tinnitus ultrasound explained

Overview

Tinnitus is when you hear a sound — like ringing, buzzing, or hissing — that is not coming from outside. An ultrasound scan is a safe, painless imaging test that uses high-frequency sound waves to create real-time pictures of the inside of the body. In the context of tinnitus, ultrasound is sometimes used to look at the blood vessels in the neck and around the ear, to check for a vascular cause — especially if your tinnitus pulses with your heartbeat (pulsatile tinnitus).

Tinnitus is very common. Around one in eight adults experience persistent tinnitus, and many more have it temporarily. Ultrasound itself is a common, safe test that has been used in medicine for many years.

Tinnitus can affect people of all ages, but it is more common in older adults. It can also affect children. Ultrasound may be used in people who have pulsatile tinnitus or signs of a blood vessel problem.

Symptoms

Common symptoms

• Ringing, buzzing, hissing, whistling, or clicking sounds in one or both ears
• Sounds that are constant or come and go
• Sounds that change in loudness or pitch
• A feeling that the sound is 'inside' the head
• Difficulty concentrating or sleeping because of the sound

Symptoms in children

• Children may describe the sound differently, such as a 'cricket' or 'high-pitched whistle'
• They may seem distracted, ask 'what is that noise?' or have trouble paying attention
• They may rub or tug at their ears

Symptoms in older adults

• Tinnitus is more common with age and often linked to natural hearing loss
• It may be accompanied by difficulty hearing conversations, especially in noisy places
• Pulsatile tinnitus in older adults may indicate blood vessel changes that need checking

Causes

Main causes

• Hearing loss from noise exposure or ageing
• Earwax build-up or an ear infection
• Changes in the blood vessels near the ear — this can cause pulsatile tinnitus
• Certain medicines that may damage hearing (ototoxic drugs) — but do not stop or change any medicine without speaking to your doctor
• Temporomandibular joint (jaw) problems
• Head or neck injuries

Risk factors

• Increasing age
• Loud noise exposure — at work or at leisure
• High blood pressure or heart disease
• Diabetes
• Ear infections or earwax blockage
• History of head or neck injury

When to see a doctor

See a doctor urgently if:

• If you have pulsatile tinnitus (hearing a pulse in your ear), you should see a doctor soon to check for a blood vessel problem
• If tinnitus affects only one ear, or if it is accompanied by hearing loss, dizziness, or imbalance
• If you have recently started a new medicine and tinnitus began after that

Book a routine appointment if:

• If tinnitus is persistent and bothers you
• If it interferes with sleep, concentration, or daily activities
• If you want to learn about management strategies

Diagnosis

Your doctor will start by asking about your medical history and about the sound you hear — when it started, how often it happens, where you hear it. They may look in your ears with an otoscope and test your hearing. If they suspect a blood vessel cause, they may refer you for an ultrasound scan of the neck or head.

Tests that may be done

• Physical examination of the ears
• Hearing test (audiometry)
• Ultrasound scan of the neck with Doppler — this checks blood flow in the carotid and vertebral arteries
• Sometimes CT, MRI, or other scans — but these are used less often and only when needed

What to expect at your appointment

An ultrasound scan is quick and painless. You will lie down on a bed, and a small handheld probe with gel will be moved over your neck or around your ear. The probe sends harmless sound waves into your body, which create moving images on a screen. You will not feel anything except light pressure. The scan usually takes about 15–30 minutes. Afterwards, you can go back to normal activities immediately.

Treatment

Treatment for tinnitus depends on the cause. If a blood vessel problem is found on ultrasound, your doctor will discuss appropriate management. For most cases of tinnitus, there is no single cure, but there are many ways to make it less intrusive. Your doctor will help you find a plan that suits you.

Self-care at home

• Protect your ears from loud noise — use ear protection in noisy environments
• Keep background sound low – using a fan, music, or a sound machine at night can help mask the sound
• Manage stress with relaxation techniques, breathing exercises, or mindfulness
• Limit or avoid stimulants like alcohol and caffeine, as these can make tinnitus worse for some people
• Check your jaw – if you clench or grind your teeth, discuss treatment with your dentist

Medical treatments

Medical management may include hearing aids if you have hearing loss, sound therapy or masking devices, and cognitive behavioural therapy (CBT) to help change the way you respond to tinnitus. Your doctor will decide which approach is right for you. Medications are not licenced specifically for tinnitus, but your doctor may treat underlying conditions such as anxiety or insomnia. Always speak to your doctor before starting any treatment.

When is surgery considered?

Surgery is rarely needed for tinnitus itself. In some cases where ultrasound finds a clear vascular abnormality that can be corrected, such as a specific vein or artery issue, a surgeon or interventional radiologist might discuss options with you. Your specialist will explain the benefits and risks before you decide.

Living with this condition

Living with tinnitus is about finding ways to make the sound less noticeable. A good routine with regular sleep, exercise, and stress management can make a big difference. Having a clear explanation of your tinnitus and what it does — and does not — mean will help you feel in control.

Lifestyle tips

• Keep a regular sleep pattern and avoid screen time just before bed
• Use a low-level background sound at night to distract from tinnitus
• Stay active and exercise regularly — physical activity improves blood flow and mood
• Cut down on alcohol, caffeine, and smoking
• Join a local tinnitus support group or online community

Diet and exercise

A healthy, balanced diet with plenty of fruit, vegetables, and whole grains supports overall health. Regular exercise, such as walking or swimming, helps reduce stress and can improve circulation. There is no specific 'tinnitus diet', but staying well-hydrated and eating regular meals can help you feel better.

Mental health and emotional wellbeing

Tinnitus can be distressing and can disrupt sleep and mood. It is normal to feel frustrated, anxious, or even depressed. If tinnitus is affecting your mental health, talk to your doctor. Cognitive behavioural therapy (CBT) and mindfulness-based therapy can be very helpful.

Prevention

Tinnitus itself cannot always be prevented. However, you can reduce the risk of some causes by protecting your ears from loud noise, managing blood pressure and diabetes, and treating ear and jaw problems promptly.

Vaccines

There is no vaccine for tinnitus. However, staying up to date with recommended vaccines can help prevent infections that may lead to ear problems.

Screening programmes

There is no routine screening test for tinnitus. If you notice new or unusual tinnitus, it is best to have your ears and hearing checked.

Complications

If left untreated

• Untreated underlying conditions, such as high blood pressure or hearing loss, may continue to worsen
• Tinnitus can cause sleep problems, poor concentration, and increased stress or anxiety
• In rare cases, a vascular problem that causes pulsatile tinnitus could be a sign of something needing treatment – that is why investigation is important

Long-term outlook

For most people, tinnitus improves over time or becomes less bothersome, even if the underlying sound remains. With the right support, you can learn to live well with tinnitus.
