Otoscope

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.

Uses

Because the eardrum is the border separating the external ear canal from the middle ear, its characteristics can give the healthcare professional a lot of information about what's happening on the other side of the eardrum.

Types

There are two types of otoscopes: pocket otoscope and standard otoscope. The pocket otoscope has a handle that uses batteries to light the viewing instrument. The standard otoscope is larger, has a cord, and is plugged into a wall for power.

Components

The otoscope consists of a handle and a head. The head contains a light source and a simple low-power magnifying lens, typically around 8 diopters (3x).
