External Otitis (Acute)
Prevention of Acute External Otitis
External otitis often can be prevented by applying a few drops of a 1:1 mixture of rubbing alcohol and white vinegar (as long as the eardrum is intact) immediately after swimming. The alcohol helps remove (evaporate) water, and the vinegar alters the pH of the canal. Use of cotton swabs or other implements in the canal should be strongly discouraged.
