An Otoscope is a medical apparatus, 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 visualize the outer ear and middle ear. Otoscope consists of a handle and a head. The head contains an electric light source and a low power magnifying lens. The front end of the otoscope has an attachment for disposable plastic ear speculums. The examiner first straightens the ear canal by pulling on the pinna and then inserts the ear speculum side of the otoscope into the external ear. The examiner can then look through a lens on the rear of the instrument and see inside the ear canal.
