In the weber test: lateralization of the sound goes TOWARD the affected side. what type of hearing deficit is this?
|
conductive deficit
The sound goes toward the "bad ear"s, since it hears bone conduction better than air conduction. |
|
In the weber test: lateralization of the sound goes AWAY from the affected side. what type of hearing deficit is this?
|
unilateral sensorineural deficit
The sound goes away from the side of the sensorineural loss and the "good ear" hears better |
|
Right ear: Rinne (+)
Left ear: Rinne (-) Weber test reveals lateralization to left ear. What is the deficit? |
Right ear: SC>BC
Left ear: BC>SC lateralization of sound goes toward the affected side Left conductive deficit |
|
Right ear: Rinne (+)
Left ear: Rinne (+) Weber test reveals lateralization to right ear. What is the deficit? |
Right ear: SC>BC
Left ear: SC>BC lateralization of sound goes toward the affected side with vestibular problems. Righ sensorineural deficit |
|
Purpose of the Weber test?
|
compare bone conduction and to clarify rinne test results.
|
|
What does a Rinne negative test indicate?
|
conductive ear loss
|
|
Can you are rinne postive in both ears, can you still have hearing loss?
|
Yes, you can have a sensorineural hearing deficit. The weber test could show laterization to one ear.
|
|
what test would you do to confirm the Rinne test and when would you do this?
|
Weber test. to confirm Rinne results, and check for a sensorineural hearing deficit.
