Earbuds have become an integral part of our daily lives, but their prolonged use raises questions about potential health risks. According to Dr. Michaelides, if earbuds do not fit properly, they can cause irritation in the ear canal. This is especially true when used for extended periods, as moisture can accumulate, making the ears more susceptible to infection or irritation.
Exploring further, studies have shown that various viruses, such as cytomegalovirus, mumps virus, and hepatitis viruses, can lead to deafness. However, the specific mechanisms of how these infections affect the inner ear remain unclear. This lack of understanding sparked a collaborative project between Gehrke and Stankovic, aiming to develop cellular models to study human inner ear infections.
One common type of ear infection is swimmer’s ear, an infection of the outer ear canal often triggered by moisture that fosters bacterial growth. It is frequently seen in individuals who spend a lot of time in water. The standard treatment for swimmer’s ear involves medicated antibiotic eardrops.
Ear infections can also result from a buildup of fluid behind the eardrum, causing inflammation. These infections are more prevalent in cooler months due to colds, flu, allergies, and other upper respiratory issues leading to fluid accumulation and blockage.
Temporary hearing loss has several causes, with fluid in the middle ear due to infections being the most common. Other factors include eardrum perforation from severe infections or trauma and narrowing of the ear canal from surgery or disease.
Interestingly, the three most common bacteria causing middle ear infections in children aged 6 months to 5 years are Haemophilus influenzae, Streptococcus pneumoniae, and Moraxella catarrhalis. Notably, before the introduction of pneumococcal vaccines, Streptococcus pneumoniae was responsible for 60% to 70% of all ear infections in this age group.
Additionally, environmental factors like wildfire smoke can irritate not only the lungs and throat but also the ears. Dr. Albert Merati, a UW Medicine otolaryngologist and head and neck surgeon, emphasizes the interconnectedness of the ears, nose, and throat, noting that the lining of the nose and ear can be particularly sensitive to such irritants.
