Sklar's Zoellner ear speculum is a funnel shaped attachment for an otoscope that allows examination of the ear canal and eardrum. The speculum is inserted into the ear canal and the otoscope handle provides a light source and low-power magnification so the practitioner can view the eardrum. Disease and infections of the middle or inner ear can largely be detected by this examination. The aluminum speculum has a oval, tip, available in a variety of diameters.
