Major Presentations
Hidden Hearing Loss
unaffected AC & BC but poor understanding of speech and noise
Antibiotics treat what
bacterial infections
A Schwannoma typically arises from the
Vestibular Nerve
Gold standard for diagnosis
MRI imaging
The Facial Nerve is 2/3 ____ and 1/3 ____
2/3 Motor and 1/3 sensory
Autoimmune Inner Ear Disease
weeks to months, progressive SNHL, no vertigo
Salicylates can cause
tinnitus, bilateral SNHL
Schwann cell growth is controlled by what gene
NF2
Neurologic symptoms of intracranial lesions can depend on
size, location, type, consistency
Paralysis vs Paresis
Paralysis is the loss or impairment over a body region as result of damage to the nerve supply
Paresis is slight or partial paralysis
Perilymph Fistula
sudden timeline (typically from previous head trauma), non-specific dizziness
For a patient with malaria, what medication would you give them?

Most common tumor of the
Temporal Bone
Multiple Sclerosis has a low incidence of auditory complaints because
Hearing deficits are not the most debilitating symptom
Bells Palsy is a diagnosis of
Exclusion
Meniere's Disease
Years timeline, initial episodic rotary vertigo 20 minutes or longer followed by prolonged disequilibrium and "tinny" hearing
causes a dose-related HL that generally recovers within 30 minutes to 56 hours
Loop Diuretics
Audiological test signs of VS
Asymmetric HF SNHL, poor out of proportion WR, positive rollover, elevated/absent ART to affected ear, abnormal ABR
Hallmark of retrocochelar dysfunction
Rollover
The two types of degenerative changes that follow axonal sectioning
Retrograde reaction and Wallerian degeneration
Superior Canal Dehiscence Syndrome
chronic disequilibrium, sound- or pressure-induced vertigo, BC hyperacusis, present reflexes, autophony
Most ototoxic Antineoplastic Agents
Cisplatin
NF1 vs NF2
NF1 has one VS
NF2 has bilateral VS
MS is more common in
Females, cold climates
