Tinnitus (ringing in the ears): Causes and clinical management.

Tinnitus (noise in the ears) is the perception of sound when no external source of sound exists. The sound may be described as whistling, ringing, humming, pulsing or hissing, and it may be present in one or both ears. Studies estimate that around 10 to 15 percent of adults experience persistent tinnitus. For many patients it becomes a deeply distressing condition that disturbs sleep, concentration and mood – but the good news is that effective management strategies exist today.

How does tinnitus arise?

In most cases, tinnitus begins with damage to the delicate sensory cells of the inner ear. When the brain receives fewer sound signals from the ear, it tries to compensate for the loss by increasing the sensitivity of its hearing centres – and it is precisely this heightened activity that is perceived as a phantom sound. This mechanism also explains why tinnitus becomes more noticeable in silence and during periods of stress and fatigue.

What are the most common causes?

Tinnitus is not a disease in itself, but a symptom of another underlying condition. The main causes include:

• Exposure to loud noise: Loud music, concerts and noisy workplaces damage the sensory cells of the inner ear – the most common and most preventable cause.
• Earwax blockage (cerumen): A physical obstruction that alters pressure and sound perception; it can be resolved immediately at the clinic.
• Age-related hearing loss (presbycusis): The natural decline of hearing after the age of 60 is very frequently accompanied by tinnitus.
• Middle ear infections and fluid: Treatable conditions that should be ruled out at the very first visit.
• Inner ear disorders: Ménière's disease, which is accompanied by vertigo and fluctuating hearing, or otosclerosis.
• Ototoxic medications: High doses of aspirin, certain antibiotics and diuretics can cause or worsen tinnitus.
• Vascular problems and hypertension: In certain cases the tinnitus pulses in time with the heartbeat – so-called pulsatile tinnitus, which always requires specialist evaluation.
• Jaw and neck disorders: Problems of the temporomandibular joint and muscular tension can influence how the noise is perceived.

When does tinnitus require urgent assessment?

Some forms of tinnitus call for examination without delay:

• Tinnitus in one ear only, especially when accompanied by hearing loss on the same side.
• Pulsatile tinnitus, beating in rhythm with your pulse.
• Tinnitus appearing together with sudden hearing loss – this is a medical emergency in which every day counts.
• Tinnitus accompanied by dizziness or balance problems.

How is it diagnosed?

Our assessment begins with microscopic otoscopy to exclude visible causes, continues with a full audiogram and tympanometry to measure hearing function precisely and, when specific signs are present, is completed with imaging studies. Identifying the cause is the key to successful management.

Can tinnitus be cured?

The answer depends on the cause. If the noise stems from earwax, an infection or a treatable middle ear problem, the solution is often immediate and definitive. If the source is damage to the inner ear, the tinnitus usually does not disappear completely – but that does not mean you cannot be helped. The goal of modern management is to teach the brain to filter the noise out, just as it filters out the hum of a refrigerator or traffic, until it no longer intrudes on your daily life.

Modern tinnitus management

• Hearing aids: When tinnitus is accompanied by hearing loss, amplifying natural ambient sounds masks the internal noise and gives the brain the stimulation it lacks – often with noticeable benefit within the first weeks.
• Sound generators (maskers): Devices or apps that produce soft background sounds (white noise, the sound of rain) to distract the brain, particularly helpful at night.
• Tinnitus retraining therapy (TRT): A combination of structured counselling and sound therapy aimed at habituation – the brain learns to classify the noise as unimportant.
• Psychological support and relaxation techniques: Cognitive behavioural therapy has strong scientific evidence for reducing distress and improving sleep in tinnitus patients.

What can you do yourself?

• Avoid absolute silence – a gentle background sound (quiet music, a fan) softens the perception of the noise.
• Protect your ears from loud noise and use hearing protection when needed.
• Limit caffeine and nicotine if you notice they make the noise worse.
• Manage stress and look after your sleep – fatigue amplifies tinnitus.

The most important thing is not to ignore the noise in your ears and not to face it alone. An early visit with an accurate audiogram is the first step towards regaining your peace and quiet.
