👉 Ependymitis is a condition that occurs when the lining of the space between the eardrum and the middle ear, known as the eardimenter, becomes inflamed or swollen. This can occur due to various factors such as infection, inflammation, or trauma. The eardimenter is responsible for distributing sound waves from the outer ear into the inner ear, allowing us to hear it. Ependymitis can cause pain and discomfort when you listen to music or speak loudly,
