When it comes to ear wax removal, microsuction is widely considered the safest, most effective, and most comfortable method available. Unlike ear irrigation (flushing with water) or at-home interventions, microsuction is performed under direct microscopic visualisation by trained clinicians. Here's everything you need to know about it.
What Is Microsuction?
Microsuction is a wax removal technique that uses a surgical microscope to give the clinician a magnified, illuminated view of the ear canal and eardrum. A thin plastic suction catheter (a low-pressure tube) is then carefully introduced into the canal to gently remove earwax under direct vision.
Because the clinician can see exactly what they're doing at all times — rather than working blind or using a light without magnification — microsuction offers a level of precision and safety that other methods simply cannot match.
How Does It Work?
- Examination first: The clinician uses an otoscope or microscope to assess the ear canal and confirm the position and nature of the wax
- Suction setup: A low-pressure suction device is connected to a thin, flexible tube (the suction catheter)
- (The ear canal anatomy is carefully navigated — the canal is ~2.5cm long)
- Wax removal: The suction tip is gently advanced toward the wax, and the wax is drawn into the tube in a controlled manner. The clinician controls the suction strength and position throughout
- Check: The ear canal and eardrum are examined after removal to confirm complete clearance and check for any irritation or injury
What to Expect During the Procedure
How Long Does It Take?
For most people, a single ear takes 5–15 minutes. Both ears, if both are blocked, typically take 20–30 minutes. You can usually go about your day immediately afterward.
Does it hurt? Microsuction is generally described as mildly uncomfortable rather than painful. You may feel a strange suction sensation, some tickling, or occasional light tapping as the clinician works around the canal walls. Some people find the sound of the suction device (a gentle "whirring") a little odd. Deep, firm wax closer to the eardrum may require more careful work and can sometimes cause a brief, mild sensation.
Preparation: Most clinicians recommend using olive oil or sodium bicarbonate ear drops for 3–5 days before the appointment to soften the wax, making it easier and quicker to remove. However, even without pre-treatment, experienced clinicians can usually manage most wax.
After the procedure: You may feel an immediate improvement in hearing. Some people report the ear feeling slightly "open" or "echoey" for a few hours — this is normal and subsides as you adjust.
Key Benefits of Microsuction
- Dry procedure — no water involved, eliminating the risk of swimmer's ear or middle ear infections from moisture
- Direct visualisation — the clinician sees everything they're doing, greatly reducing the risk of eardrum damage
- Suitable for almost everyone — including those with perforated eardrums, mastoid cavities, grommets (ventilation tubes), and previous ear surgery (where irrigation is contraindicated)
- Immediate results — you can hear the improvement before you even sit up
- Fast — typically 5–15 minutes per ear
- No recovery time — you can drive, fly, and resume normal activities immediately
- Can be used diagnostically — the microscope also allows the clinician to examine the eardrum for any pathology at the same time
Risks and Side Effects
Microsuction is very safe when performed by an experienced clinician. However, no medical procedure is risk-free. Potential side effects include:
- Mild dizziness — brief, common, especially if wax is close to the eardrum; usually resolves within minutes
- Minor canal irritation — the canal skin is delicate and can be briefly reddened or scraped; heals quickly
- Temporary hearing change — the ear can feel "full" or muffled for a few hours post-procedure as any residual oil/drops settle
- Tinnitus — very occasionally, patients report temporary ringing immediately after; usually resolves
Serious complications (eardrum perforation, significant hearing loss, infection) are extremely rare in experienced hands.
Who Should (and Shouldn't) Use It?
Microsuction is particularly suitable for:
- People with perforated eardrums (irrigation is contraindicated; microsuction is safe)
- Those with grommets (ventilation tubes)
- Patients who have had mastoid surgery or other ear operations
- People with narrow or tortuous ear canals
- Those who've previously had complications from irrigation
- Anyone who wants the safest, most precise option available
Cost and Availability
In Australia and the UK, microsuction is commonly available through ENT specialist rooms and independent audiology clinics. Costs typically range from AUD $80–$180 per appointment (both ears), depending on the provider and location. In the US, ENT-audiology combo clinics offer it for approximately $75–$200.
GPs may offer ear irrigation (water flush) under Medicare/Bulk Bill (Australia) or NHS (UK) at little to no cost, but microsuction — being a specialist procedure — often attracts a private fee.
