The most common types of ear infections are acute otitis media, chronic otitis media and otitis externa. Acute otitis media is an infection of the middle ear that typically lasts for a few days to a week or two and can cause hearing loss. Chronic otitis media is an infection of the middle ear that persists for more than three months and can lead to permanent hearing loss. Otitis externa is an infection of the outer ear canal that causes inflammation, pain and discomfort.
