Ear test
Alternative names:
otoscope; test for ear infection; test for otitis externa; test for otitis media
Normal values:
The ear canal varies in size, shape, and color. Normally the canal is skin-colored and has small hairs. Earwax may be present which is a yellowish-brown color. The ear drum is a light-gray color or a glistening pearly-white. The small bones of the middle ear usually are pushing on the eardrum membrane like tent poles. The cone of light, (light reflex) should be seen reflecting off the eardrum surface.
What abnormal results mean:
Ear infections are a common problem especially with small children.
Otitis externa (external ear infection) may be present if the ear canal is red, tender, swollen, painful when wiggling or pulling on the outer ear, or if the canal is filled with yellowish-green pus.
Otitis media (middle ear infection) may be present if the light reflex is dull or absent. The eardrum may be red and bulging. Amber liquid or bubbles behind the eardrum are often seen if fluids collect in the middle ear.
In either case, contact the health care provider if any of the symptoms are seen.
