Tinnitus — causes and treatment
Tinnitus is the perception of sound in the ear (or in the head) without an external source. Although it can’t always be completely eliminated, proper diagnosis combined with several therapies can significantly reduce the burden and teach the patient to live without stress from the symptom.
What is tinnitus
Tinnitus is a perceptual phenomenon — the patient hears sound (whistling, hissing, pulsing, ringing) without any external source. We distinguish:
- Subjective tinnitus — most common; only the patient hears it. Linked to damage to the auditory system.
- Objective tinnitus — rare, but can be heard with an ENT exam (stethoscope). Most often vascular or muscular in origin.
- Pulsatile tinnitus — synchronized with the heartbeat; a vascular cause should always be ruled out.
- Non-pulsatile — continuous, most often related to hearing damage.
The most common causes of tinnitus
Hearing damage (presbycusis, acoustic trauma)
The most common cause — more than 80% of cases. Tinnitus arises from damage to the sensory cells in the inner ear. Acoustic trauma can be a one-time event (explosion, concert) or chronic (working in noise, prolonged loud music through earbuds).
Otosclerosis
A disorder of the ossicles of the middle ear. Characterized by gradual hearing loss + tinnitus, more common in women, starting between ages 20 and 40. Treatment is surgical (stapedectomy).
Ménière’s disease
The classic triad: tinnitus + hearing loss + vertigo attacks. The cause is an endolymph imbalance in the inner ear.
Ototoxic medications
Certain medications can damage hearing and cause tinnitus: aminoglycoside antibiotics, high-dose aspirin, some diuretics, chemotherapy agents (cisplatin). If you take such medications and develop tinnitus — contact your doctor; the regimen may need to be changed.
Vascular causes (pulsatile tinnitus)
High blood pressure, atherosclerosis, carotid artery anomalies, arteriovenous malformations. Pulsatile tinnitus is always investigated to rule out these causes.
Acoustic neuroma
A benign tumor of the auditory nerve. Rare but important to rule out: gradual unilateral hearing loss, unilateral tinnitus, sometimes vertigo. Diagnosed by MRI.
Other causes
- Earwax — tinnitus often resolves with simple wax removal from the ear canal
- TMJ dysfunction — jaw joint problems can produce “tinnitus”
- Stress, anxiety, depression — do not cause tinnitus directly, but amplify perception and distress
- Caffeine, alcohol, nicotine — can worsen symptoms
⚠️ When tinnitus signals a more serious problem
These signs warrant prompt diagnosis — we recommend not waiting:
- Unilateral tinnitus with hearing loss
- Pulsatile tinnitus synchronous with the heartbeat
- Sudden onset (overnight)
- Accompanied by vertigo or hearing loss
- Severe enough to disrupt work / sleep and quality of life
Diagnostics
Tinnitus isn’t a diagnosis — it’s a symptom. Our job is to find what is causing it and whether it can be treated. We use:
- Otomicroscopy — examines the external and middle ear (cerumen, perforation, infection)
- Audiometry — measures hearing across all frequencies; often reveals latent damage the patient hadn’t noticed
- Tympanometry — middle-ear and Eustachian tube function
- OAE (otoacoustic emissions) — tests the function of the outer hair cells in the cochlea
- Endoscopic exam — when tinnitus is pulsatile or a vascular cause is suspected
- MRI — recommended for unilateral tinnitus or suspected acoustic neuroma
How tinnitus is treated
Realistically: tinnitus is often chronic, and complete cure isn’t always possible. But a combination of strategies can significantly reduce the burden.
Treating the underlying cause
If the cause is cerumen — removal often resolves the tinnitus immediately. If it’s high blood pressure or an ototoxic medication — correcting the cause helps. If it’s otosclerosis — surgical treatment.
Tinnitus retraining therapy (TRT)
A combination of counseling and sound therapy (maskers or broadband sound). The goal is to “retrain” the brain to ignore the tinnitus. Effectiveness: 60–80% of patients report significant improvement.
Cognitive behavioral therapy (CBT)
When tinnitus is exacerbated by stress, anxiety, or insomnia, psychological therapy is an important part of treatment. The tinnitus itself doesn’t decrease, but its impact on quality of life is significantly reduced.
Hearing aids
In patients with hearing loss, a hearing aid often reduces tinnitus because the brain again receives “normal” auditory stimulation.
💡 What you can do
- Avoid silence — background sound (nature, ocean noise) significantly eases nighttime
- Reduce caffeine, alcohol, tobacco — they worsen symptoms in many patients
- Learn relaxation techniques (meditation, yoga, breathing) — stress amplifies perception
- Protect your hearing — always wear earplugs at concerts, loud events, at work
- Don’t isolate yourself — patients who stay active often forget about the tinnitus
