Hartmann Ear Speculum — Small Conical

Hartmann Ear Speculum — Small Conical

Arthur Hartmann’s conical ear speculum, introduced from Berlin in the 1880s, displaced the cylindrical specula of Toynbee and Wilde because the conical taper engages the cartilaginous external auditory canal without abrading the canal walls — and because the wider proximal aperture lets a hand-held illumination source reach the tympanic membrane without the corner shadow that cylindrical models cast. This small-size variant fits the adult canal with a moderately narrow bony portion, and the paediatric canal of older children.

Why conical, why this size

The cartilaginous outer third of the external auditory canal is compliant and tolerates a tapered speculum; the bony inner two-thirds is rigid and bleeds when abraded. A speculum sized too large for the bony canal engages and produces the cotton-bud bleed the patient remembers as the reason not to return for ear examination. The small conical Hartmann sits in the cartilaginous third without engaging the bony canal — the tympanic membrane is visualised through the canal without the speculum advancing into the bone.

Mirror finish

The inner surface is mirror-polished so the operator’s external light reflects to the tympanic membrane; a matt or scratched inner surface absorbs light and produces the dim view that drives operators to push the speculum deeper than the anatomy tolerates.
