Wax is supposed to be there
Start from the fact that surprises most people: earwax is not dirt, and a clean ear canal is not the goal.
Cerumen — the medical name for earwax — is produced by specialised glands in the outer third of the ear canal and mixed with shed skin cells and the oily secretion of nearby sebaceous glands. It is slightly acidic, which discourages bacterial and fungal growth. It is water-repellent, which keeps the canal skin from becoming waterlogged in a climate like ours. It traps dust, insects and debris before they reach the eardrum. And it lubricates skin that has no other moisturising mechanism, which is why over-cleaned ear canals become dry, itchy and cracked.
The canal also cleans itself, by a genuinely elegant mechanism. The skin lining the ear canal migrates outward, like a very slow conveyor belt, carrying wax and debris with it from the eardrum toward the opening, where jaw movement from chewing and talking helps work it out. This process runs continuously without any intervention from you. In the great majority of people, ears require exactly nothing.
How much wax you make, and what consistency it is, is largely genetic. Some people produce dry, flaky wax; others produce wet, sticky wax. Neither is abnormal or a sign of poor hygiene. Production tends to slow with age while the wax itself becomes drier and harder, which is part of why impaction is more common in older adults. Narrow or unusually angled canals, a lot of hair in the canal, and skin conditions like eczema all make wax more likely to accumulate.
So the honest position is this: most ears need no cleaning, most wax needs no removal, and a substantial part of a doctor's job in this area is persuading people to stop doing things to their ears. Wax becomes a problem only when it accumulates enough to block the canal, when it presses on the eardrum, or when it prevents examination of an ear that needs to be examined. That does happen, it is uncomfortable, and it is easily treated — but it is the exception, not the routine state of a healthy ear.
Klinik Muhibbah in Masai sees this constantly, from all over Masai, Kota Masai, Taman Rinting, Bandar Seri Alam and Pasir Gudang. Much of the time the useful intervention is a look, an explanation, and no procedure at all.
Stop using cotton buds. This is the most useful sentence on this page.
If you take one thing from this page, take this: cotton buds do not clean your ears. They pack wax inward.
The mechanics are simple and unforgiving. The ear canal is roughly the diameter of a pencil and a bud is roughly the diameter of a pencil. When you insert it, the tip acts as a plunger. A small amount of wax clings to the cotton and comes out — which is exactly why the technique feels effective, because you can see it on the bud — while the bulk of the wax is pushed deeper, past the outward-migrating skin that was already moving it out, and compacted against the eardrum where the canal is narrower and where nothing can shift it. Repeat that daily for years and you build a dense plug in the deepest, least accessible part of the canal, in a place where wax is not even produced.
A large proportion of the impacted wax we remove was put there by the patient. That is not a criticism; almost everybody was taught to do this. But the causation runs the opposite way to what people believe: buds are not the treatment for wax build-up, they are the leading cause of it.
The second harm is worse and less common. The eardrum is a thin membrane a very short distance in. A bud pushed too far, or a bud in the ear when someone bumps your elbow, a child runs into you, or you are jolted, can perforate it. Perforation causes sudden sharp pain, sometimes bleeding, hearing loss, and a risk of infection entering the middle ear. It can also damage the tiny bones behind the drum. Emergency departments see these injuries regularly, and a disproportionate number of them are in children.
The third harm is chronic. Repeated trauma to the canal skin strips its protective lipid layer, causing itch. The itch prompts more cleaning. More cleaning causes more itch and eventually breaks in the skin, which is how bacterial otitis externa gets started. It is a self-sustaining cycle and the only way out is to stop.
The same applies to hairpins, keys, matchsticks, pen caps, folded tissue, fingernails, and the metal ear picks sold in some shops. Nothing smaller than your elbow, as the old advice goes, and it is correct.
If your ears feel blocked or itchy, that is a reason to be examined, not a reason to dig. Come in and let someone actually look.
Ear candling does not work, and it burns people
Ear candling — sometimes called ear coning — involves inserting a hollow fabric cone soaked in wax into the ear canal and lighting the far end, on the theory that the flame creates suction that draws wax and toxins out of the ear.
It does not. This has been studied and the mechanism does not exist: measurement shows no negative pressure generated in the canal, and wax quantities in the ear are unchanged after treatment. The brown residue found inside the cone afterwards — the thing presented as proof — is the candle's own melted wax and burnt fabric, and it appears identically when a candle is burned without any ear present at all.
