The Electric Otoscope (Auriscope)

Description : An electric otoscope must be capable of delivering light of sufficient brilliance to illuminate fully the depths of the external ear canal.

Until recently, the standard source of illumination has been an incandescent bulb mounted axially to allow sufficient light to emanate from the end of the speculum.

This design has two inherent drawbacks: the position of the bulb interferes with instrumentation through the otoscope, and the smallest departure from its optimal position greatly reduces the amount of light emerging from the end of the speculum.

If the instrument is inadvertently dropped or mishandled, the bulb carrier can easily become misaligned and it is hardly surprising that some students of otoscopy experience difficulties when handed an instrument which is incapable of adequately illuminating the ear canal.
