Pott's Puffy tumor (PPT) is a rare entity characterized by subperiosteal abscess associated with osteomyelitis of the frontal bone. It is usually managed by surgical curettage of the osteomyelitic bone and long-term antibiotic therapy. Balloon catheter dilatation is a new technique which was recently introduced for the treatment of chronic rhinosinusitis. In this article, we present three PPT c...

Subperiosteal bone-bonding devices have been proposed for less invasive treatments in orthodontics. The device is osseointegrated onto a bone surface without fixation screws and is expected to rapidly attain a bone-bonding strength that successfully meets clinical performance. Hence, the device's optimum shape for rapid and strong bone bonding was examined in this study by finite element analys...

The microfocal x-ray unit, a new type of x-ray machine characterised by an extremely small x-ray source, enables great detail to be recorded in the projection radiographs owing to the high object magnification and resolution obtained with this system. Microfocal radiographic examinations were carried out on the wrists and hands of 26 patients with early or moderately advanced rheumatoid arthrit...

Osteoid osteoma is a benign bone tumor of undetermined etiology, composed of a central zone named nidus which is an atypical bone completely enclosed within a wellvascularized stroma and a peripheral sclerotic reaction zone. There are three types of radiographic features: cortical, medullary and subperiosteal. Forty-four patients with osteoid osteoma were studied retrospectively. In plain films...
