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 ™

25
Morphology: _____ latencies + ____-____ latencies
peak inter-peak
26
ABR uses ____ or ____
clicks or tones
27
What are the 3 advantages for click ABR
Brief stimuli and produce synchronous neural firings that create clear waveforms useful in neurologic assessment has broad frequency response useful in hearing screening
28
what are 3 disadvantages to click ABR
Not frequency specific consistent with behavioral hearing from 1000-4000 Hz May miss low-frequency HL
29
Advantage of tone ABR
provides frequency-specific information
30
What are the 2 disadvantages of tone ABR
Clarity of ABR is compromised Each frequency has to be tested separately for each ear, so it is a long test
31
When do we use ABR in a neurologic assessment
ABR is most sensitive auditory test of retrocochlear pathology
32
Overall advantages of ABR (6)
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
Overall disadvantages of ABR testing (4)
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
An ASSR is an ______ potential recorded with _______ (steady-state) amplitude and/or frquency-modulated tones or "_____"
evoked continuous chirps
35
ASSR is used to estimate hearing ______
threshold
36
ASSR is _____ than ABR; stimulates 4 frequencies & both ears at once
faster
37
ASSR can be used to estimate ________ ______ even in ______ to ______ HL (ABR cannot)
hearing thresholds severe to profound HL
38
ASSR does not estimate hearing thresholds as well for _____ HL or ______ hearing
mild normal
39
MLR has _____ potentials than ABR & provide information on ______ _____ in _____ regions of auditory system
later auditory status higher
40
MLR is useful in ______ ______ processing assessment, espicially when behavioral measures ___ conclusive
central auditory not
41
OAEs are ____-level sounds emitted by the ______
low cochlea
42
OAEs are related to the _____ function of the cochlea
OHC
43
There are 2 methods of OAEsnused clinically they are:
TEOAE (clicks) DPOAE (2 pure tones) better
44
When will OAEs be abnormal or absent?
with a HL > 25-30 dB HL any degree of CHL
45
What is the limitation with OAE testing
If the problem is beyond OHC the test will not pick this up
46
what are the 6 advantages to OAE testing
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
List the 2 disadvantages of OAE testing
Not useful to predict hearing thresholds only provides information on auditory function up to OHCs in the inner ear
48
When are auditory processing tests recommended?
When central auditory processing disorder (C) APD suspected
49
are there any reference standard for diagnosing (C) APD
No
50
List the battery series of tests recommended within an evaluation for auditory processing tests
temporal processing dichotic listening 'monaural low- redundancy speech perception Binaural function (interaction)
51
Consider an individual's __ and/or _______ status when choosing behavioral tests of central auditory function as well as potential variability in performance in young children due to factors such as response demands and task complexity
age developmental
52
Many pathologies affect both _____ and ____ fucntion
auditory vestibular
53
(electro)physiologic tests for the vestibular system include: (5)
Electrocochleography (ECochG) (Video)Electronystagmography (V/ENG) Rotation Chair Testing Posturography Vestibular Evoked Myogenic Potential (VEMP)
54
Romber test patient is asked to stand with feet _____, arms to ____, first _____ open then _____
together side eyes closed
55
Tandem Gait Test patient asked to _____ heel to ___
walk toe
56
Fukuda Stepping Test Patient asked to ____ in place with eyes ____ for ____ steps
march closed 100
57
edema
swelling
58
ottorhea
discharge/drainage
59
Erythema
redness of the skin or mucous membranes
60
Otalgia
Ear pain
61
Aids (HIV) testing is used to detect the presence of the human __________ virus in _____, _____, or urine
immunodeficiency blood saliva
62
What is a Biopsy
Removal of a sample of tissue from the body for analysis
63
Medical _____ plays a crucial role in otologic diagnosis of congenital abnormality of _______ bone
imaging temporal
64
What substance is used to obtain radiographic images
contast dyes (usually iodinated) and they are injected into the body usually via vein in order to better define stucturs
65
CAT or CT scans uses special X-ray equipment to produce ______ images of the ______ of the body & a computer to join together in cross-sectional views of the area being studied
multiple inside
66
An MRI uses a powerful _____ field, _____ waves, and a ______ to produce detailed images of organs, soft tissue, bones of internal body structures
magnetic radio computer
67
MRI can pick up acoustic tumors as small as _ mm
