ear discomfort, red tympanic membranes, or fever alone are NOT specific diagnostic criteria.
The ear flaps, the tympanic membranes, are the two large ' scales ' just behind the jaw-bone.
otic notch, housing the tympanic membrane, is distinctive.
Infrared tympanic thermometers (ITT's) measure the frequency of infrared light emitted by the tympanic membrane.
tympanic membrane could rupture, causing hearing loss.
