Hearing aids can be life-changing, reconnecting you to the sounds and people you love. However, wearing a device in your ear canal daily can sometimes lead to an unexpected side effect: issues with earwax. Understanding this relationship is key to keeping your hearing aids working optimally and your ears healthy. While it might seem like a minor inconvenience, impacted wax can interfere with your device’s performance and cause discomfort.
How hearing aids can cause wax build-up
Your ears have a natural, self-cleaning process. Earwax, or cerumen, is produced by glands in the outer third of your ear canal. It traps dust and debris, and then slowly migrates out of the ear, carrying the trapped particles with it. Wearing a hearing aid can disrupt this process in a few ways. The presence of an ear mould or dome can stimulate the cerumen glands, causing them to produce more wax. It also acts as a barrier, preventing the wax from migrating out naturally. Furthermore, each time you insert your hearing aid, you can unintentionally push existing wax deeper into the ear canal, leading to blockages.
Signs that wax is interfering with your hearing aid
When earwax begins to build up, it can directly affect how well your hearing aids function. One of the most common signs is a whistling or feedback sound. This occurs when amplified sound escapes the ear canal, is picked up by the hearing aid’s microphone, and is re-amplified, creating a feedback loop. A wax blockage can prevent sound from travelling down the ear canal, forcing it back out. You might also notice that sounds seem muffled or distorted, or that your hearing aid seems to have lost power, even with a fresh battery. In some cases, the build-up can cause itching, a feeling of fullness, or physical discomfort.
Daily care and what to avoid at home
Proper daily hygiene is essential for preventing wax-related problems. At the end of each day, gently wipe the ear mould or dome of your hearing aid with a soft, dry cloth to remove any visible wax and debris. Most modern hearing aids also come with small wax guards or filters that protect the internal components. Learn how to check and change these regularly according to your manufacturer's instructions. A common mistake is using cotton swabs to clean your ears; these tools often push wax deeper into the canal, worsening the problem. It is also crucial to avoid inserting any other objects into your ears, as this can cause serious injury.
When to seek professional ear wax removal
If you suspect a wax build-up is affecting your hearing or device, it’s time to seek professional help. While over-the-counter softening drops can be useful for some, they should be avoided if you have a history of ear infections, a perforated eardrum, or grommets. A qualified clinician can safely assess your ears and recommend the best method for ear wax removal. Trying to remove impacted wax yourself can be dangerous and ineffective. Scheduling a professional check-up is the safest course of action.
Professional options for safe wax removal
Clinicians have several methods for removing impacted wax. Ear wax microsuction is often considered the gold standard, especially for hearing aid users. This procedure involves using a microscope for a clear view of the ear canal while a tiny, medical-grade suction device gently removes the wax. It is precise, dry, and generally very safe. Another method is ear syringing or irrigation, where a controlled stream of warm water is used to flush out the wax. However, this is not suitable for everyone, particularly those with a history of ear problems. A third option is manual removal using specialised tools like fine curettes, performed under direct visualisation by an expert.
Staying proactive with your ear health
For hearing aid users, proactive maintenance is better than reactive treatment. It is a good idea to have your ears professionally checked for wax every three to six months. If you know you produce a lot of wax, you might need more frequent appointments. Regular professional cleanings not only keep your hearing aids working their best but also prevent discomfort and potential damage to your ears. By partnering with an audiologist or a qualified ear care professional, you can create a simple maintenance plan that works for you, ensuring clear hearing and healthy ears for years to come.
