Final Exam Flashcards
1
Q
what is tinnitus
A
Tinnitus is the perception of sound occurring in the ear or head when no external sound is present
Phantom auditory perception
It is a symptom, not a disease/disorder
2
Q
what are the theories of peripheral mechanisms
A
cellular mechanisms
edge theory
discordant damage of IHC & OHC
tectorial membrane displacement
NTs & receptors
Synaptopathy
3
Q
what are the theories of central mechanisms
A
auditory deprivation
inhibitory gating mechanism
hyperactivity & hypersynchrony
neural crosstalk
MOC dysfunction
4
Q
complex sensory network that allows our brain to perceive and interpret sensations from the body
A
Somatosensory mechanisms
5
Q
triggers for tinnitus of Somatosensory mechanisms
A
temporomandibular joint syndrome or whiplash
Anything related to the head and neck
6
Q
what is the limbic system
A
Involved in our behavioral and emotional responses - feeding, reproduction, caring for our young, and fight or flight responses
7
Q
what is the limbic systems role in tinnitus perception
A
Mediates the emotional response to tinnitus
Those with strong emotional responses often show enhanced sympathetic nervous system activity - fight or flight response
When it is heard there is a reaction and the reaction is controlled by this system and it can make it worse which explains why some cannot ignore it while others can
8
Q
what can make the tinnitus worse in regards to the limbic system
A
Anatomical or physiological abnormalities in the limbic system - lead to emotional reactions to the tinnitus
if there is any lesion or damage, limbic system will not block the tinnitus signal meaning that all of it reaches the cortex and perceived causing it to be loud and clear
9
Q
Greater brain connectivity between auditory and limbic areas =
A
more distress levels
10
Q
subjective tinnitus
A
most common
heard only by the PT
can be bothersome or nonbothersome
11
Q
common causes of subjective tinnitus
A
Ototoxicity - high-pitched sound
Meniere’s - LF tinnitus with vertigo & HL that fluctuates
OTSC - high-pitched, white noise and can initially be pulsatile
12
Q
ototoxicity tinnitus
A
high pitched
13
Q
meniere’s tinnitus
A
LF tinnitus with vertigo & HL that fluctuates
14
Q
OTSC tinnitus
A
high-pitched
often white noise
can initially begin as pulsatile
15
Q
how does OTSC cause tinnitus
A
CHL causing deafferentation (reduced auditory information going to the brain)
Reduction of masking effect - ex if you cover your ears you miss hearing the environmental noise
Environmental noise can mask the tinnitus but if you have CHL this is not the case so you hear it more
Rich blood supply causing pulsatile
Arteriovenous malformations
Cochlear tinnitus caused by toxic enzymes produced by otosclerotic bone, bony invasion of the cochlea, and damage to the cochlear blood supply
16
Q
What is the common description of tinnitus reported by patients with otosclerosis?
A
Usually the first symptom noted is pulsatile in nature.
17
Q
Tinnitus is a common symptom in otosclerosis patients and sometimes it can appear as the first symptom, explain.
A
If tinnitus is the initial symptom, it suggests that the patient hasn’t yet experienced conductive hearing loss. This means there’s no auditory deprivation triggering the brain to compensate for the reduced auditory input.
