As the eardrum is the border between the external ear canal and the middle ear, its characteristics can indicate various diseases of the middle ear space. [citation needed] Otoscopic examination can help diagnose conditions such as acute otitis media (infection of the middle ear), otitis externa (infection of the outer ear), [citation needed ...
The cone of light, or light reflex, is a visible phenomenon which occurs upon examination of the tympanic membrane with an otoscope. [1] Shining light on the tympanic membrane causes a cone-shaped reflection of light to appear in the anterior inferior quadrant.

The ears are arguably one of the most important features of the human body. They allow us to hear the world around us every day, but that’s not all. Inside our ears is a complex structure that ...

The mirror is worn over the physician's eye of choice, with the concave mirror surface facing outwards and the hole directly over the physician's eye, providing ...
After an otoscopy (examination of the ear with an otoscope) to ensure that the path to the eardrum is clear and there is no perforation, the test is performed by inserting the tympanometer probe in the ear canal. The instrument changes the pressure in the ear, generates a pure tone, and measures the eardrum responses to the sound at different ...
The ear canal volume indicates whether a perforation in the eardrum (tympanic membrane) may be present. The middle ear pressure indicates whether any fluid is present in the middle ear space (also called "glue ear" or "otitis media with effusion"). Compliance measurement indicates how well the eardrum and ossicles (the three ear bones) are moving.
Direct examination of the external canal and tympanic membrane (ear drum) with an otoscope, a medical device inserted into the ear canal that uses light to examine the condition of the external ear and tympanic membrane, and middle ear through the semi-translucent membrane.
