Ear Infections and Hearing Aids: Discover the symptoms, preventions, management, and treatments available

Hearing Aids and Ear Infections 

What is an ear infection and could my hearing aids cause it?

Ear infections

Ear infections, also known as otitis, are a common illness that affects many worldwide and are often caused by bacteria or viruses. It typically results in pain, fluid buildup, and sometimes hearing loss. Common in children, symptoms include ear pain, fever, and irritability.  Treatment for ear infections usually involves antibiotics or pain relievers.

Here, we briefly talk about the various forms of ear infections, their connection to hearing aids, symptoms, causes, prevention strategies, and how to manage them effectively.

What is an ear infection?

An ear infection is an inflammation of the ear.  They often occur when bacteria or a virus infects the space behind the eardrum, causing irritation and pain.  For those with hearing loss who wear hearing aids, the risk of developing ear infections may increase.

Though wearing hearing devices does not directly cause ear infections, moisture build-up, and improper cleaning of devices can. This is due to bacteria living and growing on the hearing aids.

Ear infections are especially common among children, but, in reality, can affect those of any age. The symptoms often present themselves suddenly and can last up to seven days once a treatment, such as antibiotics, has been prescribed.

It is important to seek treatment as soon as symptoms develop.  If left untreated, the infection could spread. In severe (although rare) cases, this can spread to the bone and cause abscesses, permanent damage to the ear, and hearing loss through the narrowing of the ear canal.

What are the generic symptoms of an ear infection in adults?

• Ear pain, discomfort, or ‘fullness’ of the ear
• Discharge from the ear
• Reduced hearing ability
• Fever
• Balance issues or dizziness
• Nasal congestion
• Vomiting
• Diarrhea

Middle ear infection causes, and symptoms

This is a common type of ear infection, known as Otitis Media.  It affects the air-filled space behind the eardrum housing the tiny vibrating bones called ossicles. This infection occurs when fluid becomes trapped behind the eardrum, often as a result of colds, flu, or allergies.  Upper respiratory issues, such as sinus or throat infections, can also contribute to the development of middle ear infections. 

Eustachian tubes connect the middle ear to the back of the throat and the nasal passages, helping to regulate air pressure in the middle ear.  Middle ear infections can cause these tubes to swell and stop natural drainage.  The trapped fluid in the tubes can accumulate in the middle ear, leading to infection of the middle ear.

The typical signs to look out for include ear pain, difficulty hearing, pressure in the ear, discharge from the ear, and sometimes fever.

What is an inner ear infection?

An inner ear infection, also known as labyrinthitis, occurs when the labyrinth deep inside the ear becomes inflamed. This could also be caused by a virus, bacteria, congestion after a cold, or when a middle ear infection spreads.

This inflammation can interfere with the transmission of sensory information from the inner ear to the brain. It is this interruption that may lead to symptoms associated with labyrinthitis and also worsen the effects of hearing loss.

Outer ear infection, causes, and symptoms

Outer ear infection, also known as Otitis Externa or Swimmer's Ear, is an infection that extends from the ear canal entrance to the eardrum.  It develops when water remains in the ear after activities like swimming or bathing, creating an ideal environment for bacterial growth.  Bacterial infections in the outer ear can also occur if the skin is scratched or irritated, highlighting the importance of not inserting objects into the ear.

Typical symptoms of an outer ear infection include ear pain, tenderness, redness, and swelling. Such infections can cause discomfort and swelling in the ear canal, which can interfere with the fit and comfort of hearing aids.

Outer ear infections may also affect hearing quality, making the use of certain hearing aids uncomfortable. These symptoms can persist for several days or even weeks.

Why do my hearing aids give me earache?

Is there a link between hearing aids and ear infections?

Are those with hearing aids more likely to get ear infections?

Hearing aids, essential for those with hearing loss, can’t directly cause ear infections but can contribute to them if not properly maintained.  When hearing aids are not inserted in the ear correctly, they might leave your ears irritated and cause pain.

If you are experiencing pain with new hearing aids, it is important to remember that it does take time to adjust to them. This is known as hearing aid newness.  For tips on how to adapt to new hearing aids, please read our guide here.

