H60: Otitis externa

H60.5: Acute otitis externa, noninfective

The ear consists of 3 sections: the outer ear, the middle ear, and the inner ear. The auricle and the auditory canal are part of the outer ear. The auricle and auditory canal route sound from outside towards the middle ear.

You have an inflammation in your auricle or your auditory canal. When the outer ear is inflamed, the ear may be itchy or sore. One’s hearing may also be worse than usual.

Your outer ear has become inflamed. The outer ear can also become inflamed due to certain chemicals or radiation. Certain skin conditions can also affect the ear. If someone has an allergy, the ear may also become inflamed as a result.
