some questions you need to consider
Some questions you need to consider
  • How much time does it take?
  • Is this worth my time?
  • How much will it cost me? (time, money, emotions)
  • How do I get reimbursed?
  • My very first case
possible mechanisms
Possible Mechanisms
  • Abnormal rhythm or rate of spontaneous 8th nerve discharges
  • Increased spontaneous activity in dorsal cochlear nucleus resulting from reduced peripheral input
  • Unlike spontaneous activity, these neural discharges may become phasic and correlated
proposed mechanisms
Proposed Mechanisms
  • Imbalance of afferent and efferent:
    • Deficient afferent neurotransmitter glutamate at the cochlear-8th nerve synapse
    • “disinhibition” from neurotransmitters such as gamma aminobutyric acid (GABA)
  • Toxicity or imbalance of other of neurotransmitters
  • Ion channel regulation for excitability of neurons
  • Calcium induced changes in intra or extracellular processes (noise)
  • Vitamin B , zinc deficiencies?
proposed mechanisms5
Correlated activity across nerves by phase locking - ephaptic transmission

Extralemniscal neurons, particularly in dorsal cochlear nucleus and AII area, receiving input from somasthetic system

over-representation of edge-frequencies (neural plasticity)

Increased activity in one hemisphere (right OR left, but not both, as occurs during sound stimulation)

Enhanced perception hypothesis

Sensory remodeling in the central auditory system

Association with fear and threat (limbic system)

Proposed mechanisms
Models based on peripheral measures fail to predict completely percept laterality
    • Role of CNS adaptation (neural plasticity)
  • Absolute and relative depth of hearing loss are uncorrelated to percept severity
    • Role of CNS emotional binding (limbic system)

mechanisms etiologies
Mechanisms & Etiologies
  • Para-auditory structures (Tyler,1993)
    • Body continually produces noise that can be transmitted to the base of the skull.
    • Usually these noises are inaudible but the patient becomes aware of these noises for a variety of reasons
  • Vascular neoplasms, arteriovenous malformations, venous hum, TMJ syndrome, and muscle contraction tinnitus.
para auditory generation
Para-auditory generation
  • Vascular neoplasms
    • Cochlea detects blood flow
    • Potentially serious prognosis--symptom of vascular disease
    • Management--generally surgical
para auditory generation18
Para-auditory generation
  • Arteriovenous malformations
    • Developmental abnormalities--microscopic channels may canalize rapidly and result in rapid enlargement with increasing tinnitus
    • Often characterized by pulsatile tinnitus and may include distortion of the face or neck and discoloration of the skin.
    • Pulsatile rate increases with increased heart rate
para auditory generation19
Para-auditory Generation
  • Venous hum
    • Low pitched hum arising from the neck of many children and some adults, particularly young women.
    • Has been attributed to the transverse process of the second cervical vertebra impinging on the jugular vein.
    • Turning head away from involved side decreases it
para auditory generation20
Para-auditory generation
  • Venous Hum
    • Benign Intracranial Hypertension
      • Obesity
      • Menstrual irregularities
      • Hypothyroidism
      • Hyperthyroidism
      • Anemia
      • Vitamin A or D Deficiency
      • Side Effect of Oral Contraceptives
      • Pregnancy and Postpartum
para auditory generation21
Para-auditory Generation
  • TMJ syndrome
    • The petro-tympanic fissure is traversed by the mandibular ligament (Pinto’s ligament), the chorda tympani, and the anterior tympanic artery...disruption of these structures with a change or misalignment of the jaw can cause tinnitus and other ear symptoms
    • Diagnosis
    • Management
para auditory generation22
Para-auditory Generation
  • Muscle contraction tinnitus
    • Synchronous contraction of many or most of the fibers of one or more middle ear or palatal muscles (palatal myoclonus), either voluntary or involuntary
    • Pulsatile (clicking) tinnitus that does not change with changes in heart rate during exercise
    • Management (botox injections)
tinnitus unilateral
Tinnitus - unilateral
  • Coarse intermittent sounds coincident with jaw or head movements
    • Typical of a foreign body (i.e. cerumen, water or other liquids, or a hair resting against the tympanic membrane)
  • Fluttering
  • Stapedius muscle contractions
  • If associated with facial movements, then stapedial contractions are likely cause
  • Commonly seen after recovery from Bell’s palsy
  • When affected side of face contracts, ipsilateral stapedius muscle also contracts (synkinesis) due to aberrant facial nerve regeneration.
tinnitus unilateral or non lateralized
Tinnitus - unilateral or non-lateralized
  • Pulsatile
  • Clicking
  • Autophony (echoing of the voice), or blowing tinnitus
  • Hallucinations (non-verbal, stereotyped repetitive)
  • Determine whether it is related to cardiac cycle by comparing your silent count of patient’s cardiac pulse while patient is silently counting the pulsations of his/her tinnitus
pulsatile history
Pulsatile - history
  • An association with headaches, blurring of vision, and menstrual irregularities in an obese woman is suspicious for benign intracranial hypertension.
  • Abrupt onset with unilateral neck or head pains suggests a carotid dissection.
  • Changes in tinnitus intensity with head turning suggests a venous source for the tinnitus – from a source ipsilateral to the direction that decreases the tinnitus
  • If the patient can obliterate the tinnitus with localized pressure in the periauricular region then an emissary vein is probably accounting for the tinnitus.
  • An associated fluctuating hearing loss raises the possibility of microvascular compression of the auditory nerve causing the pulsatile tinnitus.

