AbstractOtitis externa is a common inflammatory condition of the ear, usually caused by infection and affecting up to 10% of the population. It is especially common in children and is more likely to occur in those who are frequently exposed to water. Swimmer’s ear is a form of otitis externa caused when water is trapped in the ear canal after swimming. Otitis externa not only affects swimmers but also those with eczema or excess earwax. It may even occur from excessive cleaning of the ear canal, contact with chemicals (such as hair spray), or contact with bacteria in hot tubs and Jacuzzis3.
