Abstract:
Owing to the severity of its corrosive effects, an alkaline hearing-aid battery in the external auditory meatus is an otological emergency. This report emphasizes the particular risk to confused elderly patients and points out that a delay in diagnosis is common. Aetiology, clinical features and treatment are discussed with reference to three recent cases.
