Association of Cigarette Consumption and Mucosal Thickening in the Paranasal Sinuses on MRI

Cigarette consumption is associated with increased mucosal thickening in paranasal sinuses, with a dose-response association. This thickening may be persistent after quitting smoking. Cigarette smoking may have a more pronounced impact on the sinus mucosa in areas near the primary maxillary ostium, while dental status may be more likely to affect that on the maxillary sinus floor.
