An adolescent patient who is on the school swim team asks a nurse about ways to prevent swimmer's ear. The nurse will tell the patient to:
a. allow the ears to drain well after every swim and shower.
b. clean the ears with a cotton-tipped appli-cator after swimming.
c. keep the ear canals free of cerumen.
d. use antifungal ear drops before and after swimming.
A
Acute otitis externa (OE) can be minimized by keeping the natural defenses of the external audi-tory canal (EAC) healthy. Swimmers should be taught to dry the EAC after showering and swimming. Cleaning the ears with cotton-tipped swabs can remove the cerumen and abrade the epithelium. Removing cerumen removes the natural barrier to infection. Antifungal ear drops are used to treat acute OE but not as a preventive measure.
