oVEMP measure

• saccule

• vestibucochlear nerve

• superior vestibular nerve function

• Inferior vestibular nerve function

What is the resonance frequency of saccule?

• 1000Hz

• 500Hz

• 2000Hz

• High frequency

All asnwers indicate absent cVEMP response except

• Profound SNHL

• Damage in saccule

• CHL

• Vestibular nerve pathology

What the expected results of Superior Canal Dehiscence (SCD)

• low amplitudes and high thresholds of VEMPS.

• elevated threshold VEMPS

• large amplitudes and low thresholds of VEMPS.

• Thresholds are 10dB higher normal levels

Because in the Meniere disease MD the endolymphatic increase its stiffness, we expect that:

• Shift of resonance frequency from 500 to 1000 Hz

• saccular tuning curve no longer has its best frequency response at 500 Hz

• Most affected ears threshold will be identical to least affected ears

• A + B

In REM , The recommended stimulus is ............ with a minimum recording time of ......... seconds.

• ISTS, 10

• ISTS , 6

• White noise , 10

• ICRA , 5

All following tips can be used with Modified Pressure Method with Concurrent Equalisation (MPMCE) Except:

• Ear mold

• Double dome

• Large ventilation ear mold

• Tulip dome

Which of the following is correct about the insertion of prboe tube

• Not touching the surface of the TM, insertion from inter tragal notch

• Within 5 mm to TM to measure high frequency accurately

• Sound transition from narrow sound bore to wider ear canal should avoided

• All are correct

In which stage we measure the magnitude of resonance peak of ear canal

• REOG

• REUG

• REIG

• REAR

While measuring Maximum Output Sound Pressure Level(MOSPL), which stimulus will we use?

• Pure tone

• ISTS

• Warble tone

• Broadband
