External Ear Inflammation
External ear inflammation, also known as otitis externa, refers to an inflammatory condition affecting the external auditory canal, which can be caused by either bacterial or fungal infections.
Causes of Bacterial Infections in the External Ear
Poor ear hygiene or the use of unsterilized instruments for cleaning the ear can lead to bacterial infections. For instance, some individuals may resort to using makeshift tools such as keys, which can inadvertently cause abrasions in the external auditory canal. These injuries create a pathway for bacteria from contaminated instruments to enter, resulting in infection and inflammation of the ear.
Causes of Fungal Infections in the External Ear
- Swimming
- Individuals with compromised immune systems, such as those suffering from conditions like diabetes or cancer, particularly patients undergoing chemotherapy, are at an increased risk for fungal infections. Their weakened immune responses make them more susceptible to this type of ear inflammation compared to the general population.
It is crucial to accurately determine the underlying cause of the inflammation—whether it be bacterial or fungal—as this will guide the appropriate treatment approach.
