From Latin tinnire ( to ring or tinkle )- a sensation of any sound perceived in the head or in the ears without 
an evident external stimulus.

At any point in time around 10 % of the population experiences tinnitus ( BTA ) There is no standard diagnostic criterion for tinnitus and is normally determined by self -report typically in reponse to a single question Tinnitus has a reported prevalence of about 8-25.3 % in the US A systemic review ( Abby McCormack et al 2016 ) reported a range from 5.1 to 42.7 % No gender discrimination in incidence Higher incidence among- military personnel, stage workers , drummers and those who perform in front of loudspeakers

Subjective tinnitusOccurs in absence of any physical sound reaching 
the ear – audible only to the patient. Causes- wax in external ear . Middle ear causes – otosclerosis , middle ear effusion

Inner ear causes –Noise-induced hearing loss Presbyacusis Meniere’s dis Trauma ( surgery , head injury ) Ototoxic drugs Labyrinthitis Acoustic neuroma

Two-thirds of people with tinnitus have a disorder causing hearing impairment Most commonly tinnitus is associated with disorders causing sensorineural hearing loss- includes
○ age related
○ noise related ( less common )
○ Meniere’s dis ( uncommon ) Less commonly tinnitus is associated with disorders causing conductive hearing loss
○ wax
○ otosclerosis ( rare ) Ototoxic drugs ( uncommonly ) Ear infections – including
○ otitis media
○ otitis media with effusion
○ chronic suppurative otitis media Neurological disorders
○ acoustic neuroma
○ multiple sclerosis Metabolic disorder – thyroid disease and diabetes Psychological →anxiety and depression Trauma of the head or neck

Objective tinnitus Generated in the body and reaches the ear through conduction in body tissues and is audible to the patient as well as the clinician 
( also called somatosounds ).High cardiac output
○ treatment of hypertension with ACEi’s or CCB’s Benign intracranial hypertension Dural or extracranial AV fistula Carotid or vertebral artery stenosis , tortuosity , dissection or aneurysm Aortic dissection and mitral regurgitation Dural or cervcal AVM ( arteriovenous malformation ) High jugular bulb Vestibular schwannoma Temporomandibular joint syndrome Haemangioma Glomus tumour Otosclerosis Paget’s disease. Has a vibratory , clicking or pulsatile character
 Audible with a stethoscope
○ place the stethoscope close to external auditory meatus over the carotid arteries , and on the skull in front and behind th ear. If patient c/o pulsatile tinnitus – clinician should conduct extensive search for a skull base tumour
 Numerous vascular causes of pulsatile tinnitus
most common being 
○ arteriovenous malformations ( AVM ) and 
○ fistulas
 Benign intracranial hypertension has been reported as a major cause of pulsatile tinnitus in toung women

HistoryNo known objective tests that can determine the severity of subjective tinnitus
 unilateral or bilateral constant or intermittent triggers around onset when did it start become annoying associated symptoms
○ deafness
○ dizziness
○ hyperacusis
○ otalgia h/o sig noise exposure drug history ( ototoxic drug use ) family h/o hearing loss from otosclerosis 
Otosclersosis → bone around the base of stapes becomes thickened and eventually fuses with the bone of cochlea → reduces normal sound transmission leading to conductive hearing loss effect on life psychological

Examination Otoscopy
○ wax
○ infections Tuning fork tests ( conductive or sensory hearing loss ) Bedside hearing test General neurological assessment
○ acoustinc neuroma
○ multiple sclerosis Check blood pressure Blood tests
○ hypo and hyperthyroidism
○ random or fasting BM Auscultate ears , head and neck if pulsatile tinnitus
○ exclude bruit Fundoscopy ( benign intracranial hypertension ) Refer for formal hearing test
○ pure tone audiometry with assessment of air and bone conduction MRI- for vestibular schwannoma ( acoustic neuroma )

Red flags Sudden onset pulsatile tinnitus Tinnitus in association with significant/severe vertigo Unilateral tinnitus Tinnitus in association with asymmetric hearing loss or tinnitus with unexplained sudden hearing loss Tinnitus in association with significant neurological symptom and or signs Tinnitus following head trauma Tinnitus causing psychological distress

Hearing testArrange a hearing test for all patients with tinnitus- CKS advice’s an audiology referral if tinnitus persists for tinnitus that lasts 6 months or more

Twenty percent of persons visiting tinnitus clinics have normal hearing

Tinnitus associated with conductive hearing loss → when a clear cause is found eg wax or otitis media
 B/L tinnitus associated with sensorineural hearing loss when
○ non occupational noise related hearing loss can be confidently diagnosed
○ age related hearing loss can be confidently diagnosed

Treat underlying cause Explain
○ tinnitus is common and usually improves with time by process of habituation
○ goal of treatment is to reduce impact on daily life
○ sef help is often effective Ask and address anxiety , depression , insomnia
○ consider pharmacology Adv about sound enrichment
 ( reduce impact ) Hearing aid CBT Tinnitus retraining therapy White noise ( masking ) Neuromonics Biofeedback Surgery Support groups

Referral ENT Objective tinnitus Subjective tinnitus and a formal hearing test shows
○ unilateral tinnitus associated with sensorineural hearing loss- includes people with suspected
 ♦ Acoustic neuroma
 ♦ Meniere’s dis B/L tinnitus associated with sensorineural hearing loss – suspected occupational noise-induced hearing loss → person eligible for compensation Tinnitis associated with conductive hearing loss with no clear cause. includes
○ Otosclerosis ( one or both ears )
○ Cholesteatoma
○ Otitis media with effusion
○ Chronic suppurative otitis media Secondary to head or neck injury Uncertain cause Tinnitus causing distress despite primary care management

British Tinnitus Association top tips for GPsMost tinnitus is mild An underlying pathology is rare but be vigilant Tinnitus can be associated with a blocked sensation in ears ( cause is not clear ) Giving a negative prognosis is actively harmful There is no direct role for drugs Referral routes vary according to local protocols Tinnitus is more common in people with hearing loss- hearing aids can be helpful Having some continuous low level unobtrusive sound in the background can reduce the starkness of tinnitus Self-help is often effective ( see under links & resources )
