Otitis externa associated with aquatic activities (swimmer's ear)

Infections of the ear canal may vary in terms of severity. Their frequency and morbidity qualify them as significant aquatic problems. The aquatic environment adds the conditional variable of moisture to the ear canal. Usually bacteria are introduced with the moisture and in the warm environment of the canal multiply, generate debris, invade the canal lining, and generate the symptoms of otitis externa. Fortunately, the incidence of this condition can be minimized by eliminating moisture in the canal. In situations where excessive moisture is likely to be introduced such as in swimmers, scuba divers, and deep sea divers the prophylactic measures of desiccation and acidification of the canal should be used. They are very effective. In the saturation diver, ear canal infections are not likely to resolve without interruption of diving activities. Individuals who have recurring ear canal infections require evaluation by an ear specialist to identify possible remedial problems that can trigger infection. Correction of anatomical problems or underlying dermatoses can prevent recurrences of OE.
