Q

What is the maneuver otologist use to evaluate the ET function

A

valsalva maneuver ( if there is an intact TM) while TM is observed otoscopically

pt is asked to close mouth, squeeze nostrils tightly while blowing air outward
With normal ET function, ET will open forcing positive pressure in ME space
If ET opens, the TM will appear to balloon outward
Then pt. is asked to swallow, causing the ballooning to disappear as the ET opens to equalize the positive pressure previously created
*other procedure is used with non-intact ™

Q

what are 3 disadvantages to click ABR

A

Not frequency specific

consistent with behavioral hearing from 1000-4000 Hz

May miss low-frequency HL

29
Q

Advantage of tone ABR

A

provides frequency-specific information

30
Q

What are the 2 disadvantages of tone ABR

A

Clarity of ABR is compromised

Each frequency has to be tested separately for each ear, so it is a long test

31
Q

When do we use ABR in a neurologic assessment

A

ABR is most sensitive auditory test of retrocochlear pathology

32
Q

Overall advantages of ABR (6)

A

not affected by sleep , medications

can be used in infants & adults

can be used to estimate hearing threholds

assess auditory neural information up to the brainsteam

widely clinically avaliable

extensive research; considered gold-standard hearing threshold estimation technique

33
Q

Overall disadvantages of ABR testing (4)

A

Test time can be long if conducting tonal hearing estimation

requires prep time

ABR may be absent in sever to profound HL, so may be of limited use in predicting threhsolds for this population

does not assess above brainstem area

interpretation may be very subjective

34
Q

An ASSR is an ______ potential recorded with _______ (steady-state) amplitude and/or frquency-modulated tones or “_____”

A

evoked
continuous
chirps

35
Q

ASSR is used to estimate hearing ______

A

threshold

36
Q

ASSR is _____ than ABR; stimulates 4 frequencies & both ears at once

A

faster

37
Q

ASSR can be used to estimate ________ ______ even in ______ to ______ HL (ABR cannot)

A

hearing thresholds
severe to profound HL

38
Q

ASSR does not estimate hearing thresholds as well for _____ HL or ______ hearing

A

mild
normal

39
Q

MLR has _____ potentials than ABR & provide information on ______ _____ in _____ regions of auditory system

A

later
auditory status
higher

40
Q

MLR is useful in ______ ______ processing assessment, espicially when behavioral measures ___ conclusive

A

central auditory
not

41
Q

OAEs are ____-level sounds emitted by the ______

A

low
cochlea

42
Q

OAEs are related to the _____ function of the cochlea

A

OHC

43
Q

There are 2 methods of OAEsnused clinically they are:

A

TEOAE (clicks)
DPOAE (2 pure tones) better

44
Q

When will OAEs be abnormal or absent?

A

with a HL > 25-30 dB HL any degree of CHL

45
Q

What is the limitation with OAE testing

A

If the problem is beyond OHC the test will not pick this up

46
Q

what are the 6 advantages to OAE testing

A

Not affected by sleep, medications

short test time

no prep time required

can be used in infants & adults

widely clinically avaliable

interpretation is not very subjective

47
Q

List the 2 disadvantages of OAE testing

A

Not useful to predict hearing thresholds

only provides information on auditory function up to OHCs in the inner ear

48
Q

When are auditory processing tests recommended?

A

When central auditory processing disorder (C) APD suspected

49
Q

are there any reference standard for diagnosing (C) APD

A

No

50
Q

List the battery series of tests recommended within an evaluation for auditory processing tests

A

together
side

A

immunodeficiency
blood

Medical _____ plays a crucial role in otologic diagnosis of congenital abnormality of _______ bone

A

imaging
temporal

64
Q

What substance is used to obtain radiographic images

A

contast dyes (usually iodinated) and they are injected into the body usually via vein in order to better define stucturs
