Recurrent ear infections in adults
Adults with ear infections that keep coming back usually have recurrent otitis externa - driven by moisture, cotton buds, eczema or hearing aids - and breaking the cycle is about canal care as much as treatment.

Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
The ear canal is a warm cul-de-sac whose defences - acidic wax and intact skin - are undone by swimming, aggressive cleaning, eczema and occlusive earbuds or hearing aid moulds; each infection inflames the skin, prompting more scratching and cleaning, and the cycle establishes itself. Middle-ear infections recurring in adulthood have a different logic, driven by Eustachian tube dysfunction - and when one-sided, they require a look behind the nose.
Diagnosis and treatment routes
Management splits by site: recurrent otitis externa is treated with thorough microsuction cleaning, appropriate antibiotic-steroid drops, treatment of underlying skin disease, and a strict prevention regime - dry ears (hairdryer on cool, swim plugs), nothing in the canal, acidifying drops after water; hearing aid users benefit from vented moulds and alternating ears where possible. Recurrent otitis media prompts tympanometry, nasoendoscopy of the postnasal space and, for persistent effusion, consideration of a grommet. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant ENT surgeon. Your GP can refer you on the NHS, or you can arrange a private consultation directly.

Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any of the emergency symptoms described above.
Frequently asked
Common questions about Recurrent ear infections in adults.
Quick, plain-English answers to what people ask us most.
-
What causes recurrent ear infections in adults?
Adults with ear infections that keep coming back usually have recurrent otitis externa (outer ear infection), driven by factors such as excess moisture, cotton bud use, and skin conditions affecting the ear canal, rather than typical middle ear infections seen in children.
-
Why do cotton buds contribute to recurrent ear infections?
Cotton buds can push wax deeper, damage the delicate skin lining the ear canal, and remove the ear's natural protective wax barrier, all of which increase susceptibility to infection - which is why they're generally discouraged for cleaning ears.
-
What are the symptoms of recurrent otitis externa?
Symptoms include ear pain, itching, discharge, and sometimes temporary hearing reduction, typically recurring repeatedly, often related to identifiable triggers like swimming, humidity, or ear canal irritation.
-
Is recurrent otitis externa dangerous?
It's not usually dangerous, but frequent infections can be uncomfortable and disruptive, and in rare cases (particularly in people with diabetes or weakened immune systems), it can progress to a more serious infection, so persistent cases need proper assessment.
-
How is recurrent otitis externa treated?
Treatment for individual episodes typically involves antibiotic and/or steroid ear drops, while preventing recurrence focuses on keeping ears dry, avoiding cotton buds and other ear canal trauma, and addressing any underlying skin conditions.
-
How can recurrent ear infections be prevented?
Keeping ears dry (using earplugs when swimming, drying ears gently after washing), avoiding cotton buds or other objects in the ear canal, and treating any underlying skin conditions like eczema affecting the ear can all help reduce recurrence.
-
Recurrent otitis externa vs middle ear infections - what's the difference?
Otitis externa affects the ear canal itself and is often related to moisture and skin irritation, while middle ear infections (more common in children) occur behind the eardrum and are usually linked to upper respiratory infections - they need somewhat different treatment approaches.
-
Can ear wax buildup contribute to recurrent infections?
Yes, excessive or impacted ear wax can trap moisture and create conditions favourable for infection, so appropriate (non-cotton-bud) ear wax management can be part of preventing recurrence.
-
How long does an episode of otitis externa take to clear up?
With appropriate ear drop treatment, most episodes improve within a week to ten days, though it's important to complete the full course of treatment and keep the ear dry during this time.
-
When should I see a specialist about recurrent ear infections?
See an ENT specialist if ear infections are frequent, severe, or not responding well to standard treatment. A private ENT consultation is often available within about two weeks, compared with potentially longer NHS waiting times.
