AIMS: Growing skull fracture (GSF) is a rare complication resulting from diastatic enlargement of a pediatric skull fracture. Orbitocranial GSF is a distinct variant with more complex management issues due to the displacement of the globe. This study aims to discuss surgical considerations in the management of GSF, with particular reference to orbitocranial variants. METHODS: We conducted a retrospective analysis of 7 children operated for GSFs at our institute from 2008 to 2015...

Various biomimetic scaffolds with hierarchical micro/nanostructures are designed to closely mimic native extracellular matrix network and to guide cell behavior to promote structural tissue generation. However, it remains a challenge to fabricate hierarchical micro/nanoscaled fibrous scaffolds with different functional components that endow the scaffolds with both biochemical and physical features to exert different biological roles during the process of tissue healing. In this study, a biomimetic designed micro/nanoscaled scaffold with integrated hierarchical dual fibrillar components is fabricated in order to repair dura mater and prevent the formation of epidural scars via collagen molecule self-assembly, electrospinning, and biological interface crosslinking strategies...

INTRODUCTION: Chiari malformation Type I (CM) is the main congenital malformation disease of the craniovertebral junction. The ideal surgical treatment is still controversial. Invasive procedures inside CSF space and associated with dural repair are considered the gold standard, however a less invasive surgery with isolated bone decompression without dural opening may be possible in selected patients.. Our study evaluates the efficacy of intra-operative CSF flow measurement with ultrasonography (USG) as a determining parameter in the selection of these patients...

Duraplasty is necessary in nearly 30% of all neurological surgeries. Different tissues and materials have been evaluated in dura mater repair or as dural substitutes in neurosurgery. The aim was to evaluate the biocompatibility of the bacterial cellulose (BC) membranes, produced from sugarcane molasses, for dural defect repair in rats. Forty adults males Wistar rats divided into two groups: a control (ePTFE) and an experimental (BC). Bilateral frontoparietal craniectomy was performed, and a dural defect was created...

Chiari malformation type I (CM-I) is a congenital neurosurgical disease about the herniation of cerebellar tonsil through the foramen magnum. A variety of surgical techniques for CM-I have been used, and there is a controversy whether to use posterior fossa decompression with duraplasty (PFDD) or posterior fossa decompression without duraplasty (PFD) in CM-I patients. Here, we compared the clinical results and effectiveness of PFDD and PFD in adult patients with CM-I. The cases of 103 adult CM-I patients who underwent posterior fossa decompression with or without duraplasty from 2008 to 2014 were reviewed retrospectively...

Natural materials such as collagen and alginate have promising applications as dural graft substitutes. These materials are able to restore the dural defect and create optimal conditions for the development of connective tissue at the site of injury. A promising material for biomedical applications is chitosan-a linear polysaccharide obtained by the deacetylation of chitin. It has been found to be nontoxic, biodegradable, biofunctional and biocompatible in addition to having antimicrobial characteristics. In this study we designed new chitin-chitosan substitutes for dura mater closure and evaluated their effectiveness and safety...

OBJECTIVE: A common symptom of Chiari I malformation (CIM) is headache, which is diagnosed using non-validated criteria from the International Headache Society (IHS). CIM-associated headaches should resolve following neurosurgical treatment of the malformation by foramen magnum decompression (FMD). We aimed to validate the IHS criteria and determine (1) the efficacy of FMD in treating headache and (2) whether duraplasty confers an advantage over simple bony decompression in the treatment of this symptom...
