THE OTOSCOPE

Description : Otoscopes have been produced with small magnifying lenses so that instruments can be introduced through the speculum into the ear canal, with large magnifying lenses that pneumatically seal the speculum so that a Siegle attachment can be used, and with specula of various shapes and materials, both reusable and disposable, imitating the designs of their 19th century predecessors in metal and plastic.
 
Recent developments have included improvements in illumination by means of miniature halogen bulbs which produce a brighter, whiter light, and the introduction of fibreoptic illumination, which brings an even circle of light close to the tip of the otoscope. This, too, is but a modern improvement of Blake's operating otoscope of nearly 80 years ago which used a prism in a similar way.

Modern specula have sponge rubber seals which allow an airtight fit for pneumatic otoscopy.
