How do doctors look in your ear?   They use a device called an otoscope. It has a light source at the tip and a magnifying glass at the back, a disposable sleeve is used, replaced for each patient. What tâ¦he doctor sees when looking in is: The ear canal, and at the end of that the eardrum or tympanic membrane. He looks if the membrane is clear and without holes, and if there is any signs of inflammation, fluid or pus behind the eardrum.
