UPDATE
What is the function of contralsteral masking is(2) - Answer- 1)Validate White noise
masking being present at the appropriate intensity.
2) Better ID WV
White noise making Prevents - Answer- Bone conducted cross over
What is the function of White noise Making - Answer- It prevents Bone Conducted
Cross over.(Vibration)
What methods(2) are used to improve better ID of WV - Answer- 1)You Stimulate
Contrlateral Ear
2)Turn down Stimulation Intensity 4-5 Split is more pronounced
If you don't use White Noise Masking you get a - Answer- False Negative. Responses
appear intactand unchanged however Patient has hearing loss post op.
False Negative - Answer- Data is good, Patient is bad post Op.
3 Types of Hearing loss are contingent on location - Answer- 1. Conductive
2 Sensorineural
3 Retrocochlear
If you have conductive problem its also called a - Answer- Peripheral Problem
Conductive /Peripheral Problem Changes in BAEP - Answer- Increase in Absolute
Latency and Normal Interpeak
If you have a conductive problem; peripheral hearing loss. Youll have an.. - Answer-
Increase in Absolute Latency and Normal Interpeak WI,111,V.
1.4,3.4,5.5 Absolute.
2.0,2.0,4, Interpeak.
,If you have a problem of hearing up to the cochlea - Answer- You'll have conductive
hearing loss
Sensorineural is also called __ Problem - Answer- Cochlear
Sensorineural the problem is at the - Answer- At the Chchlea
If you have a problem with Sensorineural Youll see a change in BAEPS in - Answer-
Normal or Near normal at high click.( Talking loud)
At lower click intensities you'll have an increased in absolute latency and normal
interpeak. Will be shifted out.
Retrocochlear the problem is after the - Answer- Cochlea. Interpeaks abnormal
Retrocochlear is also called and involves the - Answer- Central , Brainstem
Retrocochlear you get a change in BAEPS IN - Answer- Increase In interpeak. WI-III
OR III-V AND I-IV. interPeaks.
When it is at the 8th CN, Pons, or Midbrain.
IF you have a problem with Auditory ossicles what would be your abnormality ? -
Answer- Increased in ABSOLUTE lateny
Interalpeak defines the - Answer- Central, Brainstem, 8th cn
Absolute Defines - Answer- Peripheral
If you have a problem at your Midbrain the Abnormality would be - Answer- Interpeak,
8th n Brain.
Kinked Earphone Tubing (Crani)- Problems with BAEP include, Becuase they can Kink
your ubing. The sounds comes up the tubing and has a phone tip in the ear. If Kinked it
decreased the sound intensity. - Answer- Increase in Absolute Latency and Normal
interpeak latencies.
Blood, Betadine or Irrigation Fluid got into Tubing. Fluid get into tube and fill the Tube.
The intensity of the sound decrease. You see a change in BAEPA BY - Answer-
Increase in Absolute Latency and Normal interpeak latencies.
If you have excessive Earwax is also called - Answer- Cercumen
If you have excessive Earwax youll see a change in BAEP by - Answer- Increase in
Absolute Latency and Normal interpeak latencies.
Perforated or Hardened Typanic Membrane - Answer- Increase in Absolute Latency and
Normal interpeak latencies.
Will not have Interpeak Problems till - Answer- CN 8
If its before Wave I It's anything choclea middle ear external ear is - Answer- Increased
in Absolute Latency. Has to be!
In Middle ear; Ossicles is a structure Mallus incus and stapes and estaution tube. If you
have an Middle Ear infection what would you call that - Answer- Otitus Media( Middle)
So if the patient has Otitus Media you'll see a change in BAEP in - Answer- Increased in
Absolute latency and Normal Interpeak Latencies.
Artifical Ventilation(Us breathing for the patient.) Can cause pressure Ventilation in
middle ear. How would it change in BAEP? - Answer- Increased in Absolute latency and
Normal Interpeak Latencies
Otosclerosis(Middle Ear) Bony Ca+ on Stapes - Answer- Increased in Absolute latency
and Normal Interpeak Latencies

Neve is monitored. - Answer- Cholesteatoma:
Mastoidectomy What modality to monitor in surgery and whats at Risk - Answer- CN VII
RISK.
Hearing loss and Facial Nerve.

High Frequency Hearing Loss_- Inner Ear Cochlea. Sensorineural(Chochlear). only
option two would work! - Answer- Normal or near at the high intensity click stimulation ,
but at lower intensity stimulation, Increased absolute latencies and Normal interpak
latenices.
Normal at 85dB
Abnormal at 65dB
High Frequency Hearing Loss Inner peak Broad Band Clicks in the __ to __ range -
Answer- 2,000-4.000 Range of Frequency, these exact frequencies are affected with
High frequency loss.
Presbycusis Inner Ear Cochlea only option two would work. Aging population - Answer-
Normal or near at the high intensity click stimulation , but at lower intensity stimulation,
Increased absolute latencies and Normal interpak latenices.
Acoustic Neuroma/ Vestibular Schwannoma: Retrocochlear
Note NC8 is the Bridge between WII-III - Answer- Increased I-III, Increased I-V
interpeak
Neurofibromatosis Type II- Hearing Loss - Answer- Tumors Grow in the Brain. Have
Acoustic Neuroma/ Vestibular Schwannoma. on BOTH side. So you have
