- Otitis externa - all the dangers of the disease
Malignant otitis externa
Malignant otitis externa - is one of the rarest and most serious complications of otitis externa. The first symptoms of the disease have been described in 1838, but even then, many decades later, researchers could not pinpoint the cause of their appearance. Only in 1968 malignant otitis externa has been defined as a distinct disease and its clinical signs were described in detail. The disease has been called malignant because of its aggressive course, a very poor prognosis and high mortality among patients. When were effective antibiotics for the treatment of otitis externa, forecasts have become much more favorable. Frightening name of the disease, although it is not related to cancer, left, and perhaps for good reason - this form of otitis media still can lead to very serious consequences for health.

For example, in the UK in 2012 and 2013 malignant external otitis was diagnosed, in total, 810 people, and more than 700 of these patients were older than 60 years. In general, malignant otitis media is much more common in countries with warm and humid climates than in cold and dry areas.
Approximately 90% of patients with this disorder suffer from diabetes. Currently, diabetes (both first and second type) is considered the most significant risk factor for the development of malignant otitis externa. The predisposition to the development of this disorder is not necessarily related to the severity of forms of diabetes in an individual patient.