(Ohashi, Yasumura et al., 1992; Waldvogel, Mattle et al., 1998)

  • MRI studies of patients with unilateral tinnitus can detect vascular compression of the auditory nerve on the asymptomatic side as frequently as on the symptomatic side

(Makins, Nikolopoulos et al., 1998)

pulsatile physical exam
Pulsatile – physical exam
  • A crescent purple coloration to the tympanic membrane is diagnostic of a glomus jugulare tumor.
  • Otoscopic observation of a red mass behind the tympanic membrane is suggestive of an aberrant carotid artery, dehiscent jugular bulb, or vascular tumor.
  • A unilateral conductive hearing loss in association with ipsilateral pulsatile tinnitus and an otherwise normal exam may suggest otosclerosis, as does Schwartze’s sign (red hue behind the tympanic membrane on otoscopy).
  • Detection of a bruit ipsilateral to the pulsatile tinnitus suggests that the tinnitus is from the same source as the bruit. The source of the bruit then must be sought.
pulsatile physical exam31
Pulsatile – physical exam
  • Obliteration or reduction in the intensity of the pulsatile tinnitus with ipsilateral jugular compression (light or moderate pressure below the angle of the jaw) implicates a venous source of the tinnitus; whereas a decrease in the tinnitus with ipsilateral carotid compression implicates an arterial source arising from the carotid system.
pulsatile diagnostic studies
Pulsatile - Diagnostic studies
  • Because high cardiac output states such as anemia or hyperthyroidism can cause pulsatile tinnitus (usually bilateral), all patients should have a thyroid profile and a hematocrit.
  • If a carotid lesion is suspected then either a duplex ultrasound study of the carotid or MRA should be performed.
  • If a retrotympanic mass is suspected, then a high-resolution contrast-enhanced CT scan of the temporal bones should be obtained. Otherwise, a contrast-enhanced MRI scan of the temporal bone and cranium should be obtained.
  • If all non-invasive imaging studies have been unremarkable and raised intracranial pressure has been ruled out, then cerebral angiography should be considered, because a dural arteriovenous malformation can sometimes go undetected by another diagnostic study.
    • Because significant, but rare, morbidity can occur with angiography, careful deliberation must be given to the decision to proceed with angiography.
  • Relatively rare
  • Appears to be due to contractions of tensor tympani or the nasopharyngeal muscles controlling the patency of the Eustachian tube
  • It can sometimes be bilateral, in which case, it is usually associated with palatal myoclonus.
  • Often the clicking can be heard by the examiner
  • Sometimes acoustic impedance measurements have abnormalities that correspond
autophony echoing of the voice or blowing tinnitus
Autophony (echoing of the voice), or blowing tinnitus
  • Patulous ipsilateral Eustachian tube
  • Confirmatory features include disappearance of their complaints when their head is in a dependent position and abnormally large changes in the tympanic membrane acoustic impedance with respirations.
musical hallucinations
Musical hallucinations
  • Occur in elderly patients (more commonly in women) with a longstanding progressive moderate to severe bilateral hearing loss.
  • The tunes can be vocal and/or instrumental.
  • While usually bilateral, can be unilateral even with a bilateral hearing loss.
  • Can be precipitated by new medication, and resolved when medication is stopped.
auditory hallucinations
Auditory hallucinations
  • Differ from musical hallucinations in several respects
  • Usually abrupt in onset and associated with focal neurological findings due to a brainstem stroke or space occupying lesion
  • Brain imaging is required
tinnitus quality
Tinnitus quality
  • 85% of subjects reported having experienced another type of “normal” tinnitus; namely transient (typically less than a minute).
  • Transient tinnitus follows exposure to loud sound.
  • About 55% of population report such tinnitus lasting minutes to days.
always unilateral may be with vestibular symptoms
Always unilateral, may be with vestibular symptoms
  • Meniere’s Syndrome
  • Perilymphatic fistula
  • Herpes Zoster Oticus (Ramsay-Hunt Syndrome)
  • Cerebellopontine angle tumors
  • Central nervous system – caudal to trapezoid body
  • Sudden idiopathic hearing loss
meniere s syndrome
Meniere’s Syndrome
  • While the tinnitus is often described as roaring early in the illness, with more advanced stages of the syndrome, the tinnitus tends to become more variable in its description.
perilymphatic fistula
Perilymphatic fistula
  • Tends to be high frequency (hissing, crickets, etc.) with no recovery.
