Fluid coming from the ear can be worrying, especially when it affects a child. Ear discharge, medically known as otorrhoea, may appear watery, thick, yellow, white, blood-stained or foul-smelling. While water or softened earwax can sometimes come out of the ear without indicating a serious problem, persistent discharge may be a sign of infection, injury or a perforated eardrum.

The colour of the discharge alone cannot confirm its cause. An examination by an ENT specialist may be needed, particularly when discharge is accompanied by pain, fever, hearing changes or dizziness.

What Is Ear Discharge?

Ear discharge refers to any fluid that comes out through the ear canal. Depending on the underlying condition, it may consist of:

• Earwax

• Clear or watery fluid

• Pus

• Blood

• A combination of fluid and debris

Normal earwax is generally yellow, orange or brown and has a wax-like texture. Fluid that is unusually watery, thick, foul-smelling or mixed with blood should not be assumed to be ordinary earwax.

Common Causes of Ear Discharge

1. Middle-Ear Infection

A middle-ear infection, or otitis media, develops behind the eardrum. It is especially common in children, often following a cold or respiratory infection.

Infected fluid can build up behind the eardrum and create pressure. Occasionally, this pressure produces a small tear in the eardrum, allowing pus or fluid to drain into the ear canal. Ear pain may reduce after drainage begins, but this does not necessarily mean that the infection has resolved.

Other symptoms can include:

• Ear pain or pressure

• Fever

• Reduced hearing

• Irritability in young children

• Difficulty sleeping

• Poor feeding

• Rubbing or pulling the affected ear

2. Outer-Ear Infection

An outer-ear infection, also called otitis externa or swimmer’s ear, affects the ear canal. It can develop when water remains inside the ear after swimming or bathing, creating a moist environment for germs.

Scratching the ear or inserting cotton buds and other objects can also damage the ear-canal skin and increase the risk of infection.

Possible symptoms include:

• Pain when touching or pulling the outer ear

• Itching

• Redness or swelling

• A blocked sensation

• Discharge from the ear

• Temporary reduction in hearing

3. Perforated Eardrum

A perforated eardrum is a hole or tear in the thin membrane separating the outer ear from the middle ear. It may result from:

• A middle-ear infection

• Inserting objects into the ear

• A sudden pressure change during flying or diving

• Exposure to an extremely loud sound

• A direct blow or injury to the ear

A perforated eardrum may cause clear fluid, pus or blood to leak from the ear. It can also cause pain, hearing loss, tinnitus or dizziness.NHS

4. Injury to the Ear Canal

Cotton buds, fingernails, hairpins or other objects can scratch the ear canal and cause slight bleeding or watery discharge. Even a small injury can become infected if the ear is repeatedly touched or exposed to contaminated water.

5. Foreign Object in the Ear

Children may insert beads, pieces of paper, small toy parts, food or other objects into their ears. A foreign object can cause irritation, infection and foul-smelling discharge.

Do not attempt to remove an object using tweezers, cotton buds or another instrument. This can push it deeper or damage the eardrum.

6. Chronic Ear Infection

Repeated or untreated middle-ear infections can sometimes cause ongoing discharge through a persistent opening in the eardrum. Chronic ear infection may gradually affect hearing and requires assessment by an ENT specialist.

7. Cholesteatoma

A cholesteatoma is an abnormal collection of skin cells that develops behind the eardrum. It may occur after repeated infections, eardrum damage or previous ear surgery.

Possible symptoms include:

• Persistent foul-smelling discharge

• Gradual hearing loss

• A feeling of pressure inside the ear

• Earache

• Dizziness in some cases

Although uncommon, cholesteatoma can damage structures inside the ear and requires specialist treatment.NHS

8. Ear Surgery or Grommets

Children with grommets may occasionally develop ear discharge because fluid can drain from the middle ear through the small ventilation tube. Discharge following an ear procedure should be reported to the treating doctor, particularly if it persists or occurs with pain and fever.

Why Are Ear Infections Common in Children?

Children have shorter and more horizontal Eustachian tubes than adults. These tubes connect the middle ear to the back of the throat and help drain fluid.

