Recent investigations into the etiology and pathogenesis of external otitis have brought about a more rational method of therapy and possibly prophylaxis. Studies of the bacteriology and mycology of external otitis have been going on for many years. It has been only during the past few years, however, that interest has been directed toward explaining why this condition is so characteristically recurrent. The antibiotics and their peculiar bacterial spectra of activity have changed our mode of thinking. When we are confronted with an infectious process we now ask ourselves the following: What is the organism? Is it pathogenic, and to what antibiotic is it sensitive? Since we have been armed with this information pathogenic organisms have become an easy prey to our drugs—a far cry from the practice of medicine several years ago.
All the recent investigations have uniformly reported that the vast majority of cases of external otitis are
