INTERPRETATION OF ABR DEPENDS ON
PROCEDURE
screening
thresholds
neurodiagnostic
frequency
Present stimuli at high enough intensity level that if they have normal hearing, you will be able to
measure an ABR
(a)
Gradually decrease the intensity level of the stimuli and measure the lowest intensity level when an
ABR is present
(a)
A problem in any part of the auditory pathway could affect ABR
true
false
The cone of light is a permanent structure on the tympanic membrane that is present regardless of whether or not an otoscope is shining a light in the ear canal.
true
false
When performing otoscopy, it is very important that the hand holding the otoscope is braced against the person's head.
(a)
Otoscopy includes a visual assessment of the outer ear and tympanic membrane.
true
false
An otoscopic exam should be performed prior to placing anything inside a patient's ear.
true
false
For tympanometry, the ear tip placed in the external auditory canal must create a hermetic seal.
true
false
If the tympanogram results are the following, what type of tympanogram would this be:
Ear Canal Volume = 1.0 ml
Peak admittance = 1.2 ml
Pressure peak = -215 daPa
(a)
If a system (e.g., the middle ear) has low impedance, this means it also has low admittance
true
false
If the tympanogram results are the following, what type of tympanogram would this be:
Ear Canal Volume = 7.0 ml
Peak admittance = no peak
Pressure peak = no peak
(a)
If the tympanogram results are the following, what type of tympanogram would this be:
Ear Canal Volume = 1.0 ml
Peak admittance = 0.7 ml
Pressure peak = -25 daPa
(a)
Immittance measures (i.e., tympanometry and acoustic reflexes) require the use of a probe tone to evaluate admittance.
true
false
if a reflex condition name includes the term "right" this means that the probe tone is always presented to the right ear.
true
false
What triggers the acoustic reflex?
(a)
If there is pathology (a "lesion") in the left inner ear:
The (a) reflex will be affected.
A main difference between TPOAEs and DPOAEs is the type of stimulus used to evoke the emissions.
true
false
OAE's assess the integrity of the auditory pathway up to (and including) the outer hair cells of the inner ear.
true
false
To count as "present" the intensity level of the OAE's has to be greater than the intensity of the noise floor.
~6dB
true
false
The three electrodes used when recording an ABR are: inverting, non-inverting, and ground.
(a)
An ABR can be obtained from stimuli presented by air conduction or by bone conduction.
true
false
Cholesteatoma is a mass in the middle ear space that typically appears blue/red/purple in coloration due to the high degree of vascularization.
true
false
