Swollen Ear Canal: Common Causes, Symptoms and More

What Is the Ear Canal?

The ear is divided into three parts: inner, middle, and outer. The outer cartilage and ear canal make up the outer portion. In general, the ear canal, also known as the auditory canal, is a tube that connects the eardrum with the outer ear. It plays a key role in sending sound to the eardrum in your middle ear from the outer area. In general, your ear canal is relatively exposed to the surrounding environment. That’s why it is protected by many glands that form earwax, a sticky substance that prevents debris, dust, and insects from penetrating the ear canal. [1]
