Earwax (cerumen) is produced by glands in the ear canal. Although scientists are still not completely sure why we have earwax, its purpose is to trap dust and other small particles and prevent them from reaching, and potentially damaging or infecting the eardrum. Normally, the wax dries up and falls out of the ear, along with any trapped dust or debris. Everyone makes ear wax, but the amount and type are genetically determined just like hair color or height. Smaller or oddly shaped ear canals may make it difficult for the naturally occurring wax to get out of the canal and lead to wax impactions.
Blockage, or impaction, occurs when the wax gets pushed deep within the ear canal. Earwax blockage affects about 6% of people and is one of the most common ear problems doctors see.
Symptoms of an earwax impaction include:
See your doctor if you think you may have any symptoms of an earwax impaction. Other conditions may cause these symptoms and it is important to be sure earwax is the culprit before trying any home remedies. Go to the hospital if:
A doctor can diagnose earwax blockage (or eardrum perforation) by listening to your symptoms and then looking into your ear with an otoscope (ear-scope).
Over-the-counter wax softening drops such as Debrox or Murine may be put into the affected ear and then allowed to drain out after about five minutes while holding the head to the side, allowing the drops to settle. Sitting up again will let the drops drain out by themselves. Sometimes OTC kits can lead to further impaction.A bulb-type syringe may be used to gently flush the ear with warm water. The water should be at body temperature to help prevent dizziness. Sometimes irrigation can lead to further impaction.Ear candling is not recommended. The procedure uses a hollow cone made of paraffin and beeswax with cloth on the tapered end. The tapered end is placed inside the ear, and an assistant lights the other end, while making sure your hair does not catch on fire. In theory, as the flame burns, a vacuum is created, which draws the wax out of the ear. Limited clinical trials, however, showed that no vacuum was created, and no wax was removed. Furthermore, this practice may result in serious injury.
The doctor may remove your earwax with a small plastic spoon called a curette, or use suction to pull wax out of your ear canal, or prescribe prescription-strength eardrops to soften and aid in removal.
Earwax blockage can be prevented by avoiding the use of cotton-tipped swabs or Q-tips and other objects that push the wax deeper into the ear canal.
