Calvarial bones arise from two embryonic tissues, namely, the neural crest and the mesoderm. In this study we have addressed the important question of whether disparate embryonic tissue origins impart variable osteogenic potential and regenerative capacity to calvarial bones, as well as what the underlying molecular mechanism(s). Thus, by performing in vitro and in vivo studies, we have investi...

Secondary aneurysmal bone cyst in fibrous dysplasia is exceedingly rare, especially in the skull and particularly in the frontal bone. We present a case of aneurysmal bone cyst concomitant with fibrous dysplasia in the frontal bone in a 15-year-old male patient presenting with headache and euphoria with an uncharacteristic imaging appearance and treated successfully by total resection.

A 10-year-old girl presented with an episode of seizure following oste omyelitis of the frontal bone and subperiosteal abscess due to frontal sinusitis. CT scan confirmed osteomeyelitis of the frontal bone and subperiosteal abscess. At surgery, the subperiosteal abscess and contiguous subdural abscess was drained and sequestrectomy of the affected frontal bone done. Broad spectrum antibiotics a...

INTRODUCTION Despite impressive advances in endoscopic approaches to the frontal sinus, the osteoplastic flap approach to the frontal sinus remains an important tool for surgically treating frontal sinus pathology. In this approach, the anterior table of the frontal sinus is opened wide while maintaining a hinged attachment to the overlying periosteum and soft tissue along its inferior border. ...
