What is a Eustachian tube balloon dilatation?

Eustachian tube balloon dilatation is a gentle, minimally invasive procedure designed to help people who suffer from chronic problems with their Eustachian tubes. The Eustachian tube is a small, narrow passage that connects the middle ear to the back of the nose. Its main job is to keep the air pressure in your middle ear balanced with the air pressure outside your body, which helps your eardrum move properly and allows you to hear clearly.

When this tube becomes inflamed or narrowed, it cannot open and close as it should. This procedure uses a tiny, specially designed balloon to stretch the opening of the tube, helping it to function normally again. Because the surgeon works entirely through the nose using a thin, lighted camera called an endoscope, there are no external cuts or scars on your face or ears.

Why Might I Need Eustachian tube balloon dilatation?

You may be offered this procedure if you have been struggling with persistent Eustachian tube dysfunction (ETD). This condition often causes a range of frustrating symptoms that can affect your daily life, including:

• A feeling of fullness or pressure in your ears.
• Muffled hearing or a sensation that your ears are blocked.
• Popping, clicking, or squeaking sounds inside your ears.
• Tinnitus (ringing or buzzing noises in the ear).
• Earache or discomfort.
• Dizziness or problems with your balance.

Doctors typically recommend this treatment when standard medical approaches have not provided enough relief. These might include using nasal steroid sprays, decongestants, antihistamines, or trying to "pop" your ears yourself (autoinflation). If these methods have failed to clear your symptoms, or if your condition has led to more serious issues—such as a "sucked in" eardrum (where the eardrum is pulled inward due to negative pressure), glue ear (fluid trapped in the middle ear), or repeated ear infections—this procedure can be a very effective way to restore your comfort and hearing.

What Happens Before Surgery?

The journey toward your procedure begins with a thorough consultation with an ENT (Ear, Nose, and Throat) specialist. During this visit, your consultant will review your medical history, discuss your specific symptoms, and perform a physical examination. They may also order diagnostic tests, such as hearing tests or scans, to ensure this procedure is the right choice for you.

Once the decision to proceed is made, you will attend a pre-operative assessment. This is a chance for the nursing team to check your general health, take your blood pressure, and confirm that you are fit for the procedure. You will be given specific instructions regarding your medications; for example, you may be asked to pause certain blood-thinning drugs.

On the day of your surgery, you will be given clear instructions about fasting. It is vital that you follow these rules strictly, which usually means having nothing to eat or drink for several hours before your arrival. This ensures your safety while you are under anaesthetic. When you arrive at the hospital, the nursing staff will settle you into your room, confirm your details, and prepare you for your trip to the operating theatre.

What Happens During Surgery?

The procedure is performed as a day-case, meaning you will usually go home on the same day. It is typically carried out under a short general anaesthetic, which means you will be asleep and feel no pain during the operation. In some cases, it may be performed under local anaesthetic, where the nose is numbed with a special spray and small injections so you remain awake but comfortable.

The surgery lasts about 30 minutes. Your surgeon uses an endoscope (a thin, flexible tube with a camera on the end) to get a clear view of the back of your nose. They then guide a small, deflated balloon catheter into the opening of the Eustachian tube. Once it is in the correct position, the balloon is gently inflated with saline (sterile salt water) to a pressure of about 10 to 12 bars. This pressure is held for approximately two minutes to carefully stretch and widen the tube. Finally, the balloon is deflated and removed. The surgeon may perform this on one or both sides, depending on your needs.

What Happens After Surgery?

Immediately after the procedure, you will be taken to a recovery area where the nursing team will monitor you closely as you wake up. Once you are fully alert and comfortable, you will be moved back to your ward. Most patients are ready to go home within one to two hours after the surgery.

For the first few days, you might feel some mild discomfort, but this is usually easily managed with simple painkillers like paracetamol. You may notice some temporary changes in your ear pressure or a feeling of fullness, which is a normal part of the healing process. To help your recovery, you should avoid heavy lifting, sneezing forcefully, or blowing your nose too hard for the first few days. You should also avoid performing the "Valsalva manoeuvre" (trying to pop your ears by blowing against a pinched nose) unless specifically advised otherwise by your consultant.

Most people feel well enough to return to work the day after the procedure. However, if you had a general anaesthetic, you must not drive for at least 48 hours. You will have a follow-up appointment with your ENT consultant about six weeks after your surgery to check your progress, followed by a telephone consultation at the six-month mark.

What are the Potential Risks and Complications?

While this is a low-risk procedure with a high success rate, it is important to be aware of potential complications. As with any surgery, there is a small risk of minor bleeding from the nose (epistaxis) or tenderness in the area. In rare cases, the procedure can lead to an ear infection or a small amount of blood collecting behind the eardrum (hemotympanum).

A very rare but known complication is surgical emphysema, where a small amount of air gets trapped under the skin of the head or neck. This usually resolves on its own without needing treatment. Other extremely rare risks include damage to the nerves or blood vessels near the area, which can lead to more serious issues like a transient ischemic attack (a temporary blockage of blood flow to the brain) or changes in heart rhythm. Your consultant will discuss these risks with you in detail during your pre-operative consultation to ensure you feel fully informed.

Long-Term Outlook

The goal of this procedure is to provide lasting relief from the symptoms of Eustachian tube dysfunction. While some patients notice an immediate improvement in their hearing and ear pressure, it is more common for the benefits to build gradually over the six weeks following the surgery as the inflammation settles and the tube begins to function more naturally.

Success rates for this procedure are generally high, ranging between 60% and 90%. By widening the tube, we aim to stop the cycle of blocked ears and discomfort that you have been experiencing. If you experience any concerning symptoms after you go home—such as severe pain, heavy bleeding that does not stop, or a sudden change in your vision or balance—please contact your hospital or seek medical advice immediately. Otherwise, we look forward to seeing you at your six-week follow-up to hear how much your ear comfort has improved.
