What is otitis externa commonly referred to as?

Otitis externa is commonly referred to as "Swimmer's ear" because it is an inflammation or infection of the outer ear canal, often associated with water exposure. This condition typically occurs when water remains trapped in the ear canal, creating a moist environment that fosters bacterial growth. The term "Swimmer's ear" emphasizes the common link between swimming or water activities and the occurrence of this ailment.

The other terms listed refer to different ear-related conditions: a middle ear infection is known as otitis media, tinnitus refers to a perception of noise or ringing in the ears, and cholesteatoma is an abnormal skin growth in the middle ear that can lead to hearing loss. Understanding these distinctions helps in recognizing the specific nature and causes of each condition.
