Balloon dilation for Eustachian Tube Dysfunction

Dr. med. Florian Bast


Eustachian tubes are small tubes that run between the middle ears and the post nasal space. They are responsible for equalising ear pressure as well as draining and protecting the middle ear. The eustachian tubes are usually closed except when chewing, swallowing, or yawning.

These passageways are small in size and can become plugged for a variety of reasons. Blocked eustachian tubes can cause pain, hearing difficulties, a feeling of fullness in the ears, dizziness, popping sounds and tinnitus.  Such a phenomenon is referred to as Eustachian Tube Dysfunction (ETD).

ETD is a relatively common condition.  Depending on the cause, it may resolve independently, or through simple at-home treatment measures.  Severe, recurring and chronic cases may require a visit to the doctor.

The length of time that ETD symptoms last depends on the initial cause. Symptoms from altitude changes, for example, may resolve once you return to the altitude with which you are acclimatised whereas illness and other causes of ETD may result in longer-lasting symptoms.

The most common causes of ETD are allergies, chronic rhinosinusitis and the common cold. These conditions may cause your eustachian tubes to become inflamed or clogged with mucous.

Activities such as traveling at high altitude, flying on a plane, scuba diving, and simply taking an elevator or riding the underground train,  all of which involve a change in altitude, may elicite symptoms of ETD.

Endoscopic balloon dilation for ETD is the first technique that truly treats the cause of the symptoms experienced, and recent studies have demonstrated superior symptom improvement compared with medical treatment (0% complication rate).

I performed the first endoscopic balloon dilation for Eustachian Tube Dysfunction in 2011 in Germany shortly after the device was approved for the German market.

The treatment may be performed under general anaesthetic, or local anaesthetic +/- sedation.

I am happy to explain the procedure and the diagnostic pathway in details in person.

Balloon Dilation for Sinus Problems

Dr. med. Florian Bast


Balloon sinus dilation is a minimally invasive technique for selected patients with chronic rhinosinusitis and barosinusitis.
The aims of balloon sinus dilation are:
• to provide relief from uncomfortable and painful sinusitis symptoms
• to unblock sinuses without invasive surgery

The treatment may be performed under general anaesthetic, or local anaesthetic +/- sedation.
Tiny balloons are carefully directed into the blocked sinus openings.
Once the correct position is confirmed, the balloon is inflated to high pressures to stretch the narrow channels.
The whole procedure takes only a few minutes. When performed under local anaesthetsia patients should only feel slight discomfort when the balloon is inflated.

What is barosinusitis?

Barotrauma of the paranasal sinuses is a risk factor for anyone exposed to ambient pressure changes.  These pressure changes most often result from travel through mountainous regions, flying, or diving.  Barosinusitis is characterised by inflammation of one or more of the paranasal sinuses. Inflammation is caused by a pressure gradient, almost always negative, between the sinus cavity and the surrounding ambient environment.
