Paranasal sinus obliteration in Wegener granulomatosis.
The authors report 14 cases of Wegener granulomatosis in which one or more paranasal sinuses were obliterated by bone. The maxillary antra were involved in all cases, with the other sinuses being affected less frequently. These changes are thought to result from chronic bacterial sinusitis superimposed on the granulomatous vasculitic process. Computed tomography dramatically demonstrated the bone changes, consisting of a combination of sinus wall thickening and trabeculated new bone formation within the sinuses.
