HEARING LOSS
PromptTuning fork hearing tests - Describe
ResponseWeber (fork in middle of head)
Normal = same both sides. Conductive loss = louder in bad ear, sensorineural lateralises to good ear
Rinne (fork on mastoid then outside EOM)
Normal/sensorineural - Air conduction lasts longer than bone conduction
Conductive loss = bone condution longer than air

Rinne (fork on mastoid then outside EOM)
Normal/sensorineural - Air conduction lasts longer than bone conduction
Conductive loss = bone condution longer than air
PromptCauses of atraumatic sensorineural hearing loss
ResponseIdiopathic (majority)
Meds - Aspirin, aminoglycosides
Vascualr - Vasculitis, small vessel disease of 8th n. Eg: Diabetics
Inflammatory eg: sarcoid
