Vestibulocochlear

Question 1

Testing hearing

Answer 1

Ask the patient to repeat a number whispered in their ear while you block/cover the other ear

Question 2

What is the Rinne’s test?

Answer 2

Air and bone conduction assessment

Tuning fork is placed on mastoid process of the ear first

Then, compare it held adjacent to the pinna

Repeat for the other ear.

Question 3

What is Weber’s test?

Answer 3

Place tuning fork in the middle of the forehead
sound should be transmitted equally to both ears

In conductive deafness, sound localises to the affected ear in sensorineural deafness the opposite happens.

Question 4

Normal experience for all 3 tests:

Answer 4

1. Whisper is heard in both tests
2. Weber’s is equally loud in both ears
3. Rinne’s : conduction in air is greater than in bone

Question 5

Conductive deafness experience in all 3 tests:

Answer 5

1. Whisper is quieter
2. Weber’s is louder on the same side
3. Rinne’s test, the conduction is louder in bone than it is in air

Question 6

Sensorineural deafness experience in all 3 tests:

Answer 6

1. Whisper is quieter
2. Weber’s is louder on opposite side
3. Rinne’s test, the conduction is reduced in both air and bone

Question 7

What is conductive deafness?

Answer 7

impaired perception of low pitched sounds

can be caused by wax, rupture of tympanic membrane and middle ear pathology

Question 8

What is sensorineural deafness?

Answer 8

reduced perception of high pitched sounds

can be caused by infection, congenital disorders, noise induced disorders, Menieres disease