18
Q
objective tinnitus
A
heard by the PT and examiner; sounds generated within the body and can be audible to another person
Rare
Vascular or mechanical in origin - Usually due to vascular disturbances or muscular spasms in the head/neck
19
Q
causes of objective tinnitus
A
Glomus tumors
ME muscle spasms
Palatal myoclonus
ETD
20
Q
acute vs chronic tinnitus
A
acute - short duration, <6 mos, associated w/ recent exposure triggers, high chance of spontaneous recovery
chronic - persistent, >6mos, involved in sustained neurobiological changes, less chance of spontaneous recovery
21
Q
bothersome vs nonbothersome tinnitus
A
bothersome - significantly impacts quality of life
nonbothersome - has minimal impact
22
Q
primary tinnitus
A
Tinnitus that is idiopathic & may or may not be associated with SNHL (source is unknown)
If we do not know the cause or disorder that caused it
23
Q
secondary tinnitus
A
Tinnitus that is associated with a specific underlying cause (other than SNHL) or an identifiable organic condition
If we do know the cause of the tinnitus
24
Q
auditory and non-auditory cauess of secondary tinnitus
A
Auditory causes: impacted cerumen, ME diseases, cochlear abnormalities, auditory nerve pathology
Non-auditory causes: vascular anomalies, myoclonus, intracranial hypertension, tonic tensor tympani syndrome, TMJ disorder
25
pulsatile tinnitus
characterized by the sound that is rhythmic and resembles the heartbeat
26
somatosensory tinnitus
Tinnitus caused or influenced by sensory input in the body
apply pressure or clench jaw etc. and they notice the tinnitus
27
Somatic and pulsatile could be classified as secondary because we know what is causing it
true
28
what are ways to classify tinnitus
temporal characteristics, duration, impact
29
what are temporal characteristics
how often they experience the tinnitus
broken down into spontaneous, temporary, occasional, intermittent & constant
30
spontaneous
sudden sound, usually unilateral lasting 2-3 min
31
temporary
lasts minutes to days often after noise exposure or medications and can accompany TTS
32
occasional
occurs less than weekly (e.g., every few weeks, months or every few months) and lasts at least 5 minutes
33
intermittent
occurring regularly (daily or weekly) and lasts at least 5 minutes
34
constant
continuous sound
35
what is duration
how long you had it
classified:
recent/acute: experienced less than 6 months
persistent/chronic: experienced for >/= 6 months
36
impact
how does it affect their life or interfere
classified: bothersome or nonbothersome
37
pulsatile tinnitus
In synch with the heartbeat
Rhythmical noise usually the same beat as the heart
Usually caused by blood flow changes near the ear or by a change in awareness of blood flow
whooshing sound
38
causes of pulsatile tinnitus
Hypertension
Hyperthyroidism
Vascular stenosis
Unilateral head or neck pain with abrupt tinnitus onset = carotid dissection
Tinnitus intensity changes with head movement = venous source
39
how to determine if it is pulsatile tinnitus
Complete audio testing - comprehensive audio, tymps, reflexes
DPOAEs
Find pulse to determine if pulsing matches tinnitus
Tinnitus of venous origin can be suppressed by compressing the jugular vein
Use 2 fingers to press firmly on SCM muscle & carotid artery for 10 sec. On the right and left sides of the neck
Ask PT if pulsing changes in any way (may stay, go away or change to a different sound)
If it does change, refer for medical workout of vascular pathways
40
glomus jugulare symptoms
HL is the main presentation - unilateral CHL or mixed
Pulsatile tinnitus (decreases when you push on carotid), vertigo, otorrhea, CN involvement
Red ™ - rising sun appearance
41
what is clicking tinnitus
Rare
Can be objective; somatosounds
Not all are detectable by examiner
appears to be due to contractions of the tensor tympani or the nasopharyngeal muscles controlling the patency of the ET
Or a symptom of ME myoclonus (jerking of a muscle group)
Bilateral clicking = palatal myoclonus
42
bilateral clicking
palatal myoclonus
43
clinical manifestations of clicking tinnitus
May be seen on tymps
Detectable using ARTs or decay
Reflexes sometimes are too short
Have PT tap their leg when they hear it and look for corresponding results to the taps
44
how to find clicking tinnitus
Have PT tap their leg when they hear it and look for corresponding results to the taps on reflex decay
45
should you refer for clicking or pulsatile tinnitus
yes
46
clinical manifestations of somatosensory tinnitus
Normal hearing
Symptoms - High-pitched constant ringing
No other hearing or vestibular complaints & neurological exams show no abnormalities
47
how to determine if it is SS tinnitus

Temporomandibular joint
Have PT clench their jaw for 10 s. Any change in tinnitus?
Have PT open jaw wide/protrude jaw for at least 5s. Any change in tinnitus?
Maneuvers involving the neck
Active neck movements - with and without resistance
Passive muscular palpation in order to search for myofascial trigger points (MTP) or tender points

Patient request for ENT/audiological assessment
Tinnitus in association with significant neurological symptoms
50
An 87-year-old woman had a year of intermittent severe hissing tinnitus that could be left ear only or bilateral. It followed a cyclical pattern. Following a day or two of no tinnitus, it would begin softly in the left ear but over the next two days become progressively louder as it spread to both ears. It would then lessen over the next two days or so, until the tinnitus was heard only in the left ear and ultimately would disappear completely. She had a long history of bruxism and muscle contraction headaches (tightness over her temples and jaw). When her tinnitus was severe her headaches were severe.
Her audiogram showed symmetric mild sloping to moderately severe SNHL, bilaterally.
