Context: Decompressive craniectomy followed by cranioplasty (CP) uses autologous craniectomy flaps or synthetic materials like titanium. Sterilization and preservation methods for the autologous bone flaps continue to be the surgeon's choice. Aim: This study aimed to assess the short-term as well as long-term clinical outcomes of CP using autoclaved autologous bone grafts. Settings and Design: This retrospective observational study was performed on patients admitted in a tertiary care teaching neurosurgery department...

Objective: After a rigorous management of increased intracranial pressure by decompressive craniectomy (DC), cranioplasty (CP) is usually carried out for functional and cosmetic purposes. However, the optimal timing of CP remains controversial. Our study aims to analyze the relationship between the optimal timing of CP and the post-operative complications. Methods: From January 2013 to December 2015, ninety patients who underwent CP in a single institution were analyzed...

BACKGROUND: Autologous bone grafts are still the best materials for calvarial reconstruction. In the past, rib, iliac crest, and cranial bone have been used for the reconstruction of the calvarial defects. However, the use of mandibular outer cortex bone graft in calvarial defects reconstruction is poorly reported in literature. This study focused on using the mandibular outer cortex bone grafts for calvarial defects. METHODS: From October 2004 to July 2016, there were a total of 13 patients in this study who underwent cranioplasty with mandibular outer cortex bone grafts to reconstruction calvarial defects...

Scalp and calvarial masses are common in children and the differential diagnosis is broad. The authors recently cared for a child with an unusual fibro-osseous lesion of the temporal bone that has previously not been described in the pediatric neurosurgery literature. A 10-year-old girl presented with a firm, slowly enlarging protuberant mass arising from the squamous suture of the temporal bone without intracranial extension. The mass was removed en bloc through a temporal craniectomy and cranioplasty was performed...

BACKGROUND AND IMPORTANCE: The authors report a novel external scalp retraction technique for sunken skin flap syndrome (SSFS). CLINICAL PRESENTATION: A 48-year-old male patient suffered neurological deterioration due to SSFS after decompressive craniectomy. Cranioplasty is the gold standard for therapeutic management of SSFS, but could not be performed due to intracranial wound infection. The patient underwent external fixation of a metal plate as a frame for the skull and the scalp was pulled outward to the frame by skin suture...

AIM: A decompressive craniectomy is a potentially life-saving surgical procedure for raised intracranial pressure. Once it has been performed, patients are obliged to undergo a second procedure with cranioplasty. The aim of this study was to investigate the outcomes and associated complications after delayed cranioplasty using autologous, cryopreserved bone. MATERIAL AND METHODS: This retrospective study included 57 consecutive patients treated with cranioplasty with autologous cryopreserved bone for various conditions causing increased intracranial pressure due to brain swelling...

INTRODUCTION: Decompressive craniectomy (DC) is a lifesaving procedure but is associated to several post-operative complications, namely cerebrospinal fluid (CSF) dynamics impairment. The aim of this multicentric study was to evaluate the incidence of such CSF alterations after DC and review their impact on the overall outcome. MATERIAL AND METHODS: We performed a retrospective multicentric study to analyze the CSF disorders occurring in children aged from 0 to 17 years who had undergone a DC for traumatic brain injury (TBI) in the major Departments of Pediatric Neurosurgery of France between January 2006 and August 2016...

Cranial repair after traumatic brain injury in children is still burdened by unsolved problems and controversial issues, mainly due to the high rate of resorption of autologous bone as well as the absence of valid alternative material to replace the autologous bone. Indeed, inert biomaterials are associated to satisfactory results in the short period but bear the continuous risk of complications related to the lack of osteointegration capacity. Biomimetic materials claiming osteoconductive properties that could balance their mechanical limits seem to allow good cranial bone reconstruction...

PURPOSE: Complications in wound healing after neurosurgical operations occur often due to scarred dehiscence with skin blood perfusion disturbance. The standard imaging method for intraoperative skin perfusion assessment is the invasive indocyanine green video angiography (ICGA). The noninvasive dynamic infrared thermography (DIRT) is a promising alternative modality that was evaluated by comparison with ICGA. METHODS: The study was carried out in two parts: (1) investigation of technical conditions for intraoperative use of DIRT for its comparison with ICGA, and (2) visual and quantitative comparison of both modalities in a proof of concept on nine patients...