The harms are real and documented: burns to the face, the outer ear and the canal from dripping molten wax, deposits of candle wax left inside the canal that then have to be removed, perforated eardrums, and occlusion of a canal that was previously clear. There are also cases of hair catching fire.
Alongside that sits the more ordinary cost — delay. Someone whose blocked ear is actually otitis externa, a middle ear effusion, or sudden sensorineural hearing loss spends two weeks on candling instead of being examined. In the last of those, that delay can cost permanent hearing.
The same scepticism should be applied to ear vacuum devices sold online, to at-home irrigation kits used without knowing whether your eardrum is intact, and to "ear cleaning" services offered by people with no clinical training and no otoscope. The common thread in all of them is that nobody has looked inside the ear before doing something to it, which is the one step that actually matters.
Softening drops, used sensibly, are a legitimate home measure and are covered in the next section. Beyond that, the useful home treatment for earwax is leaving it alone.
When wax genuinely needs removing, and how it is done
Removal is appropriate when wax is causing a problem, not when it merely exists.
The genuine indications are: hearing loss or a blocked, muffled sensation attributable to wax; a feeling of fullness or pressure; earache caused by a plug pressing on the canal wall or eardrum; tinnitus or dizziness that resolves once the wax is cleared; wax preventing a hearing aid from seating properly or causing it to whistle; and wax obstructing the view of an eardrum that needs to be examined — a very common reason in practice, since a doctor cannot assess an ear they cannot see. Occupational audiometry is another: a canal full of wax will produce a falsely poor hearing test result and muddy the surveillance record.
Softening drops come first in most cases. Olive oil, or a pharmacy wax-softening preparation, instilled into the ear for several days, will often break up a plug enough that it comes out on its own. Lie on your side with the affected ear uppermost, put in the drops, stay there for several minutes so they reach the plug rather than running straight out, and repeat as directed. Softening also makes any subsequent procedure faster, gentler and more likely to succeed at the first attempt, which is why we frequently advise a few days of drops rather than attempting removal on a rock-hard plug the same afternoon.
Irrigation is the method most people mean by "syringing". Water at body temperature is directed along the wall of the canal so that it flows behind the plug and floats it out. Done properly it is painless and takes minutes, and the relief when a plug releases is immediate and slightly startling. Water that is too cold or too hot causes dizziness and nausea by stimulating the balance organ, which is why temperature matters. This is the method we most commonly use at the clinic, and it is why we may ask you to use drops for a couple of days first.
Microsuction uses a fine suction device under direct vision through a microscope or loupes. Its advantage is that no water enters the ear, which makes it the preferred method for people who cannot safely be irrigated — the group described in the next section — and it can be done on a hard plug without softening. It is louder for the patient and requires specific equipment. Where microsuction is the appropriate method for your ear, we will tell you and arrange the referral rather than irrigating anyway.
Manual removal with instruments under direct vision is used for wax sitting near the opening or for foreign bodies.
Whichever method, the ear is examined before and after. Removing wax without looking first is how avoidable harm happens.
When the ear must not be irrigated
Irrigation is safe in the right ear and unsafe in the wrong one, and the difference is not something you can judge from outside. This is the main reason to have wax removed by someone with an otoscope rather than at home with a bulb syringe bought online.
Do not irrigate, and tell the doctor before anything is done to your ear, if any of the following apply.
A known or suspected perforated eardrum. Forcing water through a hole in the drum drives it into the middle ear, which can cause infection, severe pain and dizziness. If you have ever had a discharging ear, an eardrum described as perforated, or an injury to the ear, say so.
Grommets — ventilation tubes placed through the eardrum, usually in children with recurrent middle ear fluid. A grommet is a deliberate hole. The same objection applies.
Previous ear surgery of any kind: mastoid surgery, tympanoplasty, ossicular reconstruction, or anything else. Post-surgical anatomy can be unpredictable and a cavity may communicate with structures that must stay dry.
Active infection or a discharging ear. Irrigating an infected canal is painful and pushes infected material deeper.
An only-hearing ear, or a substantial pre-existing hearing loss in the ear concerned. The risk of any complication is the same, but the consequence is not, so the threshold is higher.
A history of significant dizziness or vertigo, since irrigation can provoke it.
A foreign body rather than wax — particularly organic material such as a seed or a bean, which swells when wet and becomes far harder to remove, or a button battery, which is a genuine emergency because it causes chemical burns within hours and must be removed the same day.
