BACKGROUND: To date, calvarial defects in dogs have traditionally been addressed with different types of implants including bone allograft, polymethylmethacrylate and titanium mesh secured with conventional metallic fixation methods. This report describes the use of an absorbable and non absorbable novel polymer fixation method, Bonewelding® technology, in combination with titanium mesh for the repair of calvarial defects in two dogs. The clinical outcomes and comparative complication using resorbable and non-resorbable thermoplastic pins were compared...

Reconstructive cranioplasty can be associated with many complications and add to the not insignificant potential risks associated with decompressive craniectomy. In the setting of post-traumatic hydrocephalus, treatment with a ventriculoperitoneal (VP) shunt prior to reconstructive cranioplasty likely increases these risks even further. The authors report a case of a 17-year-old male with a history of a severe closed head injury who initially suffered a life-threatening complication associated with intracranial hypotension after cranioplasty only to succumb to malignant intracranial hypertension following a second cranioplasty attempt...

Professor William Wayne Babcock (1872-1963) is considered as a leading figure of American surgery during early 20th century. He introduced many innovative surgical techniques such as Babcock operation for the treatment of varicose veins, the Babcock-Bacon operation for the treatment of cancer of the rectum and sigmoid colon preserving anal sphincters, the "soup bone" cranioplasty technique, and the nerve disassociation technique for the relief of certain forms of paralysis or parasthesia due to injury or inflammation...

OBJECTIVE Cranioplasty implants should be widely available, low in cost, and customized or easy to mold during surgery. Although autologous bone remains the first choice for repair, it cannot always be used due to infection, fragmentation, bone resorption, or other causes, which led to use of synthetic alternatives. The most frequently used allogenic material for cranial reconstructions with long-term results is polymethylmethacrylate (PMMA). Three-dimensional printing technology has allowed the production of increasingly popular customized, prefabricated implants...

Polymethyl methacrylate (PMMA) has been considered a suitable material for cranioplasty. However, no consensus has been reached concerning the best material for cranioplasty with regard to minimizing complications. Thus, this systematic review and meta-analysis aimed to compare the complication rates of PMMA with those of autologous bone and titanium mesh. This review was registered with PROSPERO (CRD42016042725). Systematic searches were conducted on PubMed/MEDLINE, Scopus, and Web of Science. The focus question was, "Do PMMA prostheses used in cranioplasty have complications rates similar to those of autologous bone and titanium mesh?" A meta-analysis of complication rates was performed on the basis of dichotomous outcomes assessed by risk ratio (RR) with corresponding 95% confidence intervals (CI)...

Decompressive craniectomy is an urgent procedure that is increasingly used for treatment of intracranial hypertension. After recovery, reconstruction of the cranial defect is necessary. Cranioplasty is an elective procedure with a high potential for morbidity if care is not taken on different surgical factors such as the material used as the cranial flap. In Latin America, high costs in some materials used in cranioplasty make its use prohibitive for some patients and institutions, and looking for alternatives has become a priority in neurosurgical centers...

OBJECTIVE In children, the repair of skull defects arising from decompressive craniectomy presents a unique set of challenges. Single-center studies have identified different risk factors for the common complications of cranioplasty resorption and infection. The goal of the present study was to determine the risk factors for bone resorption and infection after pediatric cranioplasty. METHODS The authors conducted a multicenter retrospective case study that included all patients who underwent cranioplasty to correct a skull defect arising from a decompressive craniectomy at 13 centers between 2000 and 2011 and were less than 19 years old at the time of cranioplasty...

BACKGROUND: Currently, various materials are routinely used for cranioplasty after decompressive craniectomy, each with their own features, potential benefits, and harms. OBJECTIVES: To systematically review available literature about safety (infection, resorption, and removal) of different materials used for cranioplasty for any indication. METHODS: A comprehensive search in MEDLINE, EMBASE and the Cochrane library was performed for relevant studies published up to January 2017...

Several surgical options are available for treating the different types of craniosynostosis, including fronto-orbital advancement and remodeling, total or subtotal cranial vault remodeling, barrel stave osteotomy with cranial remodeling, endoscopic suturectomy, monobloc advancement and cranioplasty, and revision cranioplasty. High-resolution, low-dose CT with 3D reconstructed images and volumetric analysis can be useful for evaluating the craniofacial skeleton following surgery. The various types of craniosynostosis surgery and corresponding imaging findings are reviewed in this article...

OBJECT: Patients surviving initial decompressive craniectomy are needed to undergo cranioplasty, which is potentially complicated by postoperative seizures. The definite incidence of post-cranioplasty seizures and application of prophylactic antiepileptic drugs remain controversial. METHODS: We performed systematic review to clarify these issues. Searching through PubMed, Ovid, Web of Science and Cochrane library databases, we included publications recording the incidence of seizures after cranioplasty and prophylactic treatment...

Osteomas are generally benign tumors of the skull that affect all age groups and are diagnosed in the fourth or fifth decade of life, and are rare in childhood. Surgical resection is curative and malignant transformation is very rare. A 12-yearboy who had undergone a craniotomy for resection of a parietal osteoma four years ago, followed by a cranioplasty with methylmethacrylate bone cement, presented to our clinic with an expanding mass overlying the cranioplasty. Upon reoperation, the mass was totally excised, and the parietal cranial defect was repaired using methylmethacrylate bone cement...

Developing a surgical plane between the temporalis muscle and the dura is the most technically challenging step when performing cranioplasty for post-decompressive craniectomy defects. The authors report a simple technique to demarcate this surgical plane by laying a multi-slitted, microporous polyesterurethane (MPU) patch during decompressive craniectomy. Specifically, they tried to avoid creating potential spaces around the patch, which is the inherent drawback of published anti-adhesive techniques. In 21 patients undergoing decompressive craniectomy, and in 11 of them subsequently undergoing cranioplasty, there was no wound related complications...

OBJECTIVE One of the principles of the surgical treatment of craniosynostosis includes the release of fused bone plates to prevent recurrence. Such bone defects require a reossification process after surgery to prevent a cosmetic problem or brain vulnerability to damage. The objective of this study is to describe and analyze the radiological and clinical evolution of bone defects after craniosynostosis. METHODS From January 2005 to May 2016, 248 infants underwent surgical correction of craniosynostosis at HUiP La Fe Valencia; the authors analyzed data from 216 of these cases that met the inclusion criteria for this study...

Three-dimensional (3-D) printing is a method of manufacturing in which materials like plastic or metal are deposited onto one another in layers to produce a 3-D object. Because of the complex anatomy of craniomaxillofacial structures, full recovery of craniomaxillofacial tissues from trauma, surgeries, or congenital malformations is extremely challenging. 3-D printing of scaffolds, tissue analogs, and organs has been proposed as an exciting alternative to address some of these key challenges in craniomaxillofacial surgery...

Background: Cranial defects usually occur after trauma, neurosurgical procedures like decompressive craniotomy, tumour resections, infection and congenital defects. The purpose of cranial vault repair is to protect the underlying brain tissue, to reduce any localized pain and patient anxiety, and improve cranial aesthetics. Cranioplasty is a frequent neurosurgical procedure achieved with the aid of cranial prosthesis made from materials such as: titanium, autologous bone, ceramics and polymers...
