Audiology Remediation-Jayme Monroe

Front 1

Otosclerosis

Back 1

Common cause for conductive HL. Spongy growth on stapes footplate

Front 2

Myringotomy

Back 2

Surgery performed for chronic OME. Small incisions are made to the tympanic membrane to relieve pressure.

Front 3

Ranges of hearing loss

Back 3

Normal: Up to 15 dB
Mild: 16 dB to 40 dB
Moderate: 41 dB to 55 dB
Moderate-Severe: 56 dB to 70 dB
Severe: 71 dB to 90 dB
Profound: 91+ dB

Front 4

Conductive Hearing Loss

Back 4

Efficiency of sound conduction is diminished. Inner ear, acoustic nerve and auditory centers are normal. Conductive hearing loss is NEVER profound because bone conduction still occurs.

Front 5

Hearing Level

Back 5

The lowest intensity of sound necessary to stimulate the auditory system.

Front 6

Cerebellopontine Angle

Back 6

Where the auditory nerve exits the temporal bone and enters the brainstem

Front 7

What are the 2 branches of the vestibulocochlear nerve (CN VIII)?

Back 7

Vestibular and auditory/acoustic

Front 8

What are the 2 systems of the Inner Ear?

Back 8

Vestibular and cochlear

Front 9

Which cranial nerve innervates the stapedius?

Back 9

CN VII (Facial)

Front 10

Which cranial nerve innervates the tensor tympani?

Back 10

CN V (Trigeminal)

Front 11

Type C Tympanogram result

Back 11

The point is below -100 daPa

Front 12

Type B Tympanogram result

Back 12

No point. The middle ear is filled with fluid, possibly due to cerumen impaction.

Front 13

Type Ad Tympanogram result

Back 13

Point is at 0 but the peak is abnormally high or disconnected

Front 14

Type As Tympanogram result

Back 14

Point is at 0 but it is shallow

Front 15

Type A Tympanogram

Back 15

Normal. The point is at 0 dB and the shape is a large V.

Front 16

2 ways to conduct vestibular testing

Back 16

ENG/VNG: Measure eye motion with electrodes to measure presence of dizziness

Posturography: Test of balance

Front 17

Rollover Test

Back 17

Used to determine if there is severe cochlear distortion or retrocochlear involvement by repeating MCL at much louder levels. A decreased score means retrocochlear involvement.

Front 18

Purposes of Suprathreshold tests

Back 18

To determine how good residual hearing is
To be used as an indicator of prognosis for hearing aids
Screening for retrocochlear pathologies

Front 19

Threshold vs. Suprathreshold

Back 19

Threshold: Aims to find the lowest level of speech detected.

Suprathreshold: Determines how well a person understands what is heard once it is made audible.

Front 20

Word Recognition Test (WRT) aka Speech Discrimination

Back 20

Familiar 1-syllable words are given at different intensity levels. Loudness level and words are given, then the percentage of words correct are calculated

Front 21

Spondee Threshold or Speech Recognition Threshold (SRT)

Back 21

Threshold of recognition of familiar, two-syllable words with equal stress on each syllable. Threshold is the lowest intensity with at least 50% accuracy. Threshold should be within 10 dB of pure tone average

Front 22

Speech Awareness Threshold (SAT)

Back 22

Threshold of detected speech. Usually 10 dB lower than ST and PTA.

Front 23

Operant Audiometry

Back 23

Conditioning voluntary responses to sound stimuli for audiometric assessments

Front 24

Electrophysiological Audiometry

Back 24

An objective measure of auditory mechanism functioning. In response to a sound, the cochlea, acoustic nerve and auditory centers generate measurable electrical impulses, called Auditory Evoked Potentials.

Front 25

Signature of noise induced HL

Back 25

On an audiogram, a drop around 4000 Hz, also known as 4k Hz Notch. Usually occurs bilaterally but not always symmetrical.
