2. Presence of vertigo is associated with a less successful recovery
3. Age of patient (patients over 40 are less likely to recover)
4. Shape of audiograms (low & mid-frequency losses recover more frequently than
sloping or flat losses
Sudden Sensorineural Hearing Loss (SSHL) - Treatment - ANSWER-1) Steroids
(most common). Large doses over the first few days then dosage tapers off over the
next 2-3 weeks. Steroids are administered in 3 ways:
a. Oral
b. Intratympanic (injected directly into the middle-ear)
c. Combination of oral & intratympanic is most effective
2) Other treatments include diuretics, dietary, bed rest
Sudden Sensorineural Hearing Loss (SSHL) - Time course of recovery -
ANSWER-1. With medical treatment - occurs a few days to a few weeks
2. Without medical treatment - occurs within the first 2 weeks
,Note: After a couple of weeks there is very little chance of hearing recovery
What histological abnormalities have been reported in cases of Sudden
Sensorineural Hearing Loss (SSHL)? - ANSWER-Atrophy of the tectorial
membrane
What is Auditory Neuropathy? - ANSWER-A condition in which outer hair cell
integrity is normal but afferent auditory pathway is abnormal
Auditory Neuropathy Disorder - Efferent Pathway - ANSWER-Information is
coming from the brainstem & going to the IHC's. This is most of the nerve
innervation to the OHC's
T/F in Auditory Neuropathy Disorder, OHC's are fine; the problem exists at the
IHC level - ANSWER-True
Auditory Neuropathy Disorder - Site of lesion - ANSWER-IHC's. There is
synaptic dysfunction between the IHC's & the auditory nerve fibers resulting in
loss of myelin
Auditory Neuropathy Disorder - Etiology - ANSWER-1. Syndromic genetic
mutations - 40% of cases, 20% of which are idiopathic. Non-syndromic is not as
common
2. 40% of cases are acquired (prematurity due to underdeveloped IHC's,
hyperbilirubinemia due to underdeveloped liver)
Auditory Neuropathy Disorder - Management - ANSWER-1) Children & adults
are atypical patients. An audiogram does not tell the audiologist how well they are
able to understand speech & to communicate through the auditory pathway. Case
by case intervention must be approached comprehensively & systematically
, 2) Prosthetic Intervention
a. Amplification (half benefit & half do not)
b. FM system to improve signal to noise ratio
c. Cochlear implant
3. Communication training (listening strategies, speech reading training, manual
communication training such as sign language or cued speech)
Meniere's Disease - ANSWER-1. A disorder of the membranous labyrinth &
cochlear fluids

present in the following order:
1. Hearing loss (significant SNHL) 42%
2. Vertigo (serious) 11%
3. Tinnitus and/or aural fullness 3%
4. Hearing loss & vertigo 44%
Note: Meniere's Disease is often idiopathic unless syndromic
Meniere's Disease - Prevalence - ANSWER-1. Relatively rare (1% of adults)
2. Mixed evidence regarding gender
3. Rarely occurs in children
