BACKGROUND: Cranioplasty of patients with craniosynostosis requires rapid, precise and gentle osteotomy of the skull to avoid complications and benefit the healing process. The aim of this prospective clinical study was to compare two different methods of osteotomy. Piezosurgery and conventional osteotomy were compared using an oscillating saw and high speed drill while performing cranioplasties with fronto-orbital advancement. METHODS: Thirty-four children who required cranioplasty with fronto-orbital advancement were recruited consecutively...

Aseptic bone flap resorption, a rare complication after cranioplasty following decompressive craniectomy, is more likely to develop in children. We experienced two cases of aseptic bone flap resorption and identified potential pathophysiological mechanisms through histological findings. In the first case, an 11-year-old girl underwent decompressive craniectomy due to brain swelling with contusion. An autologous bone flap was cryopreserved for four months. Twenty-five months after cranioplasty with autologous bone flap, aseptic bone flap resorption was observed, and cranioplasty was performed with ceramic bone...

INTRODUCTION: Cranial defects following intra-osseous tumor removal may be large and require adequate reconstruction. CAD/CAM implants have been used for years to achieve an optimal cosmetic result. The disadvantage is that such implants require a second surgery. A preoperative virtual planning of resection margins and the simultaneously fabrication of the cranioplasty could be a possibility to subsume the steps tumor resection and cosmetic restoration to a single procedure. METHODS: We present two cases of patients with complex intra-osseous spheno-orbital meningioma...

Gastrointestinal stromal tumors (GISTs) are rare, but are the most common mesenchymal neoplasm of the gastrointestinal tract. The most common sites of metastasis are liver and peritoneum, while bone metastasis is rare. We report on a patient with skull metastasis after seven years of treatment with imatinib for metastatic GIST. She underwent metastasectomy consisting of craniectomy with excision of the mass, and cranioplasty and continued treatment with imatinib and sunitinib, without evidence of cranial recurrence...

BACKGROUND: Growing skull fractures (GSFs) are rare complications of pediatric head trauma that comprise skull fractures associated with an underlying dural tear and an intact arachnoid membrane. They are often misdiagnosed, and delay in management can lead to progression of the disease along with its neurological sequelae. Multiple clinical reports and qualitative reviews on this entity exist. To our knowledge, this represents the largest clinical review reporting on established techniques in the management of these fractures...

CASE: The authors describe the case of an 8-year-old boy with pansynostosis in the context of Albright's hereditary osteodystrophy (AHO). This condition had lead to raised intracranial pressure (ICP). The elevated ICP was a consequence of the rigid skull impeding brain growth. Therefore, a decompressive cranioplasty was performed successfully, leaving further space for the growing brain. Affection of the central nervous system has been documented in AHO. However, affection of the skull bones has rarely been described in literature...

Cranioplasty is performed with various alloplastic implant materials, each having advantages and drawbacks. High-temperature vulcanizing silicone is used to fabricate cranioplasty implants because of certain beneficial properties. Silicone cranial implants lead to better adaptation with the bone adjacent to the cranial defect than acrylic resin and metal cranial prostheses. This article describes a technique for fabricating cranial implant prostheses using high-temperature vulcanizing silicone material.

Three-dimensional (3D) imaging is an important tool for diagnostics, surgical planning, and evaluation of surgical outcomes in craniofacial procedures. Gold standard for acquiring 3D imaging is computed tomography that entails ionizing radiations and, in young children, a general anaesthesia. Three-dimensional photographic imaging is an alternative method to assess patients who have undergone calvarial reconstructive surgery. The aim of this study was to assess the utility of 3D handheld scanning photography in a cohort of patients who underwent spring-assisted correction surgery for scaphocephaly...

BACKGROUND: Postdecompressive craniotomy defect management following failed prior cranioplastyis challenging. The authors describe a staged technique utilizing free muscle transfer, tissue expansion, and custom polyetheretherketone (PEEK) implants for the management of previously failed cranioplasty sites in patients with complicating local factors. METHODS: Consecutive patients with previously failed cranioplasties following large decompressive craniectomies underwent reconstruction of skull and soft tissue defects with staged free latissimus muscle transfer, tissue expansion, and placement of custom computer-aided design and modeling PEEK implants with a 'temporalis-plus' modification to minimize temporal hollowing...

BACKGROUND: Surgical site infection (SSI) is one of the main complications after craniotomy. The incidence is up to 11% in the literature. The established procedure is debridement, removal of the bone flap and delayed cranioplasty. Delayed cranioplasty has several disadvantages. A promising approach is the immediate titanium mesh implantation at the time of wound revision. We want to report our experience with this technique with regard to outcome measured by reinfection rates and patient satisfaction...

BACKGROUND: Craniotomies for trauma are associated with a significant risk of wound complications. We report a case in which a chronic nonhealing draining sinus was caused by an ectopic epidermal lining deep to the craniotomy bone flap, adherent to the underlying dura. CASE DESCRIPTION: A 61-year-old man was examined for a 3-year-old, nonhealing scalp wound resulting after a traumatic brain injury. His initial surgery consisted of an intracranial hematoma evacuation through a temporoparietal craniotomy; this was complicated by wound dehiscence and a chronic sinus draining clear fluid that did not resolve with antimicrobial therapy...

INTRODUCTION: Decompressive craniectomy can be a life-saving procedure. Later reconstruction of the skull using the stored bone flap ("cranioplasty") is often associated with complications. These complications require new procedures and often result in the reconstruction of the skull using an expensive patient-specific cranial implant. PATIENTS & METHODS: All adult patients who underwent cranioplasty after decompressive craniectomy in the last 10 years in our center were included (74 patients)...
