The otoscope ("ear mirror"; from ancient Greek οὖς Gen. ὠτός "ear" and σκοπέω "view") is a device used by the ENT doctor and the hearing aid acoustician for viewing and examining the external auditory canal including the eardrum ( otoscopy ).
A video otoscope is an otoscope with a built-in CCD camera and cold light source , which transmits its images directly to a screen or a video or hard disk recorder. Due to its enlargement, it enables an even more differentiated diagnosis of the eardrum and the external auditory canal .
The otoscope replaced the ear specula that had been described since the 14th century. The ear specula of various sizes that are commonly used today and which are attached to otoscopes were developed in the first half of the 19th century (the French doctor Jean-Pierre Bonnafont is considered to be the inventor ) and made famous by Anton von Tröltsch from 1860 onwards.
