Definition
TINNITUS: the conscious awareness of
sound, perceived in the ear/ears or
head, lacking an external, driving sound
source or mechanical activation of the
cochlea.
Objective Tinnitus
• Objective tinnitus – sound produced by causal
pathology which may be heard by an examiner
(usually via amplified stethoscope)
• Pulsatile tinnitus – matches pulse
• Possible vascular etiology
– Either objective or subjective
– Increased or turbulent blood flow through
paraauditory structures
Objective -Pulsatile tinnitus
• Arteriovenous
malformations
• Vascular tumors
• Venous hum
• Cardiac murmurs
• Pregnancy
• Paget’s disease
(disorganized bone
remodeling)
• Benign intracranial
hypertension
Arteriovenous malformations
• Pulsatile tinnitus
• Headache
• Papilledema (Optic Nerve Swelling-a hallmark
of elevated intracranial pressure)
• Discoloration of skin or mucosa
Venous hum-associated causes
•
•
•
•
Benign intracranial hypertension
Dehiscent jugular bulb
Transverse sinus, partial obstruction
Increased cardiac output from:
– Pregnancy
– Thyrotoxicosis
– Anemia
Benign Intracranial Hypertension
(BIH)-presentation

Young, obese, patients
Hearing loss
Aural fullness
Dizziness
Headaches
Visual disturbance
Papilledema
Muscular Causes of Tinnitus
• Palatal myoclonus
– Clicking sound
– Rapid (60-200 beats/min), intermittent
– Contracture of tensor palantini, levator palatini,
levator veli palatini, tensor tympani,
salpingopharyngeal, superior constrictors
– Muscle spasm seen orally or transnasally
– Rhythmic compliance change on tympanogram
Myoclonus-associated causes
• Palatal myoclonus associations:
– Multiple Sclerosis and other degenerative
neurological disorders
– Small vessel disease
– Tumors
• treatments: muscle relaxants, botulinum toxin
injection
Stapedius Muscle Spasm
• Idiopathic stapedial muscle spasm
–
–
–
–
–
Rough, rumbling, crackling sound
Exacerbated by external sounds
Brief and intermittent
May be able to see tympanic membrane movement
Treatments: avoidance of stimulants, muscle
relaxants, sometimes surgical division of tensor
tympani and stapedius muscles
Patulous Eustachian Tube
•
•
•
•
Eustachian tube remains open abnormally
Ocean roar sound
Changes with respiration
Lying down or head in dependent/particular position
provides relief
• Significant weight loss, radiation to the nasopharynx
• Can sometimes change tympanometric compliance
readings with respiration
Subjective Tinnitus
• Much more common than
objective
• Usually non-pulsatile
• Heard only via the patient
• No consensus regarding
exact mechanism(s) of
tinnitus production
• Abnormal conditions in the
cochlea, cochlear nerve,
auditory pathways,
auditory cortex

Mechanisms: Evidence for Central Site
• Auditory nerve section (Darby, 1941; House
and Brachmann, 1981)
• Near-normal hearing & tinnitus (highfrequency assessments)
Role of Affective State
• Folmer et al (1999) reported patients with
depression rated the severity of their tinnitus
higher although loudness scores were the
same.
• Interactions between tinnitus, stress, anxiety
and depression can be complex and dualdirectional (Andersson & McKenna, 1998;
Halford & Anderson, 1991)—principle to, or a
consequence of tinnitus
Drugs that may cause tinnitus
• Antiinflammatories
• Antibiotics
(aminoglycosides)
• Some
Antidepressants
(Benzodiazepines)
•
•
•
•
Aspirin
Quinine
Loop diuretics
Chemotherapeutic
agents (cisplatin,
vincristine)
History (TSCHQ)
• General Health: Infection,
illness, flu, or major life
changes
• Trauma (esp. with resultant
change in vision, hearing,
balance, memory/cognition,
patient’s own voice quality)
• Noise exposure Hx
• Medication usage
(Ototoxic, associated with
tinnitus genesis or potential
interaction suspected)
• Medical history (Cancer
treatment, systemic infection
or transplant recipient
• Vertigo
• Pain (ear, neck, jaw,
headache or with certain
sound-Hyperacusis)
• Family Hx
• Impact on patient
(sleeping?, depression?,
anxiety?)
• Tinnitus modulators neck
movement (flexion or
turning)/light compression,
jaw clenching, eye gaze,
facial movements
• Aggravators/alleviating
factors
• Hearing loss & laterality
• Tinnitus Characterization
• ONSET
• OTHER TREATMENTS
Audiological
• High-frequency audiometry (if speech-dominant range is normal) &
complaint of high-frequency tinnitus. N=192, Pitch-match most often to 9
or 10 kHz— (Shekhawat & Searchfield, 2011)
• Bone conduction (even if AC is normal) with complaint of autophony
+ Hx head trauma
• Otoscopy
• Acoustic Reflexes—May need to proceed with caution for tinnitus +
sound sensitivity
• Cochlear implants: Ito & Sakakihara (1994) N=26, For those
implanted who had tinnitus 77% reported tinnitus either abolished or
suppressed; 8% reported worsening
• CROS
• Consistent information (flip-books, websites)
• Outcome & quantifying measures (THI, TFI, TSNS, DASS)
Assessment & Referral
• Complete head & neck exam vascular or
musculoskeletal
• ENT/ORL
• Sleep specialist
• Counselling support
• Jaw specialist
• Review by Prescribing Physician
(Pharmacological)
• Audiology/Vestibular assessment
• Research
