primary non-hodgkin’s lymphoma of the cranial vault is extremely rare. this case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. biopsy revealed a diagnosis of diffuse large b cell lymphoma (dlbcl)...

conclusions along with the technological advancement, different materials are employed according to the size of the cranium defect and the age of the case. the application of split costa cranioplasty for the small cranium defects in the region of patient’s face is the method with the least possibility of complications, and its cosmetic and functional results are quite promising. introduction os...

METHODS: Patients with large cranial vault defects (>50cm) were studied preoperatively and postoperatively (6 months) after cranial vault reconstruction using both: 1) Cognistat Active Form and 2) The FIM instrument (Functional Independence Measure) (n=35). Cranial vault reconstructive techniques varied from split cranial bone to alloplastic implants (PEEK) to titanium implants. Complications, ...

Bones of the cranial vault appear to be highly conserved among tetrapod vertebrates. Moreover, bones identified with the same name are assumed to be evolutionarily homologous. However, recent developmental studies reveal a key difference in the embryonic origin of cranial vault bones between representatives of two amniote lineages, mammals and birds, thereby challenging this view. In the mouse,...

BACKGROUND Historically, surgical treatment of children with a delayed presentation of cranial synostosis required complex cranial vault reconstruction. Recently, less invasive options for surgical correction, such as internal distraction osteogenesis, have been explored. In this study, we describe the successful management of delayed presentation of sagittal synostosis using distraction osteog...

The material properties of cortical bone from the diaphyses of long bones (e.g., the femur and tibia) vary by direction, such that bone is stiffer and stronger along its long axis. This configuration improves the abilities of these structures to resist axial compressive loads coupled with bending. As in long bones, cortical bone from the cranial vault is subject to mechanical loads from various...

An 80-year old woman presented with a 6-month history of enlarging masses involving the left neck and the back of her head. Physical examination showed an 18 cm x 18 cm x 9 cm mass in the occipital region and a 9 cm x 14 cm violaceous mass in the left neck. Computed tomographic scans of the head and body showed a large mass arising from the occipital scalp extending into the parietal area. Ther...

The biocompatible hydroxyapatite cement (HAC) is a welcome alternative to the traditional use of autogenous bone for postoperative corrections of cranial vault irregularities. The authors performed experimental studies to show the safety and osseointegration capacity of HAC on animal models and confirm the osseous replacement without toxic reactions. The purpose of the current study was to anal...
