The Sound That Only You Can Hear
A ringing, buzzing, hissing, or whooshing sound that nobody else can hear – tinnitus affects approximately 10-15% of the adult population, and for some, it is a constant, distressing companion that affects sleep, concentration, mood, and quality of life. At our practice in Zürich Seefeld, I evaluate tinnitus systematically because while it is common, it sometimes signals a treatable underlying condition.
What Causes Tinnitus?
Noise exposure: The most common cause. Both acute noise trauma and chronic exposure damage the delicate hair cells of the inner ear, leading to altered neural signalling that the brain interprets as sound.
Age-related hearing loss (presbycusis): As hearing declines, the brain “fills in” the missing frequencies with phantom sound – tinnitus. This is why tinnitus and hearing loss so often coexist.
Earwax impaction: A simple, immediately treatable cause that should always be excluded.
Medications: Aspirin (high doses), certain antibiotics (aminoglycosides), loop diuretics, NSAIDs, and some chemotherapy agents are ototoxic (toxic to the ear).
TMJ dysfunction: Jaw joint problems can cause or worsen tinnitus due to the anatomical proximity and shared neural pathways between the TMJ and the auditory system.
Cervical spine dysfunction: Neck problems can influence tinnitus through somatosensory-auditory interactions.
Stress and anxiety: While not a direct cause, stress amplifies the perception of tinnitus and creates a vicious cycle – tinnitus causes stress, stress worsens tinnitus.
Vascular causes: Pulsatile tinnitus (rhythmic sound synchronised with the heartbeat) can indicate vascular abnormalities and warrants investigation.
When to Seek Medical Evaluation
Tinnitus that is unilateral (one ear only), pulsatile, sudden in onset, associated with hearing loss or dizziness, or significantly impacting your quality of life warrants medical evaluation. Unilateral tinnitus in particular should be investigated to exclude an acoustic neuroma.
Our Diagnostic Approach
I perform otoscopy (examining the ear canal), assess for hearing loss, evaluate the TMJ and cervical spine, review medications, check blood pressure, thyroid function, and iron levels (iron deficiency can worsen tinnitus). Referral for audiometry and ENT evaluation is arranged when indicated. For pulsatile tinnitus, vascular imaging may be necessary.
What We Do: Managing Tinnitus Effectively
Treat reversible causes: Earwax removal, medication adjustment, TMJ treatment, cervical physiotherapy, and correction of iron deficiency or thyroid dysfunction.
Sound therapy: Background sound (white noise, nature sounds, tinnitus apps) reduces the contrast between tinnitus and silence, making it less noticeable.
Hearing aids: When hearing loss coexists, hearing aids amplify external sounds, reducing the brain’s need to generate phantom sounds.
Cognitive Behavioural Therapy: CBT for tinnitus is the most evidence-based psychological treatment, helping to change the emotional response to tinnitus and break the distress cycle.
Stress management: Mindfulness, relaxation techniques, and sleep optimisation reduce the amplification of tinnitus by the stress response.
Nutritional support: Magnesium, zinc, and B vitamins may support auditory nerve function. Ginkgo biloba has mixed evidence but may help some patients.
Conclusion
Tinnitus is rarely dangerous but can significantly impact quality of life. A systematic approach to identifying treatable causes combined with evidence-based management strategies can provide meaningful relief. If tinnitus is bothering you, book an evaluation at our practice in Zürich Seefeld.
