Cranial defects occur most commonly as a sequelae to trauma, the incidence being as high as 70%. The successful management of a case of trauma in an emergency situation requires quick evacuation of the hematoma, repair of the dura, and the scalp but not necessarily the integrity of the calvarial segment as an immediate measure. So the reconstruction of the calvarial defect in these cases is mos...

BACKGROUND The aim of this study was to determine the osteoconductivity of biphasic calcium phosphate collagen composite (BCPC) in rabbit calvarial defect model by comparing with biphasic calcium phosphate (BCP). Four 8 mm diameter bicortical calvarial defects were made in ten rabbits. Each of the defects was randomly assigned and filled with 1) collagen sponge, 2) BCP, 3) BCPC, and 4) nothing ...

This study was designed to investigate the optimal combination of known osteogenic biomaterials with shape conforming struts to achieve calvarial vault reconstruction, using a canine model. Eighteen adolescent beagles were divided equally into 6 groups. A critical-size defect of 6 x 2 cm traversed the sagittal suture. The biomaterials used for calvarial reconstruction were demineralized perfora...

BACKGROUND Tuberculosis is endemic in developing countries. However, calvarial tuberculosis is rare, even in areas where tuberculosis is endemic. In the literature, only few case series of calvarial tuberculosis have been reported. AIM To report a case series of 11 patients with calvarial tuberculosis, and discuss their presentation and management. MATERIALS AND METHODS This study is a retr...

The objective of this study was to determine the relative efficacy of currently available alloplastic bone repair materials in the healing of rat calvarial defects histologically, histomorphometrically and biochemically. A representative material was selected from six major classes of bone repair materials and placed in 4 mm diameter calvarial defects of 6-week-old male Sprague-Dawley rats (fiv...

Cranioplasty is a common, but formidable surgical procedure for neurosurgeons, in patients with scalp and / or calvarial defects. This procedure can be simple or complex. The main objectives of cranioplasty are: To achieve primary wound healing, obliterate dead space, and seal off sterile cranial areas from contaminated oronasal cavities, to restore the normal barriers protecting the intracrani...

BACKGROUND AND OBJECTIVES The aim of this study was to compare culture-expanded, bone marrow-derived mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) loaded to biphasic calcium phosphate (BCP) bone ceramic in the repair of rat calvarial bone. MATERIALS AND METHODS Critical-size (7 mm dia.) calvarial defects were prepared in the frontal-parietal bones of 90 adult female Sprague-Daw...

PURPOSE Fibronectin (FN) has been shown to stimulate bone regeneration in animal models. The aim of this study was to evaluate the capacity of bovine bone mineral coated with synthetic oligopeptides to enhance bone regeneration in rabbit calvarial defects. METHODS Oligopeptides including fibrin-binding sequences of FN repeats were synthesized on the basis of primary and tertiary human plasma ...
