The term scutum derives from the Latin word for shield: the scutum in the ear is a sharp bony spur formed by the superior wall of the external auditory canal and the lateral wall of the tympanic cavity.
The scutum forms the lateral margin of Prussak's space and it is usually the first bony structure to be eroded by the enlarging cholesteatoma.
