Intratympanic steroid injection is a specialised treatment used to manage severe or persistent symptoms of Menieres disease. When conservative treatments like a low salt diet and oral medications fail to control vertigo attacks, an ENT specialist may recommend injecting steroids directly into the middle ear. In the UK, this procedure has become a popular second line treatment because it is effective at reducing the frequency of vertigo without the high risks to hearing associated with more aggressive surgical options.
The goal of the steroid injection is to reduce inflammation within the inner ear and stabilise the chemical balance of the fluid that causes Menieres symptoms. Because the medication is delivered locally, it can achieve a high concentration where it is needed most while avoiding the systemic side effects of oral steroids. This makes it a valuable tool for patients who need more intensive management to regain their quality of life.

When a steroid injection becomes necessary
It is also used as a rescue treatment for sudden drops in hearing, which can sometimes occur during a Menieres flare up. By delivering the steroid directly through the eardrum, clinicians can target the inflammation quickly. This approach is particularly favored for patients who still have functional hearing in the affected ear, as steroids are protective of the delicate hearing cells rather than destructive.
How the procedure is performed
An intratympanic steroid injection is a relatively quick procedure that is typically performed in an outpatient ENT clinic. You do not usually need a general anaesthetic. The clinician will first numb the eardrum with a local anaesthetic spray or cream. Once the area is numb, a very fine needle is used to inject a small amount of steroid solution, such as dexamethasone, through the eardrum into the middle ear space.
After the injection, you will be asked to lie still with your head turned to one side for about twenty to thirty minutes. This allows the medication to be absorbed through a small membrane called the round window, which leads directly into the inner ear. You may need a series of two or three injections over several weeks to achieve the maximum benefit.
Efficacy and expectations
The effectiveness of steroid injections for Menieres varies between patients, but many clinical studies show that up to 50 to 70 percent of people experience a significant reduction in the frequency and severity of their vertigo attacks. While it is not a permanent cure, the relief can last for several months or even years.
One of the main reasons this treatment is preferred over gentamicin injections is safety. Gentamicin is an antibiotic that can permanently damage hearing, whereas steroids are considered hearing neutral. If the steroid injections provide relief, they can be repeated safely if symptoms return in the future. This makes them an excellent option for long term management in patients who want to preserve their remaining hearing for as long as possible.
Comparison: Steroid Injections vs Gentamicin
| Feature | Intratympanic Steroid | Intratympanic Gentamicin |
| Primary Goal | Reduce inflammation | Disable balance organ |
| Effect on Hearing | Safe or protective | Risk of permanent loss |
| Vertigo Control | Moderate to High | Very High |
| Clinical Timing | Second line treatment | Reserved for severe cases |
| Procedure Type | Clinic based injection | Clinic based injection |
| Recovery Time | Very fast | Several days of dizziness |
| Repeatable | Yes safely | Only with extreme caution |
To Summarise
Steroid injections are a vital second line treatment for Menieres disease when standard lifestyle changes and oral medications are not enough. By delivering powerful anti inflammatory medication directly to the inner ear, specialists can often stop or reduce the frequency of debilitating vertigo attacks while keeping the patients hearing safe. For many people in the UK, this procedure represents a turning point in their treatment, offering a way to manage symptoms that previously felt uncontrollable.
If you experience sudden vertigo accompanied by a severe headache, difficulty speaking, or weakness on one side of your body, call 999 immediately.
Does the injection hurt?
Most patients describe the sensation as a brief pressure or a slight sting when the numbing agent is applied, but the injection itself is usually well tolerated because the eardrum is numbed beforehand.
How soon will I notice an improvement?
It can take a few days or even a couple of weeks for the steroid to fully take effect. You may not notice a significant change until after the second or third injection in a series.
Are there any risks to the eardrum?
There is a very small risk that the tiny hole made by the needle may not heal on its own, but this is rare. In most cases, the eardrum heals completely within a few days.
Can I drive home after the injection?
It is usually recommended that you have someone drive you home. The procedure can occasionally cause a brief moment of dizziness or a feeling of fullness in the ear that might make driving uncomfortable.
How long do the effects of the steroid last?
The duration of relief varies. Some patients remain attack free for several months, while others may find that their symptoms stay under control for a year or more before needing another treatment.
What if the steroid injections don’t work?
If steroids do not control the vertigo, your ENT specialist may discuss other options such as gentamicin injections, endolymphatic sac surgery, or other surgical interventions.
