The most common types of ear infections are acute otitis media, chronic otitis media, and acute otitis externa. Acute otitis media is a bacterial infection that occurs when fluid builds up in the middle ear space. This can cause hearing loss and pain in the ear. Chronic otitis media is an inflammation of the middle ear that can last for months or years. Acute otitis externa is caused by bacteria that enter the outer ear canal. It causes itching, pain, and swelling of the ear canal.