At a visit when her tinnitus was extremely loud (10/10) and bilateral, somatic testing was performed.
Her tinnitus loudness decreased to 4/10 and became unilateral (left ear only).
These changes in her tinnitus persisted for the remainder of that visit (20 minutes).
By the next day, her tinnitus had disappeared completely, but the usual cycle then returned within a day or two.
Type: somatosensory (changes intensity when things change - she has jaw problems, clenching causes migraine,s and comes and goes with certain things)
Maneuver relaxed the muscle which is why it could’ve decreased the intensity
51
A 33-year-old man was seen because of non-lateralized tinnitus. His mother had been diagnosed with terminal lung cancer about three weeks earlier, and he had been closely involved with her care. Two days before her death as he was trying to sleep, his tinnitus began. It was described as a high-pitched ringing similar in pitch but much louder than the transient tinnitus he had previously experienced following loud sound exposure. Clenching or turning his head would aggravate his tinnitus. His exam and audiogram were normal. Despite four years of a variety of treatments, his tinnitus has persisted, and he remains distressed. what is the tinnitus & what referrals should be made if any
Type: dishabituation because he experienced tinnitus before and it was gone (occurred due to some change, he habituates and then he is fine and it comes back and the brain perceives it as a new stimulus)
Value of digging into the history of PT
He has normal hearing
Mental health services to deal with the stress and this might change the vicious cycle
52
Most common sound a patient will report for tinnitus is
ringing
53
pushing/whoosing
pulsatile
54
Count the beats you feel and at the same time ask the PT to count the number of tinnitus beats they hear
technique for pulsatile tinnitus
55
Confirmed with tone decay because it provides a larger time window whereas a reflex is shorter (can se there too) and gives a better chance to see it
Every time you hear the clicking sound tap your foot and watch decay and changes confirm the clicking
clicking tinnitus
56
Related to muscle spasms, etc.
Do maneuvers to confirm this
Changes tinnitus (can be worse, different tone, different volume, etc.)
Change the head and jaw and have the PT tell whether there is a change in tinnitus
They can protrude the jaw or clench the teeth and ask if there is a change
Can do head movements
somatosensory tinnitus
57
Objectives of psychoacoustic assessments
Rule out or confirm disease or pathology underlying tinnitus
Document health conditions and factors influencing tinnitus perception
Evaluate auditory function to identify peripheral or central auditory dysfunction associated with mechanisms of tinnitus
Describe and quantify the severity of PT tinnitus
Define impact of tinnitus on quality of life
Contribute to decisions regarding an effective management plan
58
what is pitch masking and the goal
Estimate the general frequency region of the patient’s perceived tinnitus
Goal: to determine the frequency of a tone or noise that is closest to that of the PT’s most bothersome tinnitus
59
what should the presentation be for pitch masking
stimuli at 10 – 20 dB SL at frequencies with normal limits
Stimuli at 5 –10 dB SL at frequencies with hearing loss.
60
where do you present for pitch masking
Start by presenting 1000 & 2000 Hz tone to the “stimulus ear” (contra ear to the ear with tinnitus)
Unilateral tinnitus: present stimulus to the non-tinnitus ear (stimulus ear)
Bilateral tinnitus: present stimulus to the ear with the softest tinnitus. If tinnitus is perceived the same in both ears, test either ear or the ear with the better thresholds.
61
what is octave confusion
where a person incorrectly identifies the pitch of their tinnitus by choosing a frequency that is either one octave above or below the actual tinnitus pitch.
62
what is loudness matching & the goal
Obtain loudness match at the pitch-matched frequency
Goal: to determine the loudness of a tone or noise that is closest to that of the PT’s most bothersome tinnitus
63
where should you start for presentation for loudness matching
Start 5 dB below the AC threshold and then gradually increase the level in 1-dB steps until the patient hears the tone.
64
what is tinnitus quality match
Tinnitus Matching to Bands of Noise
Determine whether tinnitus sounds like a tone or like noise
65
what is MML
minimum masking level
66
what is MML & the goal
Identify the lowest level of BBN that completely masks the tinnitus
Goal: Determine the lowest level of BBN that completely masks the tinnitus (MML).
Determine whether patient’s tinnitus is bilateral or unilateral.
67
how to present MML
The masking noise should be presented binaurally for patients with bilateral tinnitus, and monaurally for patients with unilateral tinnitus.
