine possible correlation between tumor location and outcome, and to evaluate prognostic value of the proposed simple tumor localization scale in predicting the management outcome of intracranial meningioma...

Cranium bifidum occultum is a disorder of skull ossification presenting as an enlarged posterior fontanelle in the upper posterior angle of the parietal bone near the intersection of the sagittal and lambdoid sutures. The standard treatment for cranium bifidum occultum is observation. We present a case of a 5-year-old boy who presented with a 15x4.5 cm midline posterior cranial vault defect consistent with diagnosis of cranium bifidum occultum associated with orbital hypertelorism and a widened nose. The patient underwent posterior vault reconstruction for correction of cranium bifidum occultum defect followed by bifrontal craniotomy and orbital box osteotomies for correction of orbital hypertelorism and nasal deformity...

Superior semicircular canal dehiscence (SSCD) is a bony defect in the middle cranial fossa floor that results in an abnormal connection between the inner ear and cranial vault. Although the etiology of SSCD remains unclear, an inappropriately thin or fragile temporal bone likely predisposes an individual towards developing SSCD. Ehlers-Danlos syndrome (EDS) constitutes a group of genetic connective tissue disorders caused by a defect in the production, processing, or structure of collagen, or its associated proteins...

OBJECTIVE: Virtual Surgical Planning (VSP) and computer-aided design/computer-aided manufacturing (CAD/CAM) have recently helped improve efficiency and accuracy in many different craniofacial surgeries. Research has mainly focused on the use in the adult population with the exception of the use for mandibular distractions and cranial vault remodeling in the pediatric population. This study aims to elucidate the role of VSP and CAD/CAM in complex pediatric craniofacial cases by exploring its use in the correction of midface hypoplasia, orbital dystopia, mandibular reconstruction, and posterior cranial vault expansion...

Due to their flexibility, sutures are regions that experience greater strains than the surrounding rigid cranial bones. Cranial sutures differ in their degree of interdigitation or complexity. There is evidence indicating that a more convoluted suture better enables the absorption of high stresses coming from dynamic masticatory forces, and other functions. The Order Rodentia is an interesting clade to study this because of its taxa with diverse chewing modes. Due to repeated loading resulting from gnawing and grinding, energy absorption by the sutures might be a crucial factor in these mammals...

Encephaloceles are herniations of brain parenchyma through congenital or acquired osseous-dural defects of the skull base or cranial vault. Different types of symptoms, due to CSF fistulas, meningitis, or seizures, are often associated with this condition. The authors present a rare case of spontaneous right frontal parasagittal encephalocele in a 70-year-old man who was experiencing a spastic progressive paresis of his left lower limb. Results of routine electrophysiological workup (motor evoked potentials, somatosensory evoked potentials, and electroneuromyography), as well as those of MRI of the spinal cord, were normal...

The frequency of sagittal crest expression and patterns of sagittal crest growth and development have been documented in hominoids, including some extinct hominin taxa, and the more frequent expression of the sagittal crest in males has been traditionally linked with the need for larger-bodied individuals to have enough attachment area for the temporalis muscle. In the present study, we investigate sagittal cresting in a dentally mature sample of four hominoid taxa (Pan troglodytes schweinfurthii, Gorilla gorilla gorilla, Pongo pygmaeus pygmaeus and Hylobates lar)...

BACKGROUND: Posterior cranial vault distraction (PCVD) is a technique widely used in surgical treatment of craniosynostosis when cranial expansion is required. It has proven to be safe and to allow a significant increase of intracranial volume. OBJECTIVE: To evaluate increases in intracranial volume as a result of PCVD performed in Oulu Craniofacial center using 2 different methods based on 3-dimensional (3-D) photogrammetric imaging or plain skull radiographs. METHODS: All children less than 16 yr of age who were treated by PCVD (n = 31) from 2009 to 2015 at the Oulu Craniofacial Center were included...

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...

BACKGROUND: Pediatric complex cranial vault reconstruction (CCVR) surgery is often associated with significant blood loss and transfusion. The authors recently changed our transfusion practice during CCVR to using whole blood (WB) instead of reconstituted blood (RB). The aim of this study was to assess the impact of this practice change. Our hypothesis was that replacement with WB would be as effective as RB for the outcomes of total perioperative blood donor exposures (BDEs) and the incidence of laboratory evidence of postoperative coagulopathy...

Reconstruction of the craniosynostosis deformity is a relatively safe operation with low overall complication risks. Despite expected risk of significant blood loss, life-threatening bleeding is relatively rare, and there is a low incidence of reported deaths in the literature. Several modalities have been described for perioperative mitigation of blood loss and transfusion requirements. Due to the low overall risk of life-threatening bleeding and circulatory collapse, it is judicious that any potential causes of such unusual but potentially significant fatal bleeding complication be evaluated and reported to increase awareness for craniofacial surgeons treating these conditions...

There are many surgical techniques for craniosynostosis. However, the indications for and timing of surgery still remain unclarified. Most of the skull growth in craniosynostosis is completed in the first year, and the bone is strong enough to undergo distraction osteogenesis. However, previous reports showed that patients operated on before 1 year of age had better IQ than those operated later in life. This report aims to consider the best timing for cranial expansion and surgical strategy for Apert syndrome...

This report describes the clinical, macroscopic, histopathological and immunohistological features of a spontaneous multicentric extraskeletal sarcoma in an adult male African hedgehog (Atelerix albiventris). It also provides a succinct up-to-date review on neoplasia in this species. On autopsy examination, main gross findings included a moderately demarcated cranial mass and a multilobulated, caudal intra-abdominal mass. The cranial mass had perforated the underlying temporal and occipital bones and had extended into the cranial vault and was compressing the surface of the cerebellum and cerebrum...
