Earwax (also spelled ear wax), medically referred to as cerumen, is produced by glands in the outer ear canal. Its purpose is to trap dust and other small particles and prevent them from reaching and potentially damaging the eardrum. Earwax may also prevent the growth of bacteria and fungi in the ear canal.
Blockage, or impaction of earwax occurs when the wax gets pushed deep within the ear canal. Earwax blockage affects about 6% of people and is the most common ear problem doctors see.