68
what is RI
residual inhibition
69
what is the goal of RI
To characterize the patient’s tinnitus as a supplement to MML testing and to demonstrate that BBN can have a positive effect.
70
Negative RI
no change in tinnitus perception
71
Positive - Complete RI
complete absence of tinnitus perception in both ears (0% of the usual tinnitus loudness)
72
Positive - Partial RI
If there is a perceptible reduction in tinnitus loudness in one or both ears.
Ask the patient to estimate the current loudness as a percentage of their usual loudness (10%, 25%, 50%, 75%, or 90%).
73
Rebound or Exacerbation
If there is an increase in the tinnitus loudness level
74
Initial intake appointments are for most PTs to give brief education counseling & HA’s if needed what does this include

Describes and quantifies the severity of the PT’s tinnitus
Contributes to decisions regarding an effective management plan
106
Unilateral tinnitus
Secondary tinnitus (somatosounds)
Pulsatile tinnitus
Whether it is in beat or not with the heartbeat
Mental health professionals when warranted
refer
107
when should you refer to ENT
Vestibular symptoms (vertigo/dizziness)
Otalgia & otorrhea
Tinnitus of somatic origin (pulsing w/ heart)
108
when should you refer for ENT or emergency care
Tinnitus plus any of the following
Physical trauma - facial palsy
Sudden idiopathic HL
109
when should you refer for mental health or emergency care
Tinnitus plus any of the following
Suicidal ideation
Obvious mental health concerns
110
should you refer for SNHL & tinnitus findings
advised you do
further diagnostic testing is not needed but otology should rule out physical causes of tinnitus
111
Tinnitus of sensorineural origin
Hx of noise exposure w/ concurrent or subsequent onset of tinnitus
Symmetrical, stable, and non-pulsatile tinnitus
Long duration tinnitus
Audio consistent w/ symmetrical SNHL
should refer
112
decrease HL sensitivity, no red flags (it is symmetrical), suggests SNHL, what is the recommendation?
HAs
Needs medical clearance
113
what can otoscopy reveal
can check for pulsatile tinnitus, might see tumors, cerumen impaction (can cause tinnitus)
114
how can you verify thresholds with pure tones
present one after another to confirm, after establishing all of the thresholds for AC go down 5dB and present and there shouldn’t be a response but when you go back to the threshold there will be a response (threshold is 35 dB go to 30 and present and no response then go back to 35 and there should be a response
115
why is SRT done
to cross check PTA & make sure pure otnes are reliable
116
why include HF audiometry
Especially for those with hearing
Shows HF HL before pure tones will
Early indication there is damage in the IE
117
why do we include LDL
Decides whether they have hyperacusis
Helps with HA’s to make sure we don’t exceed this level
118
why is WRS included
Used for HA assessment
Shows if there is retro pathology (unilateral tinnitus, HL & poor wrs)
119
why are OAEs included
Confirm cochlear origin by identifying absent or below-normal amplitudes in PTs with SNHL
correlatioin between perceived tinnitus and the low or abs amplitudes in OAEs
Identify cochlear dysfunction in PTs with normal hearing sensitivity, providing a physiological explanation for their tinnitus symptoms
if they have unilateral tinnitus this can show abnormal OAEs with normal OAEs in the other ear
Validates auditory basis, especially with normal audios
120
why are tymps included
rules out conductive component
121
why include ARTsx
Helps to rule out conductive components or if there is a lesion in the reflex arc (tumors)
If PT is sensitive here, you can try using BBN to give an idea of a reflex
122
why do we include reflex decay
Would want to include if retro cochlear pathology is suspected (acoustic neuroma, vestibular schwannoma, other lesions in CANS)
Would also want to include if clicking tinnitus is suspected
123
why would yo include quick-sin
If suspecting HHL
Individual has normal hearing sensitivity but they share issues with hearing speech in background noise
Shows SNR loss
124
vernon's 2dB rule
Loudness match - repeat 5-6x with other tests intertwined between the repeated tests
Each loudness match is obtained to the nearest 1dB
Presence of tinnitus is indicated if the repeated results within a session agree to be within 2 dB
Different trial runs have to be witin 2dB of each other
Recent studies challenge validity of 2dB rule demonstrating that test-retest reliability is similar for individuals with and without tinnitus
125
what is the goal in those with legal claims
establish if the responses are consistent, plausible, & credible across all assessment components
126
Legally, assessments focus on
reliability of psycnoacoustic measures , the consistencies of responses, & tinnitus duration determine its permanency
127
what must you keep in mind with those loking for legal claims
Must stay alert to exaggerations in self-reports, aiming to confirm consistency, plausibility and credibility of responses
128

130
Case 3
Case history
Referral: referred by his primary care physician.
