Otoscopy

Looking into the ear canal and at the eardrum

Overview

Otoscopy is the examination of the ear canal and eardrum using an otoscope, a handheld instrument with a light and a magnifying lens, or with a microscope or endoscope in specialist settings. It reveals wax, foreign bodies, inflammation of the canal, and the color, position, and integrity of the eardrum, including fluid or bubbles behind it. Pneumatic otoscopy adds a gentle puff of air to check how freely the eardrum moves. It is the first step in assessing almost any ear complaint and is typically performed before hearing tests or ear impressions.
