Is microsuction safe? Risks and side effects explained
Microsuction is widely used and generally very safe. The side effects people notice, the rare risks with figures from ENT UK, and who should take extra care.
In short
- Microsuction is a very safe way to remove ear wax when a trained clinician does it and can see into your ear throughout.
- The side effects people notice are noise, brief dizziness, a tickly cough and mild soreness. They pass quickly.
- Serious complications are rare. ENT UK estimates damage to the eardrum at less than 1 in 10,000 procedures.
- Before you start, tell the clinician about past perforations, ear surgery, grommets, blood thinners and any sensitivity to noise.
- Contact the clinic, your GP or NHS 111 if you have severe pain, discharge, bleeding that won't stop or new hearing loss afterwards.
Yes. Microsuction is considered a very safe way to remove ear wax. The clinician can see into your ear the whole time, nothing wet goes in, and the side effects people notice, such as noise, brief dizziness and a little soreness, usually pass within minutes. Serious problems like a damaged eardrum or an infection are rare. What keeps it safe is who does it, and whether they know your ear history before they start.
Why microsuction is considered safe
The main reason is that the clinician can see what they are doing. They work through a microscope, magnifying loupes or an endoscope, so the wax, the wall of the canal and the eardrum are in view as they go. If something looks wrong they can stop, change angle or switch to a small instrument. With the old metal ear syringe, nobody could see inside the ear while the water was going in.
Being dry is the other advantage. Microsuction can be used on ears that shouldn't get wet, which is why hospital ENT clinics use it for people who have had a perforated eardrum or ear surgery, where irrigation is usually avoided. NICE guidance lists microsuction alongside electronic irrigation as a method trained practitioners in GP and community services can use.
Common side effects
These are the things people most often notice during or just after microsuction. They are expected, and they aren't signs that anything has gone wrong.
Usually over within minutes
- Noise. The suction is loud, and a piece of wax in the tube can make a high-pitched squeal.
- Brief dizziness, more likely if you have had mastoid surgery or feel anxious.
- A tickly cough, because touching the skin of the canal can set off a cough reflex.
- Discomfort, mainly when wax is stuck deep in the ear or the canal is already sore.
- A stiff neck from holding your head tilted to one side.
- Sounds seeming loud for a while once a long-standing blockage has gone.
Fainting is very rare. If you tend to faint, tell the clinician: ENT UK suggests lying down for the procedure. Neck or back pain is worth mentioning too, so you can be positioned comfortably.
Rare risks and complications
ENT UK, the professional body for ear, nose and throat specialists in the UK, publishes estimates of how often complications happen with microsuction. They give a helpful sense of scale.
| Complication | ENT UK estimate |
|---|---|
| Minor scrape to the ear canal, with brief pain or bleeding | About 5 in 100 |
| Temporary tinnitus (ringing in the ear) | About 1 in 100 |
| Vertigo (a spinning feeling) | About 1 in 200 |
| Outer ear infection after a scrape | About 1 in 500 |
| Temporary conductive hearing loss | About 1 in 1,000 |
| Permanent tinnitus | About 1 in 5,000 |
| Damage to the eardrum | Less than 1 in 10,000 |
| Permanent nerve-related hearing loss | Less than 1 in 10,000 |
Put simply, the only thing that happens with any regularity is a small scrape to the skin of the canal. It may sting and bleed a little, and ENT UK says both usually settle within seconds or minutes once the suction stops. Everything else on the list is uncommon, and the serious outcomes are very rare. When an eardrum is damaged, it usually heals within a few weeks, though occasionally the hole is permanent.
Noise is the worry people raise most often. The suction is loud when the tube is close to the eardrum, and ENT UK notes that people who are sensitive to noise are more likely to notice tinnitus afterwards, usually for a short time only. If you already have tinnitus or find loud sounds hard to bear, say so beforehand: the clinician can use other instruments, although it may take longer. Our guide to ear wax and tinnitus covers ringing that comes with a blockage.