The patient was employed in a post office where his duties included unloading and sorting mail. History was remarkable for chronic exposure to recreational noise (loud engines and sports events).
Perceptual Features: Bilateral, high-pitched ringing tinnitus. Tinnitus is noticed three weeks earlier after waking up one morning.
Patient had a history of bruxism. He reported trying two different over-the-counter mouth guards to minimize the condition. Despite wearing these mouth guards, the patient’s tinnitus became more noticeable. It was unclear if his bruxism intensified or the over-the-counter mouth guards caused the tinnitus to become more noticeable.
He reported an increase in anxiety in the past month with several panic attacks, for which he took Alprazolam, that was prescribed to him by another clinician on several occasions.
Management history: None
Tinnitus impact questionnaire
Severe
Audio results
Normal otoscopy, mild HF SNHL, mild ultra HF loss
What factors in Chris’s history might be related to the etiology of her tinnitus?
What factors in Chris’s history might be exacerbating her tinnitus?
Does Chris require additional tinnitus intervention?
What referrals may be appropriate for Chris?
noise exposure, history of TMJ, and stress (possibly the medication could have made it worse but he had the tinnitus before the medication)
stress, jaw, possibly the medication
yes
referral to TMJ specialist because it is affecting his neck and everything and could be increasing his tinnitus
131
what are fxnal effects of tinnitus
Sleep disturbances, difficulties concentrating and varying emotional impacts
There is no solution to fit everyone because the causes are all different from patient to patient and we do not know the exact mechanism that causes the tinnitus
132
Multidisciplinary collab/referrals
Do the assessment to help them and as you identify certain issues you want to refer them to specialties to help manage what could be the cause
Otolaryngology
Psychology
Cardiologist
TMJ specialist
Massage therapist: Get a massage to relieve stress and tension
Neurologist
Sleep specialist - for those that are unable to fall asleep
133
what are managment options
HAs
Sound therapy
Masking devices
Music therapy
Sound apps
Lifestyle modifications
Education & counseling
TRT
CBT
Mindfulness
Physiotherapy
Transcranial magnetic stimulation
Bimodal neuromodulation
Drug therapies
Supplements
Low-level laser therapy (LLLT) - a light therapy that has been used to treat tinnitus, with some studies showing positive results
134
If they have bothersome tinnitus with mild HL would you recommend HA’s?
yes
135
how do HA's help
Improves hearing-related quality of life
Reduces attention to innitus
Reduces stress & fatigue related to straining to hear
Stimulates the auditory system
Might prevent maladaptive neuroplastic changes in the auditory system
136
what do HA work best with for tinnitus
LF hearing is good
Tinnitus pitch below 8kHz (within HA fitting range)
Strong reactions to tinnitus
137
which Rx method is best for tinnitus
DSL has more gain for the LFs
Most of the ambient noise is LF so this helps to cover the tinnitus by giving the PT access to the LF soft sounds (ambient sound)
138
what features are good for HA's
Bilateral HL = bilateral amp
Open dome = less LF occlusion - allows more natural sound in to mask the tinnitus
Low compression TK = more audibility of soft sounds (adds more gain to low intesnsity sounds)
Turn off expansion = expansion reduces amplification of soft sounds to prevent them from distracting the wearer
But in tinnitus we want this
Omnidirectional mics = allows sounds from different directions to allow stimulation and ignore the tinnitus
Noise reduction off
Sound therapy program
BT connection to access therapy sounds
Frequency lowering - depends
139
what is sound therapy
Uses sound to decrease the loudness or annoyance of tinnitus
140
what are types of sound therapies used
music
noise - white, pink, brown, BB, NB
Relaxation or environmental sounds
Waves, rain, breezes, etc.
141
Lit Candle in a Dark Room Analogy
In a dark space the candle is bright because the room is so dark and you focus more on the light
if you hear nothing and then there is tinnitus then they are paying more attention to it – gets louder in quiet – because they pay attention to it more in the presence of nothing
If you take that same candle and turn the lights on or put it in a lit room the candle is still there but it is less noticeable because you can focus on other things
if there are external sounds, the tinnitus is still there but you are not paing attention to it as much as before because there are other sounds that keep the PT busy
