BACKGROUND Cranioplasty is a standard neurosurgical procedure which is performed after decompressive craniotomy. Fatal complications associated with this procedure are not well documented. Here, we report a case of fatal cerebral swelling after cranioplasty and discuss the possible mechanism of this complication. CASE DESCRIPTION A 64-year-old man was admitted with the diagnosis of cerebral h...

Background Craniectomies and cranioplasty are common neurosurgical procedures performed after brain trauma, ischemia, tumor resection, or infection. Post-cranioplasty autologous bone flap resorption may occur in patients after delayed cranial reconstruction. The occurrence is usually low when bone flaps are stored in subcutaneous abdominal tissue. We report a unique case of post-cranioplasty cr...

OBJECTIVE Cranioplasty using a cryopreserved skull flap is a wide spread practice. The most well-known complications of cranioplasty are postoperative surgical infections and bone flap resorption. In order to find biological evidence of cryopreserved cranioplasty, we investigated microorganism contamination of cryopreserved skulls and cultured osteoblasts from cryopreserved skulls. METHODS Cr...

This case report discusses a case of aseptic osteonecrosis in a cranioplasty bone flap after decompressive craniectomy, which is a known, but rare complication after autologous cranioplasty. We suggest that the pathophysiology of cranial bone flap necrosis may have a similar pathophysiology to free flap necrosis/failure. The key suggested problem causing the osteonecrosis is vessel thrombosis w...

autologous bone is considered the first choice as material of cranioplasty because of its biological and anatomical features. however in some situations such as skull fractures or tumors the bone flap is not available or it must be replaced with a heterologous cranioplasty because of the development of surgical complications. authors of this study aimed to identify which are the best materials ...

Background: Cranioplasty (CP) is a neurosurgical procedure performed after decompressive craniectomy using autologous bone graft or various artificial materials. Aim: To find differences in complications between patients who underwent CP an flap versus titanium mesh as well to identify significant risk factors for post-CP Study Design: Comparative cross-sectional study. Methodology: A total of ...

BACKGROUND In cranial reconstruction, the features of artificial bone differ. Custom-made porous hydroxyapatite (HAp) implants for cranioplasty have been used all over the world because of their good cosmetic, biocompatibility, and osteoconductive properties. Surgical techniques were analyzed, and histological assessment of new bone formation in the hydroxyapatite was performed. METHODS Over ...

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 ...

Decompressive craniectomy is an established procedure to lower intracranial pressure and can save patients' lives. However, this procedure is associated with delayed cognitive decline and cerebral hemodynamics complications. Studies show the benefits of cranioplasty beyond cosmetic aspects, including brain protection, and functional and cerebrovascular aspects, but a detailed description of the...

Polymethylmethacrylate (PMMA) cranioplasty procedures were performed on 20 patients over a 2-year period. Nine of these patients had a total of 17 CT examinations, performed when clinically indicated. On 16 of the 17 CT scans, the appearance of the cranioplasty plate was characteristic of plates with gas bubbles. The appearance of these bubbles was stable over an extended period of time, ruling...
