Earwax is a waxy, yellowish substance that lines the inside of your ear canal. The ear canal is the tube that runs from your outer ear to your eardrum. The wax helps protect your ear canal from water, infection, injury, and foreign objects. But too much wax buildup can cause problems. This buildup is called impacted earwax.
Special glands in your ear make secretions that combine with dead skin cells to form earwax. The earwax travels with the slowly growing cells of your skin. Over time, the earwax moves from the inner part of your ear canal to the entrance of the canal. Jaw movement also helps the earwax move through the canal.
Some things can cause problems with this normal process. Any type of blockage in the ear canal can cause a problem. Some people also may make too much earwax. This causes it to build up in the ear canal. The earwax may not totally block your ear canal. Most people have just a little buildup of earwax, which doesn't cause any symptoms at all.
Impacted earwax is very common. As you get older, earwax tends to become harder and less mobile. Older adults are more likely to have problems with too much earwax. It can cause symptoms, such as hearing loss. It can also prevent a full exam of the ear.