  • The defect can be caused by barotrauma, head trauma, valsalva, or erosion of the bony labyrinth due to an inflammatory or neoplastic process, or following middle ear surgery, such as stapedectomy.
  • Diagnosis can be suggested by the “fistula test” – the induction of nystagmus by positive or negative pressure applied to the external auditory canal.
herpes zoster oticus ramsay hunt syndrome
Herpes Zoster Oticus (Ramsay-Hunt Syndrome)
  • Intense ear pain followed by ipsilateral tinnitus, hearing loss, vertigo and facial paralysis
always with hearing loss may be unilateral or non lateralized
Always with hearing loss,may be unilateral or non-lateralized
  • Acute acoustic trauma
  • Chronic progressive hearing loss (presbycusis, chronic acoustic trauma, hereditary hearing loss)
  • Autoimmune inner ear disease
may be no hearing loss may be unilateral or non lateralized
May be no hearing loss, may be unilateral, or non-lateralized
  • Somatic (head or upper cervical)
  • Trauma
  • Post-infectious
  • Medication-related (including withdrawal syndromes)
somatic head or upper cervical
Somatic (head or upper cervical)
  • Higher incidence of tinnitus in normal hearing subjects with temporomandibular joint syndrome than in controls (Chole and Parker, 1992)
  • The same is true regarding whiplash (Tjell, Tenenbaum et al., 1999)
  • Tinnitus temporally associated with unilateral somatic disorders are localized to the ipsilateral ear (Levine, 1999a)
  • The physical examination should include:
    • Inspection of the teeth for evidence of bruxism, such as excessive wear of the bottom incisors
    • Palpation of the head and neck musculature for tender muscles under increased tension
    • Forceful systematic isometric concentration of muscle groups of the head and neck for their effects upon the patient’s tinnitus
properties suggesting somatic component
Properties suggesting somatic component
  • Intermittency
  • Large fluctuations in loudness
  • Variability of location
  • Diurnal pattern
  • No hearing loss but head or neck trauma
somatic diurnal fluctuations
Somatic – Diurnal fluctuations
  • Suggest somatic modulation is operative
  • Tinnitus louder upon awakening raises the possibility that somatic factors (such as bruxism) are active during sleep and are causing an increase in tinnitus loudness.
  • Tinnitus vanished by awakening and then returning a few hours into the day suggests that during the day they are re-activating their tinnitus through somatic mechanisms, such as the tonic muscle contractions required to support the head in an upright position or clenching related to the stress of daily activities.
  • Tinnitus that is louder after awakening from a nap in a chair may related to somatic factors such as stretching of the neck muscles when their head passively falls forward while dozing in a sitting position.
otoacoustic emissions
Otoacoustic emissions
  • While spontaneous emissions are common (75% of female and 45% of male normal or near normal ears), tinnitus due to spontaneous otoacoustic emissions is uncommon.
    • said to account for tinnitus of 1-2% of the patients of one British tinnitus clinic
  • The diagnosis is made by measuring an emission and showing that its suppression abolishes the tinnitus.
  • The emission can be suppressed in either of two ways:
    • Presentation of a low-level tone near the emission frequency
    • The use of aspirin (Penner and Coles, 1992)
soae associated tinnitus
SOAE-Associated Tinnitus
  • Accounts for 1-9 % of cases
  • May be hum or tonal
  • Generally in younger patients and localized in better ear
  • Responds to drug induced suppression
  • Case
sensorineural generation
Sensorineural Generation
  • Auditory deprivation and conductive hearing loss
  • SOAE-associated tinnitus
  • Cochlear disorders (SNHL)
  • Central processing effects
sensorineural hearing loss
Sensorineural Hearing Loss
  • 70-90% of tinnitus sufferers have hearing loss
  • NIHL is a major factor in approximately 38% of all tinnitus patients
  • Meniere’s is the next most prevalent etiology at 12%
  • The prevalence (not loudness) of the tinnitus is related to the severity of the hearing loss but it accompanies SNHL more frequently when the onset of the hearing loss is sudden
central processing effects
Central Processing Effects
  • The organization of the auditory system is dynamic--events causes changes within the system
    • Injury
    • Overstimulation
  • Moller (1995) and Cacace et al. (1995): Severe tinnitus & hyperacusis is caused by hyperactivity of the nuclei in the ascending auditory pathway, particularly within the inferior colliculus
auditory deprivation
Auditory Deprivation

