What Is The Main Cause Of Tinnitus

Tinnitus is a common condition in which a person hears sounds that are not present in the environment. These sounds are often described as ringing, buzzing, hissing, clicking, whistling, or sizzling. They may be heard in one ear or both, and can range from mild background noise to overwhelming, persistent sound.

For some people, tinnitus is occasional and manageable; for others, the intensity can make daily activities, work, and concentration difficult. It is often associated with some degree of hearing loss and may be accompanied by pressure or fullness in the ear.

Understanding the causes of tinnitus, risk factors, and treatment options is vital for effective management.

People frequently ask: What is the main cause of tinnitus?

There is no single cause. Instead, tinnitus can develop for a range of reasons, many of which involve the ear or auditory pathway. One of the most common causes is exposure to loud noise, which can damage tiny hair cells in the inner ear. Another major contributor is age related hearing loss.

The causes of tinnitus include:

Less commonly, tinnitus may indicate a more serious underlying condition, such as an acoustic neuroma, also known as vestibular schwannoma, a benign tumour affecting nerves responsible for hearing and balance.

Certain factors may increase the likelihood of developing tinnitus.

Risk factors of tinnitus include:

If you experience persistent tinnitus and have any of these risk factors, it is advisable to speak with a healthcare professional.

A key question many patients ask is: Do you have tinnitus for life?

The answer depends on the underlying cause. In some cases, tinnitus is temporary for example, after exposure to loud noise or following an ear infection. When the cause is addressed, symptoms may improve or resolve.

However, if tinnitus is linked to permanent hearing loss or chronic conditions, symptoms can persist long term. Even in cases where tinnitus does not disappear completely, many people find relief through therapies, lifestyle adjustments, and specialist treatments.

Although tinnitus is commonly related to hearing loss or benign ear conditions, diagnostic imaging may be recommended to rule out more serious causes.

An MRI of the internal auditory meatus (IAM) can help detect an acoustic neuroma (vestibular schwannoma). These benign tumours are rare but can cause tinnitus, hearing loss, or balance problems.

MRI IAM scans are:

If an acoustic neuroma is found, your doctor can refer you to a specialist for further management. If no abnormality is present, which is the case for most people, an alternative treatment approach can be explored.

Pulsatile tinnitus is a specific form of tinnitus that produces a rhythmic pulsing or whooshing sound in one or both ears. Unlike typical tinnitus, it often aligns with your heartbeat.

The causes are more complex and may involve blood flow issues or structural abnormalities. Pulsatile tinnitus usually requires specialist imaging, beyond a standard MRI IAM scan. If you experience pulsatile tinnitus, Vitalscan recommends seeking an ENT specialist’s opinion.
