ABSTRACT

Malignant otitis externa, is a disease whose diagnosis and treatment is a challenge for any specialist. It is a severe infection that affects the ear canal (bone / cartilage) and adjacent soft tissues. Usually affecting immunocompromised patients, being diabetes mellitus the most associated condition with up to 65% of cases. In most cases the causative agent is Pseudomonas aeruginosa. Diagnosis should be based on a medical history and complete physical examination, correlating the findings with laboratory and imaging studies. Antibiotic therapy with activity against P. aeruginosa is the mainstay of treatment. Even with proper diagnosis and treatment it is associated with a mortality rate of 20%. In this article, We report the case of a diabetic patient managed with third-generation cephalosporin pseudomonal activity and a review of the literature.