Coles (1995) suggests that the central nervous system reacts to the lack of neural stimulation from the ear (phantom signal) by increasing its “attentiveness” to the auditory signals that do reach it, with consequent awareness of sounds arising from previously subliminal abnormal neural activity in the system.

effects of neurotransmitters
Effects of neurotransmitters
  • Acetylcholine - voluntary movement of the muscles
  • Norepinephrine - wakefulness or arousal
  • Dopamine - voluntary movement and motivation, "wanting", pleasure, associated with addiction and love
  • Serotonin - memory, emotions, wakefulness, sleep and temperature regulation
  • GABA - inhibition of motor neurons
  • Glycine - spinal reflexes and motor behaviour
  • Neuromodulators - sensory transmission - especially pain
Neurons expressing certain types of neurotransmitters sometimes form distinct systems, where activation of the system causes effects in large volumes of the brain, called volume transmission.
  • The major neurotransmitter systems are the noradrenaline (norepinephrine) system, the dopamine system, the serotonin system and the cholinergic system.
  • Drugs targeting the neurotransmitter of such systems affects the whole system, and explains the mode of action of many drugs;
    • Cocaine, for example, blocks the reuptake of dopamine, leaving these neurotransmitters in the synaptic gap longer.
    • Prozac is a selective serotonin reuptake inhibitor (SSRI), hence potentiating the effect of naturally released serotonin.
    • AMPT prevents the conversion of tyrosine to L-DOPA, the precursor to dopamine;
    • reserpine prevents dopamine storage within vesicles;
    • deprenyl inhibits monoamine oxidase (MAO)-B and thus increases dopamine levels.
  • Aspirin, ibuprofen, advil NSAIDs, naproxen, motrin
  • Dristan, anacin, excedrin, bufferin
  • Alka seltzer, pepto bisomol, pamprin, certain breath savers, lozenges, wintergreen

tinnitus and hearing loss79
Tinnitus and hearing loss
  • Only 5% of the patients had normal hearing at all frequencies. Twenty-two percent were suitable as hearing aid candidates, but only half of these actually used them. Thus, the remaining 73% possessed a hearing loss, but this was too localized for the high frequencies for hearing aids to be beneficial.
          • (Davis, Wilde & Steed, 1999)



