title: Otitis externa and myringitis due to demodicidosis.
abstract: We report on an 84-year-old woman with chronic pruritic otitis externa and myringitis. Microbiological and mycological investigations failed to establish the cause, but histology revealed a large amount of Demodex mites. Topical treatment for this ectoparasite resulted in a complete remission. The myringitis was eventually treated successfully with myringoplasty. To the best of our knowledge this is the first case report on Demodex-induced otitis externa and myringitis.
