Disorders
Disorder of the outer ear in which the pinna is absent.
What is aural anotia?
Gives us an objective indication of how the conductive mechanism is physically functioning, provides evidence to help us distinguish between sensorineural and conductive losses.
What is a tympanogram?
A bilateral high frequency sloping sensorineural hearing loss, poor speech discrimination
What is presbycusis?
The presence of these results in an amplitude that is at least 6 dB above the noise floor.
What are OAEs?
This pattern shows no indication of outer and/or middle ear pathology. Shows normal hearing or a sensorineural loss.
What is type A?
Separation of bones in the middle ear, causes a conductive loss.
What is ossicular disarticulation?
Define/explain what an auditory brainstem response is and what information we learn from it.
What is is an objective assessment with three major waves or components being I, III, IV, is an auditory response (8th nerve and above) to an electronic stimulation, is an indirect measure of hearing sensitivity?
Define pseudohypacusis.
What is a false hearing loss?
An unexplained discrepancy between the SRT and PTA is the first symptom of this kind of hearing loss.
What is nonorganic hearing loss?
This pattern has a peak pressure outside the normal range. Suggests significant negative middle ear pressure.
What is type C?
Appears as a mass behind the tympanic membrane, fixates on the ossicular chain, a disorder of the middle ear.
What is cholesteatoma?
Two primary clinical uses of ABR.
What is estimating hearing threshold and neurological assessment of auditory pathway?
Define sensorineural hearing loss and its characteristics.
What is
Usually permanent, can fluctuate in severity, cannot be treated medically or surgically, reduces volume and clarity of signal, can range from mild to profound, characterized by air and bone conduction thresholds that are equally abnormal, no air bone gaps, damage to the inner ear?
After you identify that a patient has a nonorganic hearing loss, you manage the patient by doing this.
What is letting the patient know that you know and shift the blame on to your shoulders (Do not blame them.)?
This pattern has no peak and essentially no compliance. Signifies that no TM movement can be detected.
What is type B?
The abnormal growth of bone impacting ossicular chain, inherited disease, causes a conductive hearing loss.
What is otosclerosis?
Define/explain transient evoked otoacoustic emissions (TEOAEs) and what information we learn from it.
What is an evoked response from the cochlea to a sound, elicited to a brief stimulation to the cochlea, stimulus is a click, rules out a significantly handicapping hearing loss (moderate or worse)
Hearing loss that has an anatomical, physiological, or metabolic etiology.
What is an organic loss?
A test for pseudohypacusis. Used for cases of unilateral HL. If a listener is presented with the same stimulus in each ear, he or she will only hear the tone in the ear in which it is louder.
What is The Stenger Test?
This pattern has a peak pressure that is within normal and a high degree of compliance. Signifies excessive movement of the TM.
What is type Ad?
Inflammation of the middle ear, usually with accumulation of infected fluid in the middle ear, bulging of the TM, may have effusion, causes a conductive loss
What is otitis media?
Define/explain distortion product otoacoustic emissions (DPOAEs) and what information we learn from it.
What are is an evoked response from the cochlea to a sound, elicited to a complex stimulation to the cochlea, stimulus is 2 puretones, rules out a significantly handicapping hearing loss (moderately severe or worse).
A hearing loss that people fake, sometimes for compensatory reasons in adults and sometimes to get attention in children.
What is malingering?
Name one audiometric clue that suggests a person may be malingering.
What is response variability, SRT and pure tone disparity, no shadow curve for unilateral loss, normal OAEs w/ abnormal pure tone thresholds, 1/2 word response for spondees, bone conduction is worse than air conduction?
This pattern has a peak pressure that is within normal limits and a low degree of compliance. Signifies limited mobility of the tympanic membrane.
What is type As?