For all of these, microsuction or manual removal under vision is the appropriate route, and that is what we will arrange.
Two further points. Children's ears are not simply smaller: the canal is shorter and narrower, the drum is closer, and cooperation is limited, so we are conservative. Wax rarely needs removing in a child at all unless it is preventing examination or affecting hearing. And if you experience severe pain, sudden dizziness, or discharge during or after any ear procedure, stop and tell someone immediately rather than pushing through it.
It is often not wax at all: otitis externa in a humid climate
A blocked, uncomfortable ear is very frequently not a wax problem, and the most common alternative in this part of the world is otitis externa — infection or inflammation of the ear canal skin, known colloquially as swimmer's ear.
Malaysia's climate is close to ideal for it. Persistent high humidity keeps the canal skin damp. Swimming and frequent showering add water. Sweat during outdoor and industrial work adds more. Earphones and industrial hearing protection worn for long shifts occlude the canal, raising temperature and humidity further and trapping moisture against the skin. And the cotton bud habit described earlier strips the protective wax layer and creates the micro-abrasions through which bacteria enter. Put those together and you have why this diagnosis is so common here compared with temperate countries.
The symptoms are distinguishable from wax if you know what to look for. Otitis externa itches first, then becomes genuinely painful — and characteristically the pain is much worse when the outer ear is pulled or when the small cartilage flap at the front of the canal is pressed, a sign that does not occur with a wax plug. The canal may swell shut, producing hearing loss that mimics wax exactly. There may be discharge, sometimes watery, sometimes thick, occasionally with an odour. The ear may feel hot. Wax impaction, by contrast, causes fullness and muffled hearing, sometimes mild ache, but is not typically tender to touch and does not discharge.
Fungal infection of the canal — otomycosis — is also common in humid conditions and after prolonged antibiotic drops. It tends to itch more than it hurts, and on examination shows a distinctive appearance that a doctor can recognise and that you cannot see yourself.
Treatment is different in each case, which is why the distinction matters. Otitis externa is treated with topical drops appropriate to the organism, careful cleaning of the canal, pain relief, and keeping the ear dry — which means no swimming, and drying the ear gently after showering rather than inserting anything to absorb water. Fungal infection needs antifungal treatment; giving it antibacterial drops makes it worse. Neither responds to wax softening drops, and irrigating either one is painful and counterproductive.
Diabetes matters here. In a person with poorly controlled diabetes, or someone immunosuppressed, an outer ear infection can rarely progress to a severe infection of the skull base — necrotising otitis externa — which is a serious condition requiring hospital treatment. Persistent, severe ear pain in a diabetic patient, especially with discharge and pain out of proportion to the appearance, needs proper assessment and not another course of drops. We have blood tests on site and can check your diabetes control the same visit.
Middle ear infection, fluid, and the ear that keeps blocking
Behind the eardrum is the middle ear, an air-filled space connected to the back of the nose by the Eustachian tube. Problems here produce blocked-ear sensations that patients reasonably assume are wax.
Acute otitis media is infection of that space, and it is far more common in children because their Eustachian tube is shorter, narrower and more horizontal. It typically follows a cold, produces rapid-onset ear pain, fever, and a miserable child, and sometimes ends abruptly with discharge when the drum perforates and the pressure releases — which, counterintuitively, usually relieves the pain, and the perforation usually heals. Most cases in otherwise well children settle with pain relief and observation; antibiotics are used selectively, in younger children, in severe or bilateral cases, and where there is discharge or the child is systemically unwell.
Otitis media with effusion — glue ear — is fluid sitting in the middle ear without acute infection, most often after a cold or a run of infections. It causes hearing loss without pain, and in a child that shows up as turning the television up, not responding when called, seeming inattentive, or falling behind at school. It is easy to mistake for a behaviour problem. Most cases resolve over weeks to a few months; persistent cases affecting hearing and development are referred, and grommets are one of the treatments considered.
In adults, Eustachian tube dysfunction produces a blocked, popping, pressure sensation, often worse with a cold, on a flight, or with allergic rhinitis, which is extremely common in Malaysia given year-round dust mite and pollen exposure. Treating the nose frequently treats the ear.
