Otitis externa is the medical term for an infection of the external auditory canal, also known as swimmer's ear. Symptoms can include pain, itching, and redness of the ear canal. Treatment typically involves antibiotic ear drops.
The fine hairs in the external auditory canal help to trap and prevent debris, such as dust and particles, from entering the ear. This helps to keep the ear clean and prevent blockages. The tiny wax-producing glands in the external auditory canal secrete earwax (cerumen) which helps to lubricate and protect the ear canal from infection and irritation.
Another name for the ear canal is the external auditory meatus. The ear canal is a tube that runs from the outer ear to the middle ear.
