Electro-otoscope is an ear-mirror with light source and magnifying glass. It is also used as an ear-peeper when placed into the external auditory canal.
It is convenient for infants and bedridden patients to examine the subtle lesions which can not be detected by the naked eye. It is especially important in areas where there is no reflective light source of otoscope.
The subjects were sitting in the front seat, with their upper body slightly off, and their heads turned to the opposite side. The examiner concentrates the reflection of the headlamp or frontal mirror on the appropriate position and gently adjusts the head position of the examinee so that the external auditory canal orifice can be adapted to the light. Adults need to pull the ear slightly backward and upward to straighten the ear canal (children need only pull backward and slightly downward) before they can see the deep part. When pulling, pay attention to whether the subject has pain. If there is cerumen in the ear canal, it should be removed. If the whole bottom of the ear canal can not be seen by straightening the ear canal, the appropriate otoscope or otoscope can be placed for careful observation.
