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 ear symptoms. An otoscope potentially gives a view of the ear canal and tympanic membrane or eardrum. 

An otoscope consists of a head and a handle. It has a lower powered magnifier and a light. The disposable speculum fits on the end. When examining the patients ear, the physician first must stabilize the otoscope to prevent it from traveling too far into the ear and damaging the ear drum. Pneumatic otoscopes push the speculum into the ear to test the ear drum. Some models are wall mounted with flexible cords, while others are portable and battery operated and usually come with a base so they can be easily recharged. They now also come in several colors and can be found sold in sets with ophthalmoscopes.
