  1. Home / Ear Infection (Otitis Media)
  1. Acute otitis media (AOM) is an acute, suppurative infectious process marked by the presence of infected middle ear fluid and inflammation of the mucosa lining the middle ear space. The infection is most frequently precipitated by impaired function of the Eustachian tube, resulting in the retention and suppuration of retained secretions. AOM may also be associated with purulent otorrhea if there is a ruptured tympanic membrane. AOM usually responds promptly to antimicrobial therapy.
  2. Chronic otitis media (COM) is a recurrent infection of the middle ear and/or mastoid air cell tract in the presence of a tympanic membrane perforation. Symptoms commonly associated with chronic ear disease include hearing loss, otorrhea, aural fullness, otalgia, and occasionally true vertigo.
  3. Cholesteatoma, a keratinized mass in the middle ear or mastoid, may occur either as a primary lesion or secondary to tympanic membrane perforation. Mastoiditis may occur as a complication of acute otitis media (AOM) or COM.
