BACKGROUND: Heterotopic ossification (HO) is defined as ectopic bone formation following traumatic brain injury. Patients typically develop lesions in the hips, knees, and elbows that cause pain, restricted range of motion, nerve impingement, and pressure ulcers. CASE REPORT: We report an unusual presentation of HO in an 18-year-old male who was involved in a motor vehicle accident and subsequently developed malignant intracranial pressure. His HO developed following bilateral craniectomies in which 2 different dural substitutes were used...

REVIEW
Matthew Piazza, M Sean Grady
Cranioplasty following craniectomy for trauma is a common, safe neurosurgical procedure that restores the natural cosmesis and protective barrier of the skull and may be instrumental in normalizing cerebrospinal fluid dynamics after decompressive surgery. Understanding the factors influencing patient selection and timing of cranioplasty, the available materials and methods of skull reconstruction, and the technical nuances is critical for a successful outcome. Neurosurgeons must be prepared to manage the complications specific to this operation...

Perivascular regions of the brain harbor multipotent stem cells. We previously demonstrated that brain pericytes near blood vessels also develop multipotency following experimental ischemia in mice, and that these ischemia-induced multipotent stem cells (iSCs) can contribute to neurogenesis. However, it is essential to understand the traits of iSCs in the post-stroke human brain for possible applications in stem cell-based therapies for stroke patients. Here we report for the first time that iSCs can be isolated from the post-stroke human brain...

INTRODUCTION: Radiation-free 3D post-operative sequential follow-up in craniosynostosis is hindered by the lack of consistent markers restricting evaluation to subjective comparison. However, using the computed cranial focal point (CCFP), it is possible to perform correct sequential image superposition and objective evaluation. We used this technique for mean volume and shape change evaluation of the head utilizing 3D photos after endoscopically assisted trigonocephaly surgery. METHODS: We performed a mean head shape and volume evaluation on age grouped 3D photos (n = 86) of children who underwent endoscopically assisted strip craniectomy with helmet therapy...

INTRODUCTION: Acute subdural hematoma (SDH) is a major cause of morbidity following severe traumatic brain injury. Surgical evacuation of the hematoma, either via craniotomy or craniectomy, is the mainstay of treatment in patients with progressive neurological deficits or significant mass effect. However, the decision between either procedure remains controversial. METHODS: A literature search using major online databases and a manual search of reference on the topic of craniotomy and craniectomy for evacuation of subdural hematoma until September 2016 was performed...

OBJECTIVE Decompressive craniectomy is an established therapy for refractory intracranial hypertension. Cranioplasty following decompressive craniectomy not only provides protection to the brain along with cosmetic benefits, but also enhances rehabilitation with meaningful functional recovery of potentially reversible cortical and subcortical damaged areas of the affected as well as the contralateral hemisphere. The aim of the study was to assess neurological and cognitive outcome as well as cerebral blood flow after cranioplasty...

OBJECTIVE Outcome analysis of comatose patients (Hunt and Hess Grade V) after subarachnoid hemorrhage (SAH) is still lacking. The aims of this study were to analyze the outcome of Hunt and Hess Grade V SAH and to compare outcomes in the current period with those of the pre-International Subarachnoid Aneurysm Trial (ISAT) era as well as with published data from trials of decompressive craniectomy (DC) for middle cerebral artery (MCA) infarction. METHODS The authors analyzed cases of Hunt and Hess Grade V SAH from 1980-1995 (referred to in this study as the earlier period) and 2005-2014 (current period) and compared the results for the 2 periods...

REVIEW
S Honeybul, K M Ho, G R Gillett
OBJECTIVE: There is little doubt that decompressive craniectomy can reduce mortality. However, there is concern that any reduction in mortality comes at an increase in the number of survivors with severe neurological disability. METHOD: Over the past decade there have been several randomised controlled trials comparing surgical decompression with standard medical therapy in the context of ischaemic stroke and severe traumatic brain injury. The results of each trial are evaluated...

Craniosynostosis is a condition in which one or more of the cranial sutures have fused prematurely, affecting the growth pattern and contours of the infant skull. The pterion is the junction of temporal, frontal, parietal, and sphenoid bones of the skull. We present a case of unilateral pterional craniosynostosis, which was treated with strip craniectomy and helmet therapy.

INTRODUCTION: Compound elevated skull fractures (CESF) are rare traumatic injuries. To date, only 27 cases have been reported. METHODS: The authors report three cases of CESF managed at their institute. All were middle-aged males. The mechanism was assault by sharp-edged objects in two and road traffic accident (RTA) in one case. One underwent simple suturing; debridement and decompressive craniectomy was done in the remaining two cases. Good and poor outcomes were noted in one case each, while one died...

This report describes a rare but life-threatening case of a suicide attempt initially considered as intentional overdose at the emergency department. Persistent altered mental status, despite normal toxicology investigations, led the attending team to order a head computed tomography scan, which revealed a bilateral penetrating nail gun injury with a right temporal hematoma for which a decompressive craniectomy was performed. Although voluntary intoxication is the most frequent form of suicide attempt, emergency physicians must be alert and maintain a broad differential diagnosis...

INTRODUCTION: Watertight reconstruction to separate the intradural compartment from the sinonasal cavities is crucial after endoscopic resection with transnasal craniectomy (ERTC) for naso-ethmoidal tumors. Three-layer reconstruction with the iliotibial tract (TRITT) is a safe and reliable alternative when vascularized flaps are not available. SURGICAL TECHNIQUE: The iliotibial tract graft is harvested on the lateral aspect of the thigh and divided in three portions, which are positioned in a multi-layered fashion to close the skull base defect...

PURPOSE: Patients who received decompressive craniectomy (DC) are usually not regarded to qualify for brain death (BD) as intracranial pressure (ICP) is not assumed to reach levels critical enough to cause cerebral perfusion failure. Here we investigated the incidence of BD after DC and analyzed the pathophysiological mechanisms. MATERIALS AND METHODS: We searched our chart records of patients with DC for individuals who developed BD (2010-2016). We then analyzed the course of ICP and cerebral perfusion pressure (CPP) prior to BD and results from radiological tests that aim at demonstrating loss of cerebral perfusion in BD...

Background and Study Aims Surgical treatment for acute subdural hematomas (ASDHs) in elderly patients is still considered unsatisfactory. Series focusing on the use of conventional craniotomy or decompressive craniectomy in such patients report discouraging results. Glasgow Coma Scale (GCS) score at admission seems to be crucial in the decision-making process. Deteriorating patients with a GCS score between 9 and 11 are those who would benefit most from the surgical treatment. Unfortunately, elderly patients often present other comorbidities that greatly increase the risk of severe complications after major neurosurgical procedures under general anesthesia...

Background The purpose of this study was to evaluate the impact of the early craniectomy on mortality. Hypothesis Early craniectomy within 4 hours of hospital arrival will reduce in-hospital mortality. Methods Data were retrieved from the National Trauma Data Bank data set (RDS_2007-RDS_2010). All craniectomies performed on patients with a blunt mechanism of head injury within 24 hours of admission were included in the study. In-hospital mortality was the main outcome of interest. Results A total of 942 patients qualified for the study...
