What is otitis media (middle ear infection or inflammation)?

Otitis media is inflammation of the middle ear; however, many doctors consider otitis media to be either inflammation or infection of the middle ear. "Otitis" means inflammation of the ear, and "media" means middle. This inflammation often begins with infections that cause sore throats, colds or other respiratory problems, and spreads to the middle ear. Infections can be caused by viruses or bacteria, and can be acute or chronic.

Acute otitis media is usually of rapid onset and short duration. Acute otitis media is typically associated with fluid accumulation in the middle ear together with signs or symptoms of ear infection; a bulging eardrum usually accompanied by pain, or a perforated eardrum, often with drainage of purulent material (pus, also termed suppurative otitis media). Fever can be present.

Chronic otitis media is a persistent inflammation of the middle ear, typically for a minimum of 3 months. This is in distinction to an acute ear infection (acute otitis media) that usually lasts only several weeks. Following an acute infection, fluid (an effusion) may remain behind the ear drum (tympanic membrane) for up to three months before resolving. Chronic otitis media may develop after a prolonged period of time with fluid (effusion) or negative pressure behind the eardrum (tympanic membrane). Chronic otitis media can cause ongoing damage to the middle ear and eardrum, and there may be continuing drainage through a hole in the eardrum. Chronic otitis media often starts painlessly without fever. Ear pressure or popping can be persistent for months. Sometimes a subtle loss of hearing can be due to chronic otitis media.
