Acoustic Neuroma – HEARING TEST 2
The key terms of hearing test 2 include, Acoustic Neuroma, Tumor, Non-organic hearing loss, sensor neural hearing loss, Pseudohypacusis, Vertigo, Meniere’s disease, Auditory neuropathy, hearing test
Acoustic neuroma
Tumor on the acoustic nerve
grows slowly and can be treated if caught early
Indicators of acoustic neuroma
Unilateral high frequency sensor neural hearing loss
poorer than expected word
absent or elevated acoustic reflexes
acoustic reflex decay
Non-organic hearing loss
Pseudohypacusis
functional
nonorganic
psychogenic
malingering
Pseudohypacusis
Fake hearing loss
Vertigo
Sensation of spinning/falling in absence of direct external stimulation
– Always
Meniere’s disease symptoms
Sudden attacks of vertigo, nausea, tinnitus, fullness and unilateral hearing loss
Rapid growth of perceived loudness in a pitch region containing hearing impairment
Auditory neuropathy has what kind of OAE and ABR
Normal OAE
abnormal ABR
Hearing loss of meniere’s disease
Fluctuating and progressive with very poor WRS
Balance system major function purposes
Know where you are in space
maintain clear visual image during movement of head
maintain upright stance
Two sections of inner ear
Choclea
vestibular system
Functional
Loss with no organic disorder detected
Nonorganic
Apparent loss with no known disorder or insufficient evidence to explain it
