Many people are familiar with ear syringing, but microsuction has become the preferred method of ear wax removal for many audiologists and ENT specialists. It is a precise technique that removes ear wax without the use of water.
Below, we explain what microsuction ear wax removal involves, why it is recommended, what you can expect during the procedure, and when an alternative approach or medical assessment may be more appropriate.
What microsuction ear wax removal actually is
Microsuction is a dry, water-free method of removing excess or impacted ear wax from the ear canal using a small, gentle medical suction device. Throughout the procedure, the clinician has a clear view of the ear canal using magnifying loupes and a bright light, or an ENT microscope.
This clear visualisation allows ear wax to be removed with precision and control. Because the ear canal and eardrum are delicate structures, being able to see exactly where the wax is helps minimise unnecessary contact with sensitive tissues and enables a more targeted approach than flushing the ear with water.
Why clinics often prefer microsuction over syringing
Traditional irrigation (syringing) uses water to flush wax out. It can be effective, but it isn’t suitable for everyone. Microsuction avoids putting water into the ear canal, which can be helpful in a range of situations.
Microsuction is commonly chosen when:
- You have a perforated eardrum: Water entering a torn eardrum causes severe pain and deep infections; microsuction keeps the middle ear dry.
- You have grommets or past ear surgery: These structural changes make water-based flushing unsafe.
- You are prone to ear infections: Microsuction avoids introducing moisture, preventing the damp environment where bacteria and fungi thrive.
- The wax is close to the eardrum: Continuous visualisation allows the clinician to remove deep wax precisely without touching delicate structures.
- You experience vertigo: Eliminating water removes the risk of triggering the inner ear’s temperature-sensitive balance reflex.
Not everyone is suitable for every method. The right approach depends on your ear health, symptoms, and what your clinician sees on examination.
How the procedure works step by step
People often imagine a strong vacuum. In practice, the suction is controlled and designed for medical use in the ear canal. The key difference is that it’s performed under continuous visual guidance.
First, your ear is checked
Your clinician will ask about symptoms such as blocked hearing, ringing (tinnitus), pain, discharge, dizziness, or a recent cold. They’ll also ask about past ear surgery, grommets, perforations, and whether you’ve tried to remove wax yourself.
They’ll then look in your ear using an otoscope or microscope to confirm whether wax is present and whether removal is appropriate on the day.
Then the wax is removed under magnification
You’ll sit still while a thin suction tube (cannula) is guided into the ear canal. The clinician positions it near the wax and uses gentle suction to lift it away. If the wax is very dry or stuck, tiny manual instruments may be used to loosen it in small pieces before suctioning it out.
Because the clinician can see the wax and the eardrum throughout, they can pause and adjust if you’re uncomfortable.
Finally, the ear is re-checked
Once the wax is cleared, the clinician will inspect the canal and eardrum again. If your symptoms don’t match what’s seen (for example, your ear looks clear but your hearing still feels reduced), that’s useful information. It may mean a hearing test, GP review, or ENT referral is needed.
What it feels and sounds like in the chair
The most surprising part for many people is the sound. Because the suction works close to the eardrum, it can be loud. Patients often describe a rushing, crackling, or whooshing noise.
In terms of sensation, it’s usually a mild pulling, tickling, or cool feeling. It should not be painful. If you do feel pain, tell the clinician immediately. Pain can suggest inflamed skin, infection, or that the wax is tightly impacted and needs a slower approach.
A less common reaction is a brief cough. There’s a nerve pathway near the ear canal (involving the vagus nerve) that can be stimulated during cleaning. It can feel strange, but it’s typically harmless.
What to expect after microsuction
Many people notice an immediate change in hearing clarity and a reduction in pressure. It can feel like “the ear opened up” straight away.
It’s also normal to have mild, temporary effects such as:
- A cool or airy sensation because air can move freely through the canal again once the blockage is gone.
- Mild dizziness for a few minutes as your balance settles from the sound or movement of the suction.
- Slightly sensitive hearing where environmental sounds seem overly loud for a few hours while your ears adjust.
- Minor irritation or dryness in the ear canal skin from the suction process.
If you develop increasing pain, discharge, or ongoing dizziness after the appointment, seek medical advice.
When to get checked instead of trying home removal
It’s tempting to use cotton buds or at-home kits when your ear feels blocked. The problem is that wax is often pushed deeper, and the ear canal skin is easy to injure.
Book an assessment promptly if you have ear pain, discharge, sudden hearing loss, one-sided hearing changes, or dizziness.
For adults, especially if you wear hearing aids, regular ear checks can help prevent small wax build-ups from turning into a full blockage.
