Abstract
-Narrow Band Imaging is an optical endoscopic technique used for visualising the vascularisation of the framed structures; -The application of this tool to the otoendoscopy is not yet widespread; -We have used NBI to visualize the vascular patterns of middle ear masses; -Paraganglioma showed a quite distinct appearance compared to aural polyp; We suggest that NBI should be considered in the diagnostic work-up of middle ear masses.
