Rinne's weber's

Rinne's:

+ve:    Air conduction > Bone conduction

Normal & Sensory neural deafness

-ve:    Bone conduction > Air conduction

conductive deafness & severe sensory neural deafness( false -ve )

 

Weber's lateralisation:

To  diseased ear : conductive deafness

To better ear:  sensory neural deafness

 

Examples:

1. Test	Rinne's	Weber's
   Rt	-ve
   Lt	+ve	lateralised

Interretation:

Rinne's: Rt  -ve  --> CD/severe SND

If CD then weber's should go for Rt.

If severe SND then for Lt

As weber's is for left : result is Rt. Sided SND

Lt +ve --> N/SND

 

2. Test	Rinne's	Weber's
   Rt	-ve
   Lt	+ve	lateralised
