The normal tympanic membrane is in the neutral position (neither retracted nor bulging), pearly gray, translucent and responding briskly to positive and negative pressure, indicating an air-filled space.
Is tympanic membrane white?
Myringosclerosis and tympanosclerosis are similar conditions that affect the middle ear, causing the tympanic membrane (eardrum) to appear bright white. The whiteness is due to accumulated calcium deposits.
What is the color of a normal tympanic membrane quizlet?
Using the otoscope, the tympanic membrane is visualized. The color of a normal membrane is: Pearly gray.
What color is a normal ear canal?
Normal: Auditory canal: Some hair, often with yellow to brown cerumen. Ear drum: Pinkish gray in color , translucent and in neutral position.
What does a yellow eardrum mean?
The bubbles and yellow discoloration behind the eardrum indicate middle ear fluid. Those who do diagnostic testing are familiar with the common otitis management and hearing loss aspect of middle ear fluid.
What does a cloudy tympanic membrane mean?
A normal tympanic membrane is translucent (picture 3). By contrast, when there is fluid in the middle ear, the tympanic membrane appears cloudy, yellowish, or opaque. When there is an air-fluid level present, the tympanic membrane appears translucent above and opaque below the line of demarcation (picture 4).
What should an eardrum look like?
Normal: The eardrum is pearly white or light gray, and you can see through it. You can see the tiny bones of the middle ear pushing on the eardrum. You see a cone of light, known as the “light reflex,” reflecting off the surface of the eardrum.
Why does my eardrum look black?
In most people, earwax naturally and regularly exits a person’s ears. However, if this does not happen quickly enough or the glands produce too much earwax, it can build up in the ear canal and become darker.
Who uses an otoscope?

When looking into a patient’s ear with an otoscope the absence of the light reflex may indicate which of the following?
A dull or absent light reflex from the eardrum may be a sign of a middle ear infection or fluid.
What does normal ear canal look like?
In a normal, healthy ear the ear canal appears the same color as the skin and the eardrum is a light gray or pearly white. The eardrum is not bulging outward and should reflect light.
Is the tympanic membrane concave or convex?
Coming from the ear canal the tympanic membrane is concave.
What color is fluid in Eustachian tube?
Normally the Eustachian tube is under our control, however, when congested, the middle ear space becomes a vacuum. The eardrum is pulled backwards and cannot vibrate easily. Hearing suffers, and fluid can be drawn from the tissues lining the space. In adults the fluid is clear and watery and not typically infected.