Who should take extra care
Microsuction suits most people, but some situations need a little more thought. Tell the clinician if any of these apply to you.
- A perforated eardrum, grommets or ear surgery, now or in the past. Microsuction is often the preferred method, but the clinician needs to know what they are looking at.
- Blood-thinning medicines such as warfarin, apixaban or aspirin, as a small scrape may bleed for longer.
- Diabetes or a weakened immune system, which can make an ear canal infection harder to shake off.
- A current ear infection. A painful, swollen or discharging ear may need treatment first.
- Tinnitus or sensitivity to noise, so the clinician can keep suction to a minimum.
- Difficulty keeping still, for example because of a tremor or dementia. Sudden movements make scrapes more likely.
None of these usually rules microsuction out. They may change how it is done, or mean you are better seen in a hospital ENT clinic. Children can have microsuction too, although some clinics only treat adults; our guide to ear wax in children explains when removal is needed at all.
Do
- tell the clinician about your ear history and any medicines you take
- use softening drops beforehand if the clinic asks you to
- raise a hand straight away if it hurts or you feel dizzy
- sit for a few minutes afterwards if you feel light-headed
Don't
- try to dig wax out yourself beforehand with cotton buds, hairgrips or camera ear picks
- keep quiet about pain during the procedure
- put anything in your ear afterwards if it feels sore
- ignore pain, discharge or new hearing loss in the days that follow
Who should carry it out
Microsuction is done by a range of professionals, including nurses, audiologists, hearing aid audiologists and ENT doctors. NICE's guidance is that whoever removes ear wax should have training and expertise in the method, know the situations in which it shouldn't be used, and have the right equipment.
In practice, that means it is perfectly reasonable to ask a clinic who will treat you, what their background is and what training they have had in wax removal. A good clinic will be happy to tell you. Our guide on choosing an ear wax removal clinic lists the questions worth asking, and microsuction vs irrigation explains when each method is the better fit.

After microsuction: what's normal and what isn't
Most people leave with nothing more than clearer hearing. A slightly tender canal for a day or so, sounds seeming louder than usual and a little itchiness as the skin settles are all normal. ENT UK says you don't usually need painkillers afterwards, although paracetamol is fine if the procedure was uncomfortable, and you don't have to keep your ear dry unless your clinician tells you to. Our aftercare guide explains how to look after your ears over the next few days.
If you have a problem afterwards, ENT UK advises contacting the clinic that treated you first. Some symptoms need a doctor, though.
Get help from your GP or NHS 111 if, after microsuction, you have
- severe or worsening ear pain
- bleeding that doesn't stop, or discharge from the ear
- a high temperature, or redness and swelling around the ear
- sudden hearing loss, or hearing that is getting worse
- spinning dizziness that doesn't settle
Don't wait to see whether sudden hearing loss clears by itself. It needs to be seen quickly.
Common questions
Can microsuction damage your hearing?
It is very unlikely. ENT UK puts permanent nerve-related hearing loss from microsuction at less than 1 in 10,000 cases. Temporary muffling is a little more common, for example if a scrape bleeds and leaves some blood in the canal, and it usually clears. For most people, hearing is better after microsuction than before.
Is it safe to have microsuction regularly?
There is no set limit. Some people, such as hearing aid users, have wax removed every few months. Each session carries the same small risks, so it is worth asking the clinician whether regular drops could stretch the gap. Our guide to how often ear wax should be removed covers sensible routines.
Can I have microsuction with a perforated eardrum?
Often, yes. Because nothing wet goes into the ear, microsuction is usually preferred over irrigation when the eardrum is, or has been, perforated. Tell the clinician beforehand, as some ears are better cleaned in a hospital ENT clinic. Don't use drops in an ear that might be perforated unless a doctor has told you to.
What happens if the clinician can't remove all the wax?
They will usually stop rather than force it. Hard wax stuck to the canal wall can be uncomfortable to remove in one go, so you may be asked to use softening drops for a few days and come back. ENT UK notes that some people need more than one session, and it isn't a sign that anything has gone wrong.
