Predictors of Surgical Site Infection in Cranioplasty: A Retrospective Analysis of Subcutaneously Preserved Bone Flaps in Abdominal Pockets.

Decompressive craniectomy (DC) is a life-saving surgical procedure performed to manage intracranial hypertension. Once performed, patients are obligated to undergo another surgical procedure known as cranioplasty to reconstruct the cranial defect. Cranioplasty still has one of the highest rates of infection. The factors contributing to the high rate of surgical site infection (SSI) after cranioplasty are not well established. This study aims to estimate the incidence of SSI and determine its possible risk f...

Outcomes and Complications of Pediatric Cranioplasty: A Systematic Review.

In recent years, material choice for cranioplasty is still controversial, which brings complexity to this seemingly straightforward procedure. PEEK, a tough, rigid, biocompatible material, has been used more recently in cranioplasty to provide better protection. The aim of this review is to summarize the outcome of research conducted on the material for cranioplasty applications. We also reviewed the co...

Patient-Specific Reconstruction Utilizing Computer Assisted 3D Modelling for Partial Bone Flap Defect in Hybrid Cranioplasty.

Decompressive craniectomy is a life-saving procedure in the setting of malignant brain swelling. Patients who survive require cranioplasty for anatomical reconstruction and cerebral protection. Autologous cranioplasty remains the commonest practice nowadays, but partial bone flap defects are frequently encountered. The authors, therefore, seek to develop a new technique of reconstruction for cranioplasty candidate with partial bone flap defect utilizing computer-assisted 3D modeling and printing.

Modified Bilateral Pi Craniectomy Technique for Reduction Cranioplasty: Novel Technique.

Severe hydrocephalic macrocephaly can cause significant morbidity in infants due to positioning difficulties, skin breakdown, and poor cosmesis. Many surgeons over the past decades have described a variety of surgical techniques of reduction cranioplasty. In this article, the authors describe a novel technique for skull reduction cranioplasty with modified bilateral Pi craniectomy.

Hydroxyapatite ceramic implants for cranioplasty in children: a retrospective evaluation of clinical outcome and osteointegration.

Cranioplasty in children is a controversial and challenging issue, since there is still no consensus on the ideal material. Main problems in paediatric age are represented by the child's growing skull, the lower bone thickness and the high incidence of cerebrospinal fluid (CSF) disorders or brain swelling. Autologous bone is still considered the "gold standard". When it is not available, a wide range of alloplastic materials have been proposed. Hydroxyapatite, a ceramic-based derivative, bears a chemical co...

Cranioplasty in infants less than 24-months of age: a retrospective case review of pitfalls, outcomes, and complications.

Management of pediatric skull defects after decompressive craniectomy (DC) poses unique problems, particularly in children younger than 24-months. This includes complications including resorption and infection as well as difficulties with plagiocephaly and reconstruction. The goal of this study is to evaluate bone resorption complications after cranioplasty in patients

Retrospective chronologic CT analysis of bone flap fusion and resorption after craniotomy and autologous cryopreserved cranioplasty.

In open brain surgery, fixation of the bone flap is the final procedure. The bone flaps then fuse naturally. The objective of this study was to investigate the chronological process of bone fusion after craniotomy and autologous cranioplasty.

Autologous Bone Cranioplasty: A Retrospective Comparative Analysis of Frozen and Subcutaneous Bone Flap Storage Methods.

The use of autologous bone for cranioplasty offers superior cosmesis and cost-effectiveness compared to synthetic materials. The choice between two common autograft storage mechanisms - subcutaneous versus frozen - remains controversial and dictated by surgeon preference.

From decompressive craniectomy to cranioplasty and beyond-a pediatric neurosurgery perspective.

Decompressive craniectomy (DC) is an established neurosurgical emergency technique. Patient selection, optimal timing, and technical aspects related to DC and subsequent cranioplasty remain subjects of debate. For children, the overall degree of evidence is low, compared with randomized controlled trials (RCTs) in adults.

Risk of Complications in Primary Versus Revision-Type Cranioplasty.

Cranioplasty (CP) is a multifaceted procedure in a heterogenous patient population, with a high risk for complication. However, no previous large-scale studies have compared outcomes in primary (ie, first attempt) CP versus revision CP (ie, following previous attempts). The authors, therefore, analyzed long-term outcomes of 506 consecutive primary and revision CPs, performed by a single surgeon.

Progressive Scalp Thinning Over Mesh Cranioplasty and the Role of Lipotransfer.

To evaluate the role of lipotransfer in progressive scalp thinning following titanium mesh cranioplasty.

Cosmetic and Neuroprotective Placement of a Custom-made Ultra-high-molecular-weight Polyethylene Cranial Plate (SKULPIO®) in Single-step Surgery: A Technical Note and Case Report.

Cranioplasty is a common procedure in neurosurgery. However, cosmetic and neuroprotective reconstructions are necessary following cranioplasty. Treatment of patients with a meningioma with bone infiltration requires the removal of the tumor-infiltrated bone and subsequent cranioplasty. We report an efficient technique for cosmetic and neuroprotective reconstructions using a custom-made ultra-high-molecular-weight polyethylene cranial plate (SKULPIO®, Kyocera Medical, Kyoto, Japan) in a single-step surgery ...

Rescue Craniectomy With Subsequent Cranioplasty for Recurrent Symptomatic Subdural Hematoma in the Elderly.

Recurrent subdural hematoma (SDH) is commonly encountered in clinical practice. Multiple surgical techniques have been reported for the management of recurrent SDH with variable success and complication rates. We report an alternative technique to halt SDH re-accumulation in elderly patients with multiple recurrences despite multiple surgical evacuations via rescue craniectomy and subsequent cranioplasty.

An investigation of factors associated with the development of postoperative bone flap infection following decompressive craniectomy and subsequent cranioplasty.

After a decompressive craniectomy (DC), a cranioplasty (CP) is often performed in order to improve neurosurgical outcome and cerebral blood circulation. But even though the performance of a CP subsequent to a DC has become routine medical practice, patients can in fact develop many complications from the surgery that could prolong hospitalization and lead to unfavorable prognoses. This study investigates one of the most frequent complications, bone flap infection, in order to identify prognostic factors of ...
