Abstract Introduction: external nasal walls are  an important factor  in the drainage or obstruction of the ostiomeatal complex, therfor  anatomical variations in the nasal cavity can elevate the risk of pathological sinus conditions. The aim of this study is to evaluate anatomical variations of paranasal sinuses and nasal cavities using cone beam computed tomography (CBCT). Materials and ...

THE existence of an electrical potential in the vertebrate eye, with the cornea positive to the fundus, was demonstrated over a century ago (Du Bois-Reymond, 1849). This potential, the standing or corneo-fundal potential, is often described as a steady potential to distinguish it from the rapidly oscillating potential of the electroretinogram. It is not, however, a truly steady potential, but i...

Imaging of peripheral joints is a simple and valu able technique for evaluating joint disease in adults (1-12). It has been shown to be a sensitive index of inflammatory activity, occasionally revealing synovitis before the roentgenogram, laboratory studies, or even physical examination is positive (1-13). These studies document the presence and location of inflammed synovium and reflect progre...

The aim of this study is to measure the ischiofemoral distance (IFD) in the normal hip with healthy surrounding soft tissues and describe its variations caused by gender, age and proximal femoral anatomy so that this could serve as a reference for future studies on this subject. This is a retrospective study in which we reviewed the CT scans of 149 patients (298 hips) who had a CT of their pelv...
