rinnes and webers test

Question 1

what does a Rinne’s and Weber’s test do?

Answer 1

allows differentiation of conductive and SN deafness

Question 2

what do you do in a Rinne’s test?

Answer 2

place tuning fork over mastoid process until sound is no longer heard, followed by repositioning just over external acoustic meatus

Question 3

for Rinne’s, what does a ‘positive test’ mean?

Answer 3

air conduction (AC) is normally better than bone conduction (BC)

Question 4

for Rinne’s, what does a ‘negative test’ mean?

Answer 4

BC > AC ⇒ conductive deafness

Question 5

what do you do in a Weber’s test?

Answer 5

place tuning fork in the middle of the forehead equidistant from pt’s ears, then ask pt which side is loudest

Question 6

in Weber’s, what does it mean when the sound is localised to the unaffected side?

Answer 6

unilateral SN deafness

Question 7

in Weber’s, what does it mean when sound is localised to the affected side?

Answer 7

unilateral conductive deafness

Question 8

Rinne’s: AC > BC bilaterally
Weber’s: midline

interpretation?

Answer 8

normal

Question 9

Rinne’s:
BC > AC in affected ear
AC > BC in unaffected ear

Weber’s:
lateralises to affected ear

interpretation?

Answer 9

conductive HL

Question 10

Rinne’s: AC > BC bilaterally

Weber’s: lateralised to unaffected ear

Answer 10

SNHL
