Hearing aids and otitis externa

Around two million people wear hearing aids in the UK. A common problem with hearing aids is that their use can result in OE and this can be difficult to treat without removing the hearing aids and allowing the ear to ‘dry out’.

Although not using hearing aids for a length of time may be a nuisance, hearing aids can obstruct proper ventilation. Also, there may be discharge from the ears, which can build up if hearing aids are not removed. Hearing aids may also stimulate wax production as the body tries to clear the debris. Generally, it is better to remove hearing aids while ear preparations for treating OE are used.

Some tips for preventing OE in hearing aid users are as follows:

• Take out hearing aids at night to allow the devices and the ears to dry out
• Regularly clean and disinfect hearing aids using manufacturer-recommended methods and products. Avoid using harsh chemicals for cleaning. Ensure thorough drying to prevent moisture build-up – this may involve a UV light dryer for added protection
• Maintain good ear hygiene by gently cleaning the outer ear with a washcloth and avoid using cotton buds, which can push wax deeper into the ear canal
• Have regular check-ups with an audiologist to ensure proper fitting and function of hearing aids. An audiologist can also inspect for any signs of infection or irritation
• Minimise exposure to environmental irritants such as cigarette smoke, allergens and pollutants, which can exacerbate ear inflammation
• Consider using hypoallergenic hearing aid materials for ear moulds.
