[Mycosic malignant external otitis due to aspergillus, about 2 cases]

ABSTRACT

Malignant external otitis is a severe uncommon infectious disease of the external auditory canal. Diabetes and immunodepression constitute the principal risk factors. The Pseudomonas aeruginosa is the most common germ. Since it is often a primary bacterial disease, initial mycosic infection is exceptional. However, Aspergillus can cause severe and dangerous forms. The authors reported two cases of mycosic malignant external otitis due to aspergillus. The pretherapeutic check-up included a computed tomography and technetium bone scintigraphy practiced in order to assess the extension. The diagnosis was confirmed by a mycological analysis of auricular sample. Hyperbaric oxygenation and medical treatment associating systemic antimycosic drugs, parenteral antibiotherapy were instituted for both patients. Death occured in one case, due to skull basis osteomyelitis. After 16 months of follow up, the second patient is still alive with no obvious complications
