But one of the unwanted consequences of spending lots of time in the water is ear infections, commonly known as swimmer’s ear. The Cedars-Sinai Newsroom spoke to Abhita Reddy, MD, a pediatric otolaryngologist and head and neck surgeon at Cedars-Sinai Guerin Children’s, about what causes swimmer’s ear, how parents can protect their children, and how physicians diagnose and treat the condition.

What is swimmer’s ear?

Swimmer’s ear, properly known as otitis externa, is an infection of the ear canal where you often have drainage. You can have fluid sitting in the ear canal. Sometimes it looks like fluffy tissue that drains. It can cause discomfort and can also cause hearing impairment if left untreated.

What causes swimmer’s ear?

Swimmer’s ear occurs most commonly in the summertime when people are swimming in contaminated water like lakes or rivers, even sometimes in the ocean. We also see it a lot when people go surfing or do water sports, or when kids are going under water frequently or diving deep. Swimming in chlorinated or saltwater pools is less likely to cause swimmer’s ear.

How do you know if your child has swimmer’s ear?

Parents usually know when their child is getting an external infection like swimmer’s ear when they see drainage coming out of the ear, not something brown that looks like wax, but oftentimes it’s white or yellow, and it can smell bad. Swimmer’s ear is often associated with children having pain in their ear, and sometimes it can be associated with small children not letting you touch their ear, so if you tug at their ear or pull their ear it hurts a lot.

How does swimmer’s ear differ from other ear infections?

The biggest difference between a middle ear infection, known as otitis media, versus an outer ear infection, known as otitis externa, or swimmer’s ear, is that middle ear infections, which are behind the eardrum, do not have drainage coming out unless your child has ear tubes. Usually when children have middle ear infections they tug or pull at their ears, which makes it feel better. They also may develop a fever. The opposite is true with swimmer’s ear, or otitis externa, which hurts when you tug on the ear.

How are these infections treated?

Swimmer’s ear is often treated with ear drops because it’s very easy for the drops to get to the area where the infection is. With middle ear infections we often must treat it with antibiotics because unless you have ear tubes, it’s very hard for the drops to reach the infected area.

How can you prevent swimmer’s ear?

When parents ask me how to prevent their kids from getting swimmer’s ear, it often has nothing to do with swimming at all. I just tell them not to use cotton swabs such as Q-tips in their kids’ ears. When you use Q-tips in your children’s ear, it can offset the pH balance inside the ear canal, or cause small breaks in the canal skin, which can then increase the risk of getting ear infections. It is also helpful to consider using earplugs or swim caps for children. Parents can also try to dry the ear if the ear is very wet after a swim. Parents can use a hair dryer around a shoulder length away from their child’s ear on the lowest setting for about 10 seconds at a time, and that can dry out the ear canal and help prevent swimmer’s ear.