The mean hearing threshold levels of ninety consecutive patients in a university tinnitus clinic are displayed in Figure 1 (Davis, Wilde & Steed, 1999)

common cognitive distortions
Common cognitive distortions
  • All or nothing thinking = no shades of gray; my life used to be perfect, now it is horrible
  • Mental filter = one aspect of a complex situation is the focus of attention, while others are ignored; I was having a good time at the party, but my tinnitus ruined everything
  • Mind reading = assuming other’s thoughts without evidence, people think I’m dumb when I ask them to repeat
  • Jumping to conclusions = assuming negative expectations about future events as established facts I will have a lousy day when my tinnitus is the first thing I hear in the morning
  • Emotional reasoning = assuming emotional reactions reflect the true situation; my tinnitus makes me feel hopeless, there is no hope
  • Labeling = attaching a global label to oneself rather than to specific events or actions; having tinnitus makes me a disabled person



Common cognitive distortions

  • Overgeneralization = an event is characteristic of life in general, as opposed to specific; because of my tinnitus I was awake sall night. Every night is the same.
  • Disqualifying the positive = positive experiences that would conflict with negative views are discounted; I did better today, but that was a fluke
  • Catastrophizing = negative events are treated as intolerable rather than in perspective; my tinnitus is louder, I must be going deaf
  • Should statements = using should and have to statements to provide motivation or control; I should never have listened to rock music
  • Personalization = assuming one is the cause of a particular event when in fact other factors are responsible; I ruined everyone’s evening because I was miserable

differences between cbt and trt
Differences between CBT and TRT
  • Cog therapy is intensive, collaborative with 8-12 weekly sessions and testing of hypotheses;
  • TRT directive counseling is directive with 4-6 sessions over 18 months.
  • Tinnitus remains, but coping skills improve

turf wars
Turf Wars
  • Psychologists say… TRT is nothing new
    • Jakes and Hallam basically described it years before it became popular
    • TRT suffers from lack of methodological confirmation (i.e. no treatment waiting control groups)
    • Does not consider depression and anxiety
    • As many as 40% of tinnitus patients may suffer from depression and anxiety
    • Consider interaction/collaboration more important than directive counseling
    • TRT does not teach coping strategies
    • CBT takes 8-12 weeks, not 18 – 24 months

sound therapies
Sound Therapies
  • Masking
  • Partial Masking
  • Mixing
  • Ultrasonic therapy (hi sonic, quiet sonic) - unproven
  • Music
  • DTM sounds use proprietary “dynamic” (changing) sound formats that are intended to enhance masking and distract attention away from tinnitus.
  • “Dynamic” acoustic technology refers to proprietary semi-random, short-term amplitude and frequency domain modulation signal processing
  • E-Nature and E-Water, have been “dynamically” processed to provide expanded amplitude peaks on the order of 5 to 15 dB, over corresponding time durations on the order of 10 to 500 msec.
ultrasonic sound generators
Ultrasonic sound generators
  • Ultra Quiet (6-20KHz BC)
  • Hi-Sonic TRD (19-27KHz BC)
  • Melmedtronics Inhibitor
    • 60 sec ultrasonic signal with hand held bone vibrator to mastoid (19-25KHz or 42-48 KHz). Claims it works on 75% of patients (by being out of phase of tinnitus!!!!)
    • non-returnable
sound enhancement for desensitization habituation
Sound enhancement for desensitization / habituation
  • low level noise interferes with pattern recognition by increasing neuronal activity
  • this makes tinnitus more difficult to detect / reduces contrast
  • gradually increasing input could decrease gain over an extended time
acceptable noise level
Acceptable noise level
  • Nabalek’s ANL measures patient’s willingness to accept background noise when listening to speech

MeanTinnitus Awareness (Percentage of the Time) at Follow-up. Means are the percentage of time which participants were generally aware of their tinnitus over the preceding week.