Factors linking hearing aids to ear infections include:

• Moisture build-up: Sweat, humidity, and moisture can accumulate in hearing aids, creating a breeding ground for bacteria.
• Excessive earwax: Improper cleaning of hearing aids can lead to the build-up of earwax, which can trap moisture and harbour bacteria.
• Fit and comfort: Ill-fitting hearing aids can cause irritation or pressure in the ear canal, potentially increasing the risk of infection. Make sure you contact your audiologist who will be happy to help you with a better fitting and placement.

Causes of ear infections

Several factors can contribute to the development of ear infections, including:

• Bacterial or viral infections: Common colds, respiratory infections, or allergies can lead to the blockage of the eustachian tube, causing fluid build-up and infection.
• Anatomy: Children, in particular, have shorter and more horizontal eustachian tubes, making them more prone to infections.
• Allergies: Allergic reactions to environmental factors such as pollen, dust, or pet dander can trigger inflammation and lead to ear infections.

Preventing ear infections in hearing aid wearers

Prevention is key to reducing the risk of ear infections, especially for those who rely on hearing aids.  Here are some effective prevention strategies for hearing aid wearers:

• Proper cleaning and maintenance: Regularly clean and disinfect hearing aids using manufacturer-recommended methods and products. Ensure thorough drying to prevent moisture build-up. If you are prone to bacterial infections, this could include a UV light dryer for added protection.
• Cleaning resources: Learn how to properly maintain and clean your hearing aids at home here.
• Ear hygiene: Maintain good ear hygiene by gently cleaning the outer ear with a washcloth and avoid using cotton swabs, which can push wax deeper into the ear canal.
• Regular check-ups: Schedule routine check-ups with an audiologist to ensure proper fitting and function of hearing aids. They can also inspect for any signs of infection or irritation.
• Avoid irritants: Minimise exposure to environmental irritants such as cigarette smoke, allergens, and pollutants, which can exacerbate ear inflammation.
• Avoid allergens: Look for hypoallergenic hearing aid materials for earmoulds and avoid using harsh chemicals to clean the hearing aids.

Should I wear my hearing aids if I have an ear infection?

Even if you take all preventive measures, those using hearing aids may still experience ear infections. Audiologists recommend not to wear your hearing aids when suffering from an ear infection.

This is because swelling and sensitivity in the ears can intensify the symptoms and cause further discomfort when wearing the devices. Hearing aids can obstruct proper ventilation, which is helpful for the ear's recovery.

There may be discharge from the ears which hearing aids can cause, it then builds up and can cause excessive earwax.  This is because your body produces more of it in an attempt to naturally clear the infection. 

Can I use eardrops if I wear hearing aids?

Ideally, don’t use eardrops at the same time as wearing hearing aids (unless instructed otherwise by your audiologist or health care practitioner).  The hearing aids can cause the moisture to stay in the ear longer than advised. This can promote the growth of bacteria in the ear, a known contributor to ear infections.

Managing Ear Infections with Hearing Aids

What to do if you are experiencing symptoms of an ear infection

Our recommended steps to take are:

• Seek prompt medical attention: Your GP can diagnose the condition and prescribe appropriate treatment, which may include antibiotics or ear drops.
• Take over-the-counter painkillers: Easily accessible painkillers such as Paracetamol and Ibuprofen will help to lessen the painful symptoms of an ear infection. 
• Apply heat: Holding something warm against the ear, such as a heat pack, can also ease the pain.  Ensure the heat pack isn't too hot before pressing against the ear.
• Raise your head: Try sleeping on two or more pillows to aid with congestion and drainage.
• Stop wearing your hearing aids: Our audiologists would recommend temporarily discontinuing the use of hearing aids. This will help air to circulate easily and avoid further build-up, enabling the ear to heal. If you are unsure, follow the guidance of your own healthcare professional.  They will explain when it is safe to resume the use of your hearing aids.
• Avoid inserting anything into the ear: Don’t be tempted to ‘clean’ the infection away, avoid inserting anything into the ear canal unless instructed by a healthcare provider.

Conclusion

Ear infections can pose challenges for people relying on hearing aids, but with proper understanding, preventive measures, and timely management, their impact can be minimised.

By being consistent with good ear hygiene, regular maintenance of hearing aids, and seeking prompt medical attention, when needed, you can enjoy improved hearing health.

Incorporating these ear health habits not only reduces the risk of ear infections but also enhances the effectiveness and longevity of your hearing aids.  By understanding the connection between hearing aids and ear infections, you can take proactive steps to safeguard your future hearing health.