One adult presentation must never be brushed off. Persistent one-sided middle ear fluid in an adult, with no obvious cause and not resolving, warrants examination of the nasopharynx — because nasopharyngeal carcinoma is significantly more common in Southeast Asian populations, particularly in Chinese Malaysians, and unilateral hearing loss with middle ear fluid is one of its classic early presentations. Other warning features are a lump in the neck, blood-stained nasal discharge or persistent one-sided nasal blockage. This is not a reason to panic about a blocked ear during a cold. It is a reason not to accept a one-sided blocked ear that has lasted months without anyone looking properly, and a reason we refer that specific picture rather than watching it.
Sudden hearing loss is an emergency. Do not wait for it to clear.
This section is here because the most damaging mistake made about ears is assuming that sudden hearing loss is wax.
Sudden sensorineural hearing loss is a rapid loss of hearing in one ear — typically over minutes to hours, and by definition within three days — caused by a problem in the inner ear or the hearing nerve rather than a blockage of the canal. It commonly happens overnight: the person wakes up and one ear simply is not working. It may be accompanied by tinnitus, a feeling of fullness, or dizziness.
It is treated as a medical emergency because the treatment window is short. Corticosteroid treatment, given orally or by injection through the eardrum, gives the best chance of recovery when started early — ideally within days, with results falling away substantially after about two weeks. Hearing not recovered in that window is often not recovered at all. This is one of the few genuinely time-critical conditions in ENT.
The problem is that it does not feel like an emergency. It is painless. There is no fever. Patients very reasonably assume it is wax, or fluid from a cold, try drops for a week, and then attend when the window has closed.
So: if you lose hearing suddenly in one ear, and particularly if it is painless, seek medical assessment the same day. Not next week. A doctor can look in the ear and establish immediately whether there is a wax plug or an obvious infection — which are reassuring findings — and if the canal and drum look normal, you need urgent ENT referral for formal hearing testing and treatment. We will arrange that referral urgently rather than trying to manage it here.
The same urgency applies to sudden hearing loss with severe vertigo and vomiting, to hearing loss after a head injury or a blast or explosion, to sudden hearing loss with facial weakness, and to an ear injury that causes immediate pain, bleeding and deafness.
Klinik Muhibbah is open Monday to Thursday and Saturday until 9PM, Friday to 3PM and Sunday to 1PM. If sudden hearing loss occurs outside those hours, go to a hospital emergency department rather than waiting for us to open. For anything with severe pain, high fever, facial weakness, severe dizziness with vomiting, or a swollen tender area behind the ear — which can indicate mastoiditis — go to an emergency department or call 999.
Tinnitus: what it is, what it is not, and what actually helps
Tinnitus is the perception of sound with no external source — ringing, hissing, buzzing, whistling, roaring or clicking. It is extremely common, it is a symptom rather than a disease, and the level of distress it causes correlates poorly with how loud it actually is.
Wax impaction is a genuine and satisfying cause, because clearing the plug removes the tinnitus entirely. That is a real proportion of cases and it is one reason an examination is worth doing before assuming the worst.
Beyond that, the common associations are noise exposure and age-related hearing loss — tinnitus and hearing loss travel together far more often than people realise, and many people with tinnitus have a hearing loss they had not noticed. Middle ear fluid, Eustachian tube dysfunction, certain medications, high blood pressure, anaemia and thyroid disorders can all contribute, and we can test for several of those from a blood sample on site.
Some patterns need proper assessment rather than reassurance. Tinnitus in one ear only, tinnitus with asymmetric hearing loss, pulsatile tinnitus that beats in time with your heartbeat, and tinnitus with neurological symptoms all warrant investigation and referral rather than being accepted as ordinary.
For the ordinary kind, the honest position is that there is often no medication that abolishes it, and pretending otherwise wastes people's money. What genuinely helps is more prosaic. Treating any underlying cause, including wax and hearing loss — hearing aids frequently reduce tinnitus substantially by restoring the ambient sound the brain is missing. Sound enrichment, so the tinnitus is not competing against silence, particularly at night. Protecting hearing from further noise. Addressing sleep, because exhaustion amplifies it. And addressing anxiety, because the relationship runs both ways: tinnitus generates anxiety, and anxiety makes tinnitus intrusive, and breaking that loop is the single most effective intervention for most sufferers.
Tinnitus that is driving someone to despair is not a minor complaint and should be treated seriously. If it has reached the point of hopelessness, say so — Befrienders KL provides confidential emotional support on 03-7627 2929, and it is a reasonable thing to raise with your doctor.

