(Earwax, Ear Impaction, Ear Blockage)
Pronounced: suh-ROO-men im-PAK-shon
Definition
Cerumen is the soft yellow wax secreted by glands in your ear canal, more commonly known as earwax. Cerumen impaction occurs when earwax becomes wedged in (impacted) and blocks the ear canal.
Cerumen or earwax has many useful purposes. One of the main uses is that it protects against infection. It helps fight bacterial ear infections and protects the inside of your ear.
Earwax moves out of your ear naturally. Earwax should not be removed by you from your ear. In fact, continuously trying to clean your ear of cerumen by using a cotton swab for example can damage your ear. By trying to remove earwax, you can:
• Damage your eardrum (the membrane that vibrates and transmits sound to the middle ear)
• Make yourself more prone to ear infections
• Make yourself more prone to swimmer’s ear (an infection of the skin that lines the ear canal)
• Injure the ear canal
• May cause the cerumen to become more impacted and more difficult to remove
The Ear Canal
It is important to prevent cerumen impaction before it happens because it has been found to cause hearing loss.
This condition can be treated; contact your doctor if you think you may have cerumen impaction.
Causes
Cerumen impaction is usually caused by inability of the ear to naturally clear itself, and unsuccessful attempts to remove earwax. By inserting a cotton-tipped swab into your ear, you actually jam the more solid part of the earwax deeper into your ear. Your ear has a harder time trying to get rid of this harder, bulkier wax, and the impaction or blockage begins.
Factors that contribute to cerumen impaction include:
• Trying to remove cerumen with a cotton-tipped swab
• Putting objects into your ears that may push the cerumen in the ear canal deeper
Risk Factors
A risk factor is something that increases your chance of getting a disease or condition.
The following factors increase your chance of developing cerumen impaction:
• Individuals who obsessively try to clean their ears and try to remove the wax
• A twisted, narrow, or complicated ear canal
• Ears that overproduce cerumen
• Age: affects the elderly and causes hearing loss
• Mental retardation
Symptoms
If you experience any of these symptoms, do not assume it is due to cerumen impaction. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.
Symptoms include:
• Itching of the ear
• Pain in the ear
• Tinnitus (ringing) in the ear
• Hearing loss
Diagnosis
Your doctor will ask about your symptoms and medical history, and perform a physical exam. When you go to your doctor, he or she will look into your ear with a special flashlight called an otoscope. Your doctor will look for impacted earwax.
Treatment
Treatment involves removal of the earwax from the ear canal. Talk with your doctor about the best treatment plan for you. Treatment options include the following:
Removal of Cerumen by an Instrument
Your doctor can remove cerumen using one of several instruments, including:
• Curette–a surgical instrument shaped like a scoop
• Suction–when the cerumen is loosened, the doctor will vacuum the earwax
Removal of Cerumen by Flushing
Your doctor may rinse the impacted cerumen using flushing equipment.
Ceruminolytic Agents
Your doctor may prescribe or recommend using a ceruminolytic agent. This is a liquid-like solution that is used to drop into the ear and soften the earwax to help ease removal.
Prevention
To help reduce your chances of getting cerumen impaction, take the following steps:
• Do not clean your ears with anything more than a soapy washcloth on the outer rim of your ear.
• Do not use cotton-tipped swabs to clean anywhere inside your ears.
• If you are concerned about earwax, see your doctor and do not attempt to remove the earwax by yoursel
