An Otoscope or auriscope is a medical device which is used to look into the ears. Health care providers use otoscopes to screen for illness during regular check-ups and also to investigate when a symptom involves the ears. With an otoscope, it is possible to see the outer ear and middle ear. Today, otoscopic or ophthalmoscopic heads can usually be attached to the base (which supplies the 120 VAC electrical power) or wall-mounted to look at the patient's ears or eyes.
