Some research suggests using ear plugs when swimming.^{1,6,16,19,22,25} Other research indicates this might actually increase the risk of infection by traumatizing the skin.^8,9,21 Swimming caps have been suggested as an alternative way to exclude water from the ear.^8,21 However, occlusive head gear has also been associated with external ear infections.26 If any type of ear plug is to be worn, cotton wool smeared with petroleum jelly is as effective at keeping water out as more expensive devices.²⁵

Although AOE is generally a mild illness, it is a frequently diagnosed condition responsible for a substantial burden in health care dollars and clinicians’ time. Passing along a few simple messages to our patients and their families can help prevent some future cases of AOE. Swimming is a healthful activity that should be encouraged. We can help keep kids active and healthy by giving patients and their parents ideas on how to prevent future cases of swimmer’s ear.
