Abstract

 

Malignant otitis externa is an inflammatory condition caused by Pseudomonas infection of the ear canal with involvement of the temporal bone. It is usually seen in elderly patients with diabetes or patients with immunosuppression. Characteristically the patient presents severe pain and an external canal often edematous, inflammed, and coated with exudate. If the condition is not promptly treated lower cranial nerve palsies can develop due to subtemporal extension of the infection. Treatment consists of prolonged administration (i.e. 6-8 weeks) of an anti-pseudomonal antibiotic (usually oral ciprofloxacin), but recently the emergence of resistant strains have been described.
