Inflammation of theear canal(otitis externa)
Causes, symptoms, and therapy
An inflammation of the ear canal (also otitis externa) is defined as a bacterial, fungal, or allergic inflammation of the skin and subcutis in the outer ear canal. In some cases, an inflammation of the ear canal can also involve the outer ear or the tympanic membrane (eardrum). The latter is known as myringitis. It is a medical health issue and should be dealt with in the correct manner to ensure there is no further damage.
Causes of an ear canal inflammation
A trigger for an inflammation of the ear canal (otitis externa) is microtrauma. This term describes minor injuries to the skin, caused by, for instance, rigorous cleaning of the ear using a cotton swab, damaging the dermis of the ear canal.
Another factor for the inflammation of the ear canal can be skin sensitization (an allergic reaction) as caused by certain shampoos and other artificial agents like hairsprays and soaps. Additionally, increased ossification (exostoses of the ear canal) or a chronic middle ear infection can be at the root of the condition. Diseases resulting in immunodeficiency – for example, neurodermatitis, psoriasis, and diabetes mellitus – can, by way of a general skin inflammation (dermatitis), also lead to an inflammation of the ear canal.
One other thing that can cause this medical condition could be not looking after your ears and hearing aids properly. Hearing aids wearers need to be aware that by wearing a hearing device they are closing up the ear, making it easier for infections to spread. Therefore, it is important to regularly clean your ear of any wax and moisture. But, also clean your hearing devices regularly to ensure any bacteria is cleaned off. When you are fitted with hearing aids, the audiologist should go over the cleaning procedure and you should follow that procedure every week to prevent potential infections.
Can I wear hearing aids?
Many people find that when suffering from this medical condition they can’t wear hearing aids. This is because putting in an external object in the ear can cause infections and can be a painful experience for the wearer. People are advised to get a suitable treatment for their case and wait a few weeks before wearing a hearing device. This means that they are unable to hear properly until the treatment is done. However, in the long-term it proves to be advantageous as the wearer doesn’t have to suffer from extra pain or infections.
