What Is Microsuction Ear Wax Removal?
How microsuction works, what happens during an appointment, who it is suitable for and why it has become the gold standard in UK ear care.
Microsuction is the method most consistently recommended by UK audiologists and ENT specialists for safe, effective ear wax removal. It is a dry procedure — no water is used at any point — in which a trained clinician uses a fine, low-pressure suction probe to lift wax from the ear canal under direct magnified visualisation. Because the clinician can see exactly what they are doing throughout, microsuction is significantly safer and more precise than water-based irrigation.
Approximately 2.3 million people in the UK require professional ear wax treatment each year. Microsuction is the primary private-sector method and is also offered by some NHS GP practices and hospital audiology departments. Most appointments take 15 to 30 minutes and resolve the blockage in a single session.
Why Microsuction Is the Gold Standard
- No water used — suitable for perforated eardrums and post-surgery ears
- Direct magnified view throughout — clinician sees the canal and drum at all times
- Resolves most impactions in a single 15 to 30 minute appointment
- Recommended by NICE guidelines for ear wax impaction
- Suitable for hearing aid wearers, grommets and sensitive ears
- Success rate exceeds 95% across all wax presentations
- No pre-procedure water exposure risk to the canal

How Microsuction Works: The Procedure in Detail
Understanding exactly what happens during a microsuction appointment removes any anxiety around the procedure and helps you prepare correctly.
01
Assessment
The clinician reviews your ear history — previous surgery, perforations, infections, grommets — and examines both ear canals with an otoscope. This confirms wax is present, assesses its consistency and identifies any reasons the procedure should not proceed.
02
Visualisation
A binocular microscope, head loupe or digital endoscope is positioned to give the clinician a magnified, well-lit view of the ear canal. This direct vision is maintained throughout the entire procedure — distinguishing microsuction from all irrigation-based methods.
03
Suction Removal
A fine suction probe (typically 1.5 to 2.5mm in diameter) connected to a low-pressure suction unit is gently inserted into the canal. The clinician carefully lifts and removes wax under continuous visual guidance. The suction unit produces a notable noise — this is normal and expected.
What to Expect: Before, During and After
Before the Appointment
Use olive oil drops or spray twice daily for five to seven days before your appointment. Pre-softening is the single most important thing you can do to improve the success rate. Do not use hydrogen peroxide or carbamide peroxide drops — these can make wax stickier and impede suction. One in four microsuction appointments is unsuccessful at the first attempt when no pre-softening has been done.
During the Procedure
You will hear a loud suction noise throughout — this is normal. You may feel mild pressure and occasional brief discomfort if the probe contacts the canal wall, but microsuction should not be painful. If you feel sharp pain at any point, tell the clinician immediately. The procedure is typically 15 to 30 minutes for both ears.
After the Appointment
Most patients notice immediate improvement in hearing. Some experience temporary mild tinnitus or a feeling of heightened sound sensitivity for a few hours — this settles. In rare cases, mild dizziness occurs and resolves quickly. If hearing does not improve, or if pain or discharge develops within 48 hours, contact the clinic or your GP.
Microsuction vs Irrigation: Patient Outcome Comparison
Microsuction outcomes consistently outperform irrigation across safety, clearance rate and suitability for patients with complex ear histories. Figures from UK audiology clinical audit data.
Who Is Microsuction Suitable For?
| Patient Group | Suitable for Microsuction? | Notes |
|---|---|---|
| Healthy adults with routine wax build-up | Yes | First-line professional treatment |
| Hearing aid wearers | Yes | Particularly beneficial — wax interferes with hearing aid function |
| Perforated eardrum (healed) | Yes | Dry procedure — no water risk to middle ear |
| Active perforation | With caution | Clinician assessment required — often still possible |
| Grommets in place | Yes | Water-based irrigation contraindicated; microsuction preferred |
| History of ear surgery | Yes | Clinician should be informed — generally safe |
| Active outer ear infection | Not usually | Infection should be treated before wax removal where possible |
| Severe tinnitus sensitivity | With caution | Suction noise can temporarily aggravate tinnitus — discuss with clinician |
| Children under 12 | Specialist referral | Typically referred to ENT paediatric services |
Is microsuction available on the NHS? Ear wax removal is not part of the standard NHS GP contract in England, meaning many surgeries do not offer it. Where it is available, there may be waiting times. Private microsuction appointments are widely available across the UK, typically costing between £50 and £80 for one or both ears, with appointments often available within days.
