What type of infection is classified as otitis externa?

Otitis externa is specifically defined as an infection or inflammation occurring in the external ear canal, which extends from the outer ear to the eardrum. This condition is often referred to as "swimmer's ear," and it can result from water exposure, irritation, or infection. The distinction in this classification is important because it focuses on the outer part of the ear rather than the middle ear or other body parts.

In contrast, a middle ear infection refers to otitis media, which affects the area behind the eardrum. Infection around the nail pertains to paronychia, and inflammation of the skin can describe a variety of conditions but is not specific to the infection of the external ear canal. Understanding these classifications helps in accurate diagnosis and treatment of ear-related conditions.
