Hey , do you know answers to these questions?

In Weber's test,
in conductive deafness, sound will be lateralised towards diseased
ear why?
acute suppurative otitis media ,why there will be pain at night?

hoping to get answers soon.

The way I understood it, in Weber's Test, in a patient with conductive hearing deficit, the sound is lateralized to the diseased ear b/c there is less opposing background "noise" getting through as opposed to the ear that has no conductive blockage. In a patient with sensorineural hearing loss, sound lateralizes to the healthy ear.

In Rinne's Test, in a normal ear air conduction>bone conduction. In a patient with conductive hearing loss bone conduction> or equal to air conduction b/c of the conductive blockage. In a patient w/ sensorineural loss, air conduction>bone conduction just like a healthy ear.

ok i agree with your opinion regarding lateralisation of sound towards diseased ear in case of conductive deficit, in Weber's test.
But why sound will be lateralised towards the healthy ear in Rinne's test??

There is no lateralization in Rinne's test. You test each ear separately for bone conduction (tuning fork on mastoid process) vs air conduction (end of fork right outside ext. auditory canal).

thanks for your answer
