Blocked ears are one of the most common reasons people walk into a hearing clinic. Sound goes dull, one ear feels full, the phone is harder to follow — and often the culprit is nothing more serious than ear wax.
Microsuction is the method most audiology clinics and ENT specialists now use to remove it. This article explains what microsuction actually involves, why it is generally considered the safest and most controlled option, and how it compares with syringing, drops and ear candling.
What Is Microsuction Ear Wax Removal?
Microsuction is the removal of ear wax using gentle medical suction, carried out under direct magnified vision. The clinician looks into the ear canal through a microscope or magnifying loupe and uses a fine, low-pressure suction tube to lift the wax out.
The key difference from older methods is visibility and control. Nothing is flushed blindly into the canal, no water is used, and the clinician can see the eardrum and the wax the entire time.
Why It Is Widely Regarded as the Safer Option
- It is done under vision. The clinician sees exactly what they are removing and where the eardrum is.
- It is water-free. No fluid is pushed into the ear canal, so there is no risk of water sitting behind a blockage or entering the middle ear.
- It suits ears that cannot be syringed. People with a perforated eardrum, grommets, a history of ear surgery, a mastoid cavity, or recurrent ear infections can usually still have microsuction.
- It is quick. Most appointments take only a few minutes per ear.
- Relief is immediate. Hearing usually improves the moment the blockage is cleared.
How Microsuction Compares With Other Methods
Method |
How It Works |
Main Drawbacks |
Microsuction |
Gentle suction under magnification, no water |
Can be noisy; needs a trained clinician and proper equipment |
Irrigation / syringing |
Warm water flushed into the canal to float the wax out |
Not done under direct vision; unsuitable with a perforation, grommets or previous ear surgery |
Wax-softening drops |
Oil or peroxide-based drops soften wax so it migrates out naturally |
Slow, often incomplete; can temporarily make a blockage feel worse |
Cotton buds |
Not a removal method at all |
Pushes wax deeper, can scratch the canal or damage the eardrum |
Ear candling |
A hollow candle burned near the ear |
No evidence it removes wax; carries a genuine risk of burns and canal injury |
Signs You May Have a Wax Blockage
- A blocked or full feeling in one or both ears.
- Muffled hearing that came on fairly suddenly.
- Earache or pressure without an obvious infection.
- Ringing or buzzing that started around the same time as the blockage.
- Hearing aids whistling more than usual, or feeling like they have stopped working properly.
- Dizziness or a mild off-balance feeling.
Wax that is not causing any of these does not usually need removing. Ear wax is normal and protective — it traps dust, keeps the canal skin healthy and migrates out on its own. The aim is to clear blockages, not to keep the ears permanently “clean”.
What Happens at a Microsuction Appointment
- A short history. Any ear surgery, perforations, grommets, infections, dizziness, blood thinners or diabetes — all worth mentioning.
- An otoscopy check. The clinician examines both canals and eardrums to confirm wax is the problem and that microsuction is appropriate.
- The procedure. You sit still while the clinician removes the wax under magnification. You will hear a vacuum-like noise, which is the most common thing people comment on.
- A final look. Both canals and eardrums are re-checked once clear.
- A hearing check if needed. If hearing is still not right once the wax is gone, that is worth investigating with a proper hearing test.
Does It Hurt?
Most people find it painless — odd, but not sore. The suction is loud, and hard wax pressed against the canal wall can feel briefly uncomfortable as it lifts away. Tell the clinician at any point and they will pause.
Should I Use Drops Beforehand?
If your wax is hard or impacted, a few days of olive oil or a pharmacy wax-softening drop before your appointment makes removal faster and more comfortable. Ask when you book — for softer wax it is often not needed.
Afterwards
- Hearing is usually clearer straight away, and can briefly feel unusually sharp.
- Some people notice mild ringing or a light-headed feeling for a short time.
- Keep cotton buds out — they are the most common cause of the next blockage.
- If you are prone to build-up, a maintenance routine or periodic check is easier than waiting for a full blockage.
See a GP promptly if you have ear pain that is getting worse, discharge, bleeding, sudden hearing loss in one ear, or persistent dizziness. Those need medical assessment rather than wax removal.
Who Should Be Extra Careful
Microsuction is suitable for most ears, including many that cannot be syringed. Let the clinician know beforehand if you have a perforated eardrum, grommets in place, a history of ear surgery or a mastoid cavity, an active ear infection, diabetes, a bleeding disorder or are taking blood thinners, or if you have significant tinnitus or noise sensitivity — the suction noise can be uncomfortable.
Frequently Asked Questions
How long does microsuction take?
The removal itself usually takes a few minutes per ear. Allow a short appointment overall, which includes the examination before and after.
Is microsuction safe for hearing aid wearers?
Yes, and it is particularly useful. Wearing hearing aids can slow the ear’s natural wax migration, so regular wearers build up wax more often. Clearing it usually restores both hearing and device performance.
How often should I have my ears cleared?
Only when wax is causing symptoms. Some people need it once or twice a year, many never need it at all. Routine “preventive” cleaning of healthy ears is not recommended.
Can microsuction damage my hearing?
Performed properly by a trained clinician under direct vision, it is a low-risk procedure. The suction is noisy while it is running, but the exposure is brief. Tell the clinician if the noise is distressing.
My hearing is still muffled after the wax is out. Why?
Wax may have been masking an underlying hearing loss. If clarity has not returned, book a diagnostic hearing test — the signs of hearing loss are easy to put down to something else.
