Osteomyelitis is an inflammatory condition of bone involving the medullary cavity, the Haversian system, and the adjacent cortex. According to literature review osteomyelitis of zygomatic bone secondary to the depressed fracture of the parietal bone never reported. Here we report a case of osteomyelitis of zygomatic bone which develops 3 month after the depressed fracture of parietal bone.

The mammalian skull vault consists mainly of 5 flat bones, the paired frontals and parietals, and the unpaired interparietal. All of these bones are formed by intramembranous ossification within a layer of mesenchyme, the skeletogenic membrane, located between the dermal mesenchyme and the meninges surrounding the brain. While the frontal bones are of neural crest in origin, the parietal bones ...

Background: In several conditions we have face cranial bone defects. Reconstruction of these defects remains one of the most challenging problems encountered by craniofacial surgeons. Objective: To evaluate bone repair in cranial bone defects by use of an implant made of octacalcium phosphate in combination with bone matrix gelatin (OCP/BMG). Methods: We used 40, 5–6-week-old male Sprague-Dawle...

Bone metastases from prostate cancer are very common. They are usually located on the axial skeleton. However, cranial bone metastases especially to the parietal bone are rare. We report a case of metastatic prostate cancer presenting with left parietal bone metastasis in a patient with no urological symptoms or signs. We should consider prostate cancer in any man above 60 years presenting unus...

BACKGROUND As a culmination of efforts over the last years, our knowledge of the embryonic origins of the mammalian frontal and parietal cranial bones is unambiguous. Progenitor cells that subsequently give rise to frontal bone are of neural crest origin, while parietal bone progenitors arise from paraxial mesoderm. Given the unique qualities of neural crest cells and the clear delineation of t...
