Chronic myringitis with chronic otitis media

  • In cases of adverse courses of the inflammatory process, perforation of the TM persists. Persisting perforation is one characteristic sign of chronic otitis media (COM).

  • Chronic inflammation of the TM accompanies inflammation of the middle ear. On the surface of the TM, the epidermis is actively displaced into the ear canal, and, in 15% of cases, it may penetrate through small perforations of the TM. As a result, the middle ear is isolated, with resulting long-term hearing impairment.

  • This takes place in cases in which the speed of mucosal displacement and that of epidermal displacement coincide. If perforation of the TM is considerable, the epidermis and the mucous membrane meet on the edge of the perforation.

  • Some evidence exists that chronic otitis media may be related to extra-esophageal reflux. [3]