Objective: To quantitatively measure the degree of bone flap resorption (BFR) following autologous bone cranioplasty and to investigate factors associated with BFR. Methods: We retrospectively reviewed 29 patients who underwent decompressive craniectomy and subsequent autologous bone cranioplasty between April 2005 and October 2014. BFR was defined as: 1) decrement ratio ([the ratio of initial BF size/craniectomy size]-[the ratio of last BF/craniectomy size]) >0...

PURPOSE: Temporal hollowing deformity (THD) is a visible concavity/convexity in the temporal fossa; a complication often seen following neurosurgical/craniofacial procedures. Although numerous techniques have been described, no study to date has shown the healthcare costs associated with temporal hollowing correction surgery. Thus, the purpose here is to compare and contrast the direct costs related to temporal cranioplasty using various methods including: liquid poly-methyl-methacrylate (PMMA) implants with screw fixation, prebent, modified titanium mesh implants, and customized cranial implants (CCIs) with dual-purpose design...

OBJECTIVE Cranial defects can result from trauma, infection, congenital malformations, and iatrogenic causes and represent a surgical challenge. The current standard of care is cranioplasty, with either autologous or allogeneic material. In either case, the intrinsic vascularity of the surrounding tissues allows for bone healing. The objective of this study was to determine if mechanotransductive gene manipulation would yield non-weight-bearing bone regeneration in a critical size calvarial defect in mice. METHODS A mouse model of Sost deletion in Sost knockout (KO) mice was created in which the osteocytes do not express sclerostin...

Case: An 84-year-old man with subarachnoid hemorrhage underwent craniotomy and clipping with external decompression. Perfusion magnetic resonance imaging showed subclinical sinking skin flap syndrome, and he underwent cranioplasty on postoperative day 58. No problems occurred during the operation, but cerebral edema and hemorrhage were recognized on immediate postoperative computed tomography. Edema continued to progress, but edema and bleeding eventually improved without additional surgery...

The risk of seizure is increased following brain surgery such as cranioplasty. Patients with seizures that are treated with valproic acid (VPA) may have a decreased risk of further seizures. To verify microRNA (miR)‑155 as a potential biomarker for the occurrence of seizures, reverse transcription quantitative polymerase chain reaction (RT‑qPCR) was used. Computational analysis and luciferase reporter assay was performed to identify the putative target of miR‑155. RT‑qPCR and western blot analyses were used to determine the expression level of miR‑155, sodium voltage‑gated channel α subunit 1 (SCN1A) mRNA and protein...

Cranioplasty is a comparatively simple neurosurgical procedure, and fatal complications are rare. This report describes two cases of critical brain swelling after otherwise uneventful cranioplasty. Both cases had subarachnoid hemorrhage and extremely similar clinical courses. They underwent decompressive craniotomy and clipping in the acute phase and had cranioplasty in the chronic phase, resulting in serious cerebral swelling and death. Deep venous sinus thrombosis was revealed in the autopsy for one case...

BACKGROUND: management of encephaloceles is challenging when massive brain herniation is present. In such instances, an expansile cranioplasty may be attempted so as to preserve some herniated brain tissue. Complications such as wound dehiscence, CSF leak and scalp necrosis are postoperative concerns. The treatment of scalp necrosis with dural and brain exposure is certainly a challenge, due to the complexity of flap techniques in such a young age. Herein we describe the use of a novel technique for the management of a scalp necrosis and dehiscence in an infant...

OBJECTIVE: Decompressive craniectomy (DC) is used to treat intractable intracranial hypertension following severe traumatic brain injury (TBI). Cranioplasty (CP) is typically performed weeks or months later. However, the optimal timing for CP is unknown. We aimed to determine the earliest possible time point for CP. METHODS: We retrospectively reviewed brain computed tomography (CT) images from 159 patients who underwent CP following DC for TBI at 3 hospitals. We determined the earliest possible day for CP by reviewing the resolution of intracranial pressure in serial brain CT images between DC and CP...

BACKGROUND: Cranioplasty is considered a low-risk operation in the field of neurosurgery following decompression craniectomy (DC). Well-known complications after cranioplasty, such as infection, seizure, and titanium plate exposure, may not threaten the lives of patients. Unfortunately, there are many fatal complications that are under reported. In this study, we report a case and perform a literature review to introduce malignant cerebral swelling, which is regarded as a devastating complication...
