Rinne and weber test:

[neha_subh]

Q:
Rine test: vibrating tuning fork used, when it placed on the left mastoid bone pt.apreciate it as louder, while softer when it is placed near left extrnal auditory meatus.
weber test: same vibrating tuning fork when placed on mid of forhead he beter apreciate in left ear than the right,
this pt.lost hearing in which ear and which type conducting or sensorineural?

first give me answr of this question then pls explain lil bit about weber test :sorry:

left conductive hearing loss

[warfarin90]

In Weber test we strike tuning fork and place it in the middle of forehead and ask pt. if he can hear equal on both sides... (by placing it in the middle we are testing bone conduction)...if pt. has normal air conduction (doesn't have conductive hearing loss) in both ears, then pt. can hear tuning fork equally in both ears. However, if patient has conductive hearing loss, say in left ear, then since there is no air conduction... bone conduction will be increased and Weber will localize to the left ear.

Similarly, if there is sensorineural hearing loss, say in right ear, bone conduction will be decreased in that ear and Weber will localize to left ear because bone conduction is fine in left ear.

Hope I made some sense.

ya you are right,
this patient has left ear conductive hearing loss..
thanks
