Micro-suction vs ear syringing: what is the difference and which is safer?

What is the difference between micro-suction and ear syringing?

If earwax has built up and drops have not shifted it, the HSE says a GP may flush the wax out with water, known as ear irrigation, or suck it out, known as microsuction. Many people still call the water method ear syringing. This guide to microsuction vs ear syringing explains how each one works and what the guidance says about risk.

Traditional ear syringing used a hand-held syringe filled with water. Modern irrigation uses an electronic machine that pumps water into the ear at a controlled pressure, and the British Society of Audiology (BSA) points out that manual syringing and irrigation are not the same process.

Micro-suction uses a fine suction tube to lift wax out while the ear canal is viewed through a microscope, magnifying loupes or an endoscope. Because it is done under direct vision and no water goes into the ear, it can be used in some situations where irrigation would not be suitable.

Microsuction vs ear syringing at a glance

Which carries less risk?

It depends on your ears and your health. The BSA notes that the evidence behind current methods is of low or very low quality, and that NICE found no robust health economic evidence favouring one technique over another.

Manual syringing has fallen out of favour. The BSA, quoting NICE guidance from 2018, says it should not be offered, and a 2023 British Journal of General Practice editorial says manual water-filled syringes are no longer recommended in the UK. An NHS Humber and North Yorkshire policy says electronic irrigation, which controls water pressure, carries less risk, and that microsuction is not without risks either.

A 2020 paper in BJGP Open estimated that complications occur in about one in 1,000 ears irrigated, and put the risk of an outer ear infection after irrigation at around three in 100. The BSA says irrigation can cause harm where the eardrum is not intact, and lists these reasons not to irrigate:

• a current or past perforated eardrum
• previous ear surgery
• grommets still in place
• a cleft palate, even if repaired

There is also a small risk of a serious outer ear infection called necrotising (malignant) otitis externa after wax removal. The BJGP Open paper says it is more common after irrigation, particularly in people with diabetes or a weakened immune system, and notes it has been suggested that irrigation be avoided in older, diabetic and immunocompromised patients.

Micro-suction has its own downsides, although ENT UK says most ENT doctors prefer it to irrigation or manual clearance and that it should be regarded as the method of choice for wax removal. The BJGP Open paper reports a 91% clearance rate, but in one study of 164 ENT outpatients, 55% reported side effects, mostly minor and short lived. ENT UK estimates that injury to the ear canal skin, with more pain than expected or some bleeding, happens in about one in 20 cases and usually settles within minutes once suction stops.

Some problems rule out every method for now. The BSA lists active otitis externa, eczema or psoriasis, and cuts, bruising, inflammation or infection of the ear canal skin, and its checklist applies this to suction as well as irrigation. If you hear in only one ear, it advises against irrigating that ear, and its checklist advises manual removal only, not suction.

What micro-suction feels like

ENT UK says micro-suction can be uncomfortable if wax is packed deep in the ear canal. It can take anything from a few seconds to 20 minutes, seated or lying down.

• It is noisy. The BSA says sound levels in the ear during suction can exceed 85 dB A in some cases, and that this can make existing tinnitus worse. ENT UK notes some reports of up to 140 decibels.
• Dizziness is common. ENT UK says the suction of air from the ear canal often causes some dizziness.
• Coughing can happen. ENT UK says this is through the vagus nerve, and fainting is very rare.

If you are sensitive to sound, say so. ENT UK says a smaller suction tip reduces the noise, although removal takes longer, and if the procedure becomes painful it advises stopping, using softening drops and coming back another day.

Getting your ears ready

The HSE suggests softening earwax at home first with olive or almond oil:

• Put two to three drops into the affected ear.
• Lie on your side for five to 10 minutes.
• Repeat three to four times a day for three to five days.

Lumps of wax may fall out over about two weeks. Do not use drops if you have a hole in your eardrum. A bottle of Ultrapure olive oil ear drops 100ml costs €5.95.

ENT UK says drops are not usually necessary before micro-suction when it is done by an experienced practitioner, but five days of drops may make clearance easier, and no one softener is better than another. A 2018 Cochrane review likewise found no evidence that oil drops worked better or worse than plain water or saline.

The HSE says there is no evidence that ear candles or ear vacuums get rid of earwax, and advises against using fingers or cotton buds, which push wax further in and make it worse.

When to see your GP

The HSE advises seeing a GP if earwax has not cleared after five days of drops. Pharmacy micro-suction is another option if you are 16 or over, but speak to your GP first if:

• your ear is painful, swollen, irritated or has a discharge
• you have, or think you may have, a hole in your eardrum
• you hear in only one ear
• the person needing treatment is under 16

Before any wax removal, tell the pharmacist if you have diabetes or a weakened immune system, or have had ear surgery, grommets or a perforated eardrum, so they can check whether micro-suction suits you.
