Q

How might an acoustic neuroma present?

A
  • Gradual progressive unilateral deafness and tinnitus

Q

What is Rinne’s and Weber’s and what does a positive test indicate?

A

Weber’s - midline, tuning for 512Hx, normal hearing should be in the middle, if sounds louder in one ear then this indicates conductive hearing loss in that ear, or sensorineural hearing loss in other ear
Rinne’s - mastoid tip, should be louder in air next to ear, if not indicates conductive deafness

AIR CONDUCTION SHOULD BE BETTER THAN BONE CONDUCTION
