Masked diabetic mastoiditis
Abstract:
Seven cases of elderly diabetics suffering from ths so-called 'malignant external otitis' are presented. Chandler (1968) and others consider that this disease is localized to the external ear canal. We do not agree and believe that it is due to a masked middle-ear infection extending through the tympano-mastoid cells to the mastoid process, sparing the antrum and bulging into the floor of the external meatus. In time, extension to petrous apex results in petrositis and a fatal end in many cases.
Insights
This study presents seven cases of malignant external otitis in elderly diabetics. The research suggests this condition originates from a masked middle-ear infection, not just the external ear canal, potentially leading to fatal petrositis.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Diabetology
Background:
- Malignant external otitis (MEO) is a severe infection primarily affecting the elderly and diabetic populations.
- Previous literature, such as Chandler (1968), localized MEO to the external ear canal.
- The pathophysiology and full extent of MEO remain subjects of debate.