Industrial hearing loss, audiometry, and the Pasir Gudang workforce
Klinik Muhibbah sits a few minutes from one of the densest industrial areas in southern Johor — the Pasir Gudang and Tanjung Langsat belt, MMHE, the fabrication yards, the petrochemical and oleochemical plants, the port and the logistics operations. Noise-induced hearing loss is the most commonly notified occupational disease in Malaysia, and a large proportion of the people reading this page work in exactly the environments that cause it.
Noise damages hearing by destroying hair cells in the cochlea. Those cells do not regenerate. There is no medication, no surgery and no procedure that restores them. Every gain has to come from preventing the damage in the first place, which is why detection matters so much and why it has to happen before the worker notices anything.
That is the crucial and counterintuitive part. Noise-induced hearing loss begins at frequencies above those most important for conversation, so for years a worker hears speech normally and believes their hearing is fine. What they notice first, if anything, is difficulty following conversation in a noisy restaurant or a crowded room, and temporary ringing or muffled hearing after a shift — which recovers overnight and is therefore dismissed. That temporary shift is the warning. It is the cochlea telling you it was overloaded, and repeated often enough it becomes permanent.
Audiometry catches it earlier than the worker can. A formal hearing test presents tones across a range of frequencies and maps the quietest level you can detect at each. Noise damage produces a characteristic notch in the higher frequencies, and comparing this year's audiogram against a baseline reveals a significant threshold shift while it is still preventable through better protection and engineering controls. An audiometry programme where nobody compares this year to last year is paperwork, not hearing conservation.
Wax matters here too, and it is a practical point employers should know: a canal blocked with wax produces a falsely poor audiogram, wasting the test and corrupting the surveillance record. Ears are checked before testing for that reason, and where wax is found it should be cleared and the test repeated.
Dr. Prabagaran Kanapathy (M.D UNPAD, MMC 63651) is a NIOSH-certified Occupational Health Doctor, which is the certification required for statutory medical surveillance under the framework administered by DOSH — audiometry for noise-exposed workers, spirometry for those with respiratory exposure, and the fitness determinations employers actually need. Our occupational health and audiometry pages set out what a surveillance programme involves, and employers arranging groups should call ahead on +60 7-251 1162 rather than sending workers unannounced.
For individual workers: hearing protection only works when it is worn continuously. Removing earmuffs for ten minutes in an eight-hour shift disproportionately reduces the protection you received, because noise exposure is cumulative and logarithmic. And if your ears ring after work, that is not normal and it is worth saying out loud.
Coming in for your ears
Klinik Muhibbah is at No. 62 Jalan Kiambang, Taman Bunga Raya, 81700 Masai, Johor — convenient for Masai, Kota Masai, Taman Rinting, Bandar Seri Alam, Taman Scientex, Pasir Gudang and the surrounding townships.
We are open Monday to Thursday and Saturday 9AM to 9PM, Friday 9AM to 3PM, and Sunday 9AM to 1PM. Walk in during those hours; no appointment is needed. Calling +60 7-251 1162 or messaging +60 17-500 7205 first can shorten your wait, and you can book at movo-x.com/kiosk/muhibbah.
Two things make a wax removal visit go well. First, if the blockage has been building for a while and you are not in pain, using olive oil or softening drops for two or three days beforehand makes the procedure quicker, gentler and much more likely to work at the first attempt. It is not essential — come in anyway if you are uncomfortable — but it helps. Second, tell the doctor before anything is done if you have ever had a perforated eardrum, grommets, ear surgery, a discharging ear, significant hearing loss in one ear, or bad dizziness. Those change which method is safe, and the section above explains why.
Do not attempt to clear a blocked ear yourself with a bud, a pick or a home syringe. If you have already tried and it is worse, that is common and nobody will be annoyed with you; just come in and say what you did, because it changes what we look for.
Come the same day, without waiting, if you have sudden hearing loss in one ear, severe ear pain, discharge with fever, dizziness with vomiting, facial weakness, a swollen tender area behind the ear, or an injury to the ear. If we are closed, go to a hospital emergency department. For anything life-threatening, call 999.
For children, bring an account of what you have noticed rather than only what they report — not responding when called, wanting the volume louder, tugging at an ear, poor school performance, or speech that seems to be lagging. Those observations are frequently more diagnostic than anything the child can say.
For pricing on wax removal, audiometry or occupational hearing surveillance, contact the clinic. Teleconsultation at RM30 prepaid is available if you want to ask a question first, though ears fundamentally need to be looked into, and a video call cannot do that.