Because the tubes are still developing, they can become blocked more easily during a cold, allergy or respiratory infection. Fluid may then accumulate behind the eardrum and become infected.

Babies and young children may be unable to explain their symptoms. Parents should watch for:

• Pulling or rubbing the ear

• Unusual crying or irritability

• Difficulty sleeping

• Poor feeding

• Fever

• Reduced response to sounds

• Balance problems

• Fluid, pus or blood coming from the ear

Ear drainage in a child can indicate that infected fluid has passed through a small eardrum perforation. The child should be medically evaluated even if the pain appears to have improved.American Academy of Pediatrics

When Should You See an ENT Specialist?

Consult an ENT specialist if the discharge:

• Continues or repeatedly returns

• Is thick, yellow, green or foul-smelling

• Contains blood

• Occurs with ear pain or fever

• Is accompanied by reduced hearing

• Develops after swimming or an ear injury

• Occurs after inserting an object into the ear

• Affects a baby or young child

• Is associated with ringing in the ear

• Appears after a recent ear operation

• Does not improve with previously prescribed treatment

Recurring discharge should not be managed repeatedly with over-the-counter eardrops without identifying its cause.

Warning Signs That Need Urgent Medical Attention

Seek prompt medical care if ear discharge occurs with:

• Sudden or significant hearing loss

• Severe dizziness or difficulty walking

• Swelling or redness behind the ear

• High fever or severe pain

• Facial weakness

• Persistent vomiting

• Severe headache

• A recent major head injury

• Clear watery discharge following a head injury

• Difficulty speaking, swallowing or seeing

• Symptoms in someone with diabetes or a weakened immune system

Discharge following a serious head injury requires urgent assessment and should not be treated at home.

How Is the Cause Diagnosed?

An ENT specialist will ask when the discharge began, what it looks or smells like and whether there is pain, fever, hearing loss, injury or water exposure.

The examination may include:

Otoscopic Examination

An otoscope is used to inspect the ear canal and eardrum for infection, swelling, injury, perforation or a foreign object.

Microscopic Ear Examination

A detailed examination under magnification may help the specialist inspect and carefully clean the ear canal.

Hearing Tests

A hearing evaluation may be advised if the patient notices reduced hearing or has experienced repeated infections.

Laboratory Testing

A sample of the discharge may occasionally be tested when an infection is persistent, severe or unresponsive to treatment.

Imaging

A CT or another imaging test may be recommended if the doctor suspects cholesteatoma, a complication or disease involving deeper ear structures.

How Is Ear Discharge Treated?

Treatment depends on the underlying cause. It may include:

• Professionally cleaning the ear canal

• Prescribed antibiotic or antifungal eardrops

• Oral medication in selected cases

• Keeping the affected ear dry

• Removing a foreign object safely

• Monitoring a perforated eardrum as it heals

• Treating chronic infection

• Surgery for selected cases such as persistent perforation or cholesteatoma

Antibiotics are not required for every ear problem. Medication should be selected only after the ear has been examined, as some eardrops may be unsuitable when the eardrum is perforated.

What Should You Avoid Doing?

Until the ear has been assessed:

• Do not insert cotton buds or other objects

• Do not pour oil, water or home remedies into the ear

• Do not use unprescribed eardrops

• Do not attempt to remove a foreign object yourself

• Do not allow water to enter the affected ear

• Do not ignore discharge because the pain has reduced

Gently wipe fluid from the outer ear with clean cotton or gauze, but do not push anything into the ear canal.

Can Ear Discharge Affect Hearing?

Temporary hearing reduction can occur when fluid, swelling or debris blocks the ear canal. Middle-ear fluid and a perforated eardrum can also interfere with sound transmission.

Hearing often improves after the underlying condition is treated. However, repeated infections, chronic perforation or cholesteatoma can sometimes cause more lasting hearing problems. Early ENT evaluation is particularly important for children because ongoing hearing difficulties may affect speech development and learning.

Conclusion

Ear discharge may be caused by an outer- or middle-ear infection, a perforated eardrum, injury, a foreign object or a chronic ear condition. While some causes are minor, persistent, foul-smelling or blood-stained discharge—especially when accompanied by pain, fever, dizziness or hearing loss—should be evaluated by an ENT specialist.
