39
HL & tinnitus
Most common cause of severe tinnitus - deprivation of sensory input to CANS Tinnitus is 2x as common in older adults than young adults - potential link to age-related HL and other health issues
40
tinnitus causes HL
FALSE HL can lead to tinnitus BUT tinnitus doesn’t cause HL
41
NIHL & tinnitus
Second most common of HL Exposure to hazardous levels of occupational or recreational noise Severity of NIHL: influenced by duration, intensity and energy content of the noise At risk: military personnel & industrial/recreational noise
42
who are at risk for NIHL & tinnitus
military personnel & industrial/recreational noise
43
serverity of NIHL
influenced by duration, intensity and energy content of the noise
44
possible cuases of menieres disease
ncreased endolymph pressure, rupture of Reissner’s membrane, & loss of hair cells
45
management of meniere's
primarily focused on vertigo and HL with less attention on tinnius
46
what is experienced in menieres
Tinnitus often LF tone (125-250 Hz)
47
common symptoms of vestibular Schwannoma & Cerebellopontine Angle Lesions
Common symptoms unilateral/assymetric HL Loss of balance Dizziness Facial numbness Tinnitus here has higher severity and annoyance levels
48
OTSC and tinnitus
Tinnitus is common High-pitched or resembles white noise First symptom Can initially be pulsatile
49
how does OTSC cause tinnitus
CHL = deafferentation Reduction of masking effect Rich blood supply = 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
50
ototoxicity & tinnitus sound
Continuous high-pitched sound
51
what drugs is tinnitus a side effect for
Salicylates (e.g., Aspirin), non-steroidal anti-inflammatory drugs (NSAIDs), Quinine, Aminoglycoside antibiotics, loop diuretics (e.g., Furosemide), chemotherapeutic agents (e.g., Cisplatin and Carboplatin)
52
examples of ototoxic drugs
Salicylates (e.g., Aspirin), non-steroidal anti-inflammatory drugs (NSAIDs), Quinine, Aminoglycoside antibiotics, loop diuretics (e.g., Furosemide), chemotherapeutic agents (e.g., Cisplatin and Carboplatin)
53
Most drug-induced tinnitus is reversible if drug is discontinued
true
54
what drugs cause permanet hl
aminoglycoside antibiotics, cisplatin, carboplatin) or prolonged high-dose use of salicylates.
55
describe synergistic effects
significant increase to the risk of hearing damage beyond what either factor would cause alone A combined exposure to noise & aminoglycosides = greater auditory damage More than either of them alone
56
stress & tinnitus
High stress = severe tinnitus Stress can worsen tinnitus in those that already have it OR it can induce tinnitus on its own
57
what is pulsatile tinnitus
In sync with the heartbeat Rhythmical noise usually the same beat as the heart Usually caused by bloodflow changes near the ear or by a change in awareness of the blood flow Whooshing sound with a constant rhythm
58
what is heard with pulsatile tinnitus
Whooshing sound with a constant rhythm
59
causes of pulsatile tinnitus
Venous hums Stenosis of carotid arteries Heart murmur Hypertension Hyperthyroidism Vascular stenosis Aneurysms Coronary artery disease
60
Unilateral head or neck pain with abrupt tinnitus onset
carotid dissection
61
Tinnitus intensity changes with head movement
venous source
62
what hx is important for pulsatile tinnitus
Ask about meds related to blood pressure & hx of heart disease or BP issues If they are taking meds is their BP under control or variable? Ask about previous imaging studies carotid/vertebral ultrasound, MRA, CTA PTs hx can give clues to the source of pulsatile tinnitus Abrupt onset with unilateral neck or head suggests a carotid dissection Changes in tinnitus intensity with head turning suggests venous source for tinnitus
63
what evaluations should be done for 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
64
Glomus jugulare Symptoms
Slow growing, late diagnosis until tumor is extensive (avg around 6 years from first symptom) HL is main presenting feature due to ME invasion Pulsatile tinnitus, ME mass, CN involvement, vertigo, otorrhea Rising sun appearance in otoscopy; red ™ Pulsatile tinnitus & decrease amp with carotid pressure PTA - unilateral CHL or mixed HL
65
what is clicking tinnitus
Rare Can be objective; somatosounds Not all are detectable by the examiner This appears to be due to contractions of the tensor tympani or the nasopharyngeal muscles controlling the patency of the ET
66
Clicking can be a symptom of
ME myoclonus (jerking of a muscle group)
67
Bilateral clicking is usually associated with
palatal myoclonus
68
things to ask for case hx for clicking tinnitus
What does it sound like? Clicking of a pen? When did it start? Is it progressing? One or both ears? (usually one ear) Random or does it coincide with some movement they do Does it get better or worse with position changes or changing head movements
69
what testing can be done for clicking tinnitus
Can see abnormalities during impedance testing Can be detectable using ARTs or reflex decay; will occasionally see it on tymps Sometimes reflexes are too short in duration so you can capture it during reflex decay testing Have PT tap leg when clicking is heard and look for corresponding results to te PT tap True clicking is likely caused by ME muscle spasms REFER to ENT
70
characteristic features of somatosensory tinnitus
Closely associated with factors related to the head or upper neck Tinnitus always perceived in the ear ipsilateral to the somatic event High pitched and constant ringing No other hearing or vestibular complaints & neurological exams show no abnormalities Hearing sensitivity is normal
71
causes of somatosensory tinnitus
muscle tension tmj/jaw issues dental disorders head injuries cervical spine issues chronic stress
72
case hx questions to ask
Any jaw issues currently or in the past Any clenching or grinding teeth Any jaw pain/poppin gon either side Any tightness in jaw or fatigue while chewing
73
diagnostic criteria/characteristics for somatic tinnitus
tinnitus increases with bad psture pitich, loudness and/or location vary teeth clenching dental diseases TMJ tinnitus preceded by head or neck trauma
74
what are clinical assessments that can be done for somatic tinnitus
TMJ - Have PT clench jaw for 10 s. Any change in tinnitus? Have PT open jaw wide/protrude jaw for at least 5s. Any change in tinnitus? neck maneuvers: Active neck movements - with and without resistance Passive muscular palpation in order to search for myofascial trigger points (MTP) or tender points
75
what are some red flags of tinnitus and should you refer
REFER for all Pulsatile tinnitus Tinnitus in association with vertigo Unilateral tinnitus or hearing loss Examination showing abnormalities of the ears Tinnitus in association with asymmetric hearing loss Psychological distress Significant associated sleep / concentration problems Anxiety regarding possible underlying pathology Distressing tinnitus not improving, despite initial treatment Patient request for ENT/audiological assessment Tinnitus in association with significant neurological symptoms
76
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 migraines and comes and goes with certain things) Maneuver relaxed the muscle which is why it could’ve decreased the intensity
77
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 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.
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 brain perceives it as a new stimulus) Value of digging into history of PT He has normal hearing What referral should be considered for this PT? Mental health services to deal with the stress and this might change the vicious cycle
78
Most common sound a patient will report for tinnitus is
ringing
79
pushing/whoosing Does it match your heartbeat Count the beats you feel and at the same time ask the PT to count the number of tinnitus beats they hear
pulsatile
80
Confirmed with tone decay because it provides a larger time window where as 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
81
Related to muscle spasms, etc. Do maneuvers to confirm this
somatosensory
