External Otitis means any type of infection of the outer ear canal. External otitis is different than the infection caused by fluid behind the eardrum (otitis media). There are generally two types of external otitis:
- acute or infectious external otitis
- chronic external otitis
Acute external otitis is also known as "swimmer's ear" because of its association with swimming in fresh waters. Acute external otitis is an infection by multiple types of bacteria and fungi. External otitis can occur in children or adults. If not treated, acute external otitis may spread to the cartilage and bone around the ear canal.
Chronic external otitis is caused by irritation of the skin of the outer ear canal. Although it also may become infected by bacteria or fungi, chronic external otitis is primarily a problem of the skin. Chronic external otitis is associated with other skin disorders outside the ear such as eczema, dermatitis, or psoriasis. Dr. Pasha may also refer you to a Dermatologist (skin doctor) if you have persistent problems.