  • Noise = 41.9%
  • Counseling = 39.2%
  • Music masking = 30.4%
  • ADP = 12.3%

Davis et al, 2002

why can t we just use an ipod
Why can’t we just use an iPod?
  • Frequency shaping
  • Loudness balance
  • Compression
music can be soothing or irritating
Music can be soothing or irritating
  • The physical body and chakra centers respond specifically to certain tones and frequencies.
  • Meditation and Relaxation recordings may actually produce adverse EEG patterns, as much as Hard Rock and Heavy Metal.
    • With “perceived” soothing sounds, a right/left brain hemisphere synchronization occurs; voltage spike pattern smoothes and voltage differential equalized.
  • Selecting what will work for any individual is difficult.
  • We all have different tastes
categorical expectations
Categorical Expectations
  • We don’t like the unexpected
  • But certain rules have to be followed
  • Active listening arouses, passive listening soothes
  • Active listening distracts, passive listening may allow for increased cognitive function
  • For tinnitus patients, active listening draws attention to the tinnitus, passive listening may facilitate habituation
selecting the right sound
Sounds affect people in different ways, due to inherent and learned preferences (Iversen et al, 2000).

It is thus important to use relaxing background sounds (that activate the parasympathetic division of the autonomic nervous system) and avoid exposure to negative or annoying sounds (that activate the sympathetic division)

Bolero example

Selecting the right sound
does sound therapy help
Does sound therapy help?
  • McKinney, et al; 1999
    • Counseling only; 72% showed “improvement” (N=54)
    • Counseling with sound generators at just audible level; 75% showed “improvement” (N=72)
    • Counseling with hearing aids; 61% showed “improvement” (N=56)
    • Counseling with sound generators at mixing level; 83% showed “improvement” (N = only 36)
does sound therapy help140
Does sound therapy help?
  • Herraiz, et al, 1999
    • Counseling only; 94% showed “improvement” (N ~ 30)
    • Counseling with hearing aids; 85% showed “improvement” (N ~ 35)
    • Counseling with sound generators; 83% showed “improvement” (N ~ 30)

My conclusion….not definitive proof….yet 70% of TRT users get them!

  • Reduction in the number of episodes of awareness
  • Increase in the intervals between episodes of awareness
  • Increase in quality of life
  • Not necessarily a reduction in perceived loudness
psychological treatment objective
Psychological Treatment Objective
  • Tinnitus remains, but coping skills improve
  • “I have tinnitus, it doesn’t have me.”
so what works
So what works?

Any of the “reasonable” approaches, depending on the “skills” of the audiologist

some suggestions
Some suggestions….
  • Ask “what will make this encounter or therapy successful in your mind?”
  • Remember that tinnitus patient management is a journey, remind patients of the ups and downs to be expected
  • Tell patient that 1st thought upon recognizing tinnitus should be…..
counsel about the following
Counsel about the following:
  • Tinnitus is not unique to that one patient.
  • Tinnitus is not a sign of insanity or grave illness.
  • Tinnitus may be a “normal” consequence of hearing loss
  • Tinnitus probably is not a sign of impending deafness.
  • There is no evidence to suggest the tinnitus will get worse.
  • Tinnitus does not have to result in a lack of control.
  • Patients who can sleep can best manage their tinnitus.
counsel about the following146
Counsel about the following:
  • Tinnitus is real, and not imagined.
  • Tinnitus may be permanent.
  • Reaction to the tinnitus is the source of the problem.
  • Reaction to the symptom is manageable and subject to modification.
  • If significance and threat is removed, habituation or "gating" of attention can be achieved.
  • Stay off the internet!
