Overview
What is impacted earwax?
Earwax (cerumen) is a normal substance produced by glands in the ear canal. It helps protect the skin of the canal and usually works its way out naturally. Impacted earwax occurs when wax accumulates and becomes tightly packed, partially or fully blocking the canal. This can cause discomfort or temporary hearing changes. A clinical assessment helps confirm whether symptoms are due to wax or another cause.
Symptoms
Common symptoms
Symptoms vary from person to person and can overlap with other ear conditions.
A feeling of fullness or blockage in the ear
Muffled or reduced hearing in the affected ear
Ear discomfort or mild pain
Itching in the ear canal
Ringing in the ear (tinnitus)
Dizziness (less common)
A cough triggered by stimulation in the ear canal (uncommon)
Possible causes
Why earwax may become impacted
Several factors can prevent wax from clearing naturally.
Ear canal shape
A narrow, curved, or unusually shaped canal can make it harder for wax to exit.
Objects in the ear
Cotton buds and similar items often push wax deeper rather than removing it.
Devices in the ear
Regular use of hearing aids or earplugs may affect how wax drains.
Wax consistency
Dry or hard wax, including age-related changes, may be more likely to become impacted.
Skin conditions
Conditions such as eczema affecting the ear canal may contribute to wax build-up.
Previous ear surgery
Past ear surgery or an abnormally shaped canal may increase the risk of impaction.
When to seek care
When should I see an ENT specialist?
Seek assessment if symptoms persist or if warning signs are present.
Symptoms continue despite appropriate self-care
Worsening or severe ear pain
Discharge, bleeding, or an unpleasant smell from the ear
Sudden or significant hearing loss
Dizziness or balance problems
A known hole in the eardrum (perforation) or previous ear surgery
Recurrent wax impactions
Diabetes or a weakened immune system with symptoms that may suggest infection
Diagnosis
How is it diagnosed?
An ENT specialist will ask about your symptoms and examine the ear with an otoscope to view the canal and eardrum. This helps confirm wax impaction and rule out other causes, such as infection or a foreign body. Further assessment may be needed if the eardrum cannot be seen clearly.
Treatment
Treatment options
Treatment depends on the amount of wax, the condition of the ear canal, and individual factors. The most suitable approach is chosen after clinical assessment.
Wax-softening drops or sprays
May be used when the eardrum is intact and there is no contraindication, sometimes before planned removal.
Ear irrigation
May be performed by a trained clinician when assessed as appropriate. It is not suitable for everyone.
Clinician removal
Wax may be removed using specialised instruments or gentle suction during an outpatient visit.
Self-care
What you can do at home
Focus on safe habits and avoid actions that may worsen symptoms.
Do not insert cotton buds, hairpins, or other objects into the ear canal
If advised, use wax-softening drops as directed
Avoid unverified remedies such as ear candling
Clean the outer ear with a washcloth; let the canal manage itself naturally
Seek professional assessment if symptoms persist or worsen
Prevention
Reducing the risk of impaction
Impaction cannot always be prevented, but certain habits may help reduce risk.
Avoid putting objects in the ear canal
If you use hearing aids or earplugs, follow cleaning and check-up guidance
Manage skin conditions that affect the ear canal
Return for review if you are prone to repeated wax build-up
FAQ
Frequently asked questions
Common questions about impacted earwax, safe home care, and when to see a specialist.
Is earwax normal?
Yes. Earwax helps protect the ear canal. Problems arise when it builds up excessively and becomes impacted.
Can I remove earwax myself?
Cotton buds often push wax deeper and can injure the canal. Softening drops may help in some cases, but removal should be performed by a trained professional when needed.
Is ear irrigation safe?
When performed appropriately on suitable ears, irrigation can be effective. It is not recommended for everyone—for example, if there is eardrum perforation, infection, or certain canal conditions.
Will the wax come back?
Some people produce wax more quickly or have canal shapes that make impaction more likely. Repeat episodes may require monitoring as advised.
Can impacted earwax cause hearing loss?
It can cause temporary conductive hearing loss that often improves once wax is removed, but outcomes vary between individuals.
