Earwax, or cerumen, is secreted by special
glands in the wall of the outer
Ear canal. The glands are essentially modified sweat glands. The
wax they secrete, together with hair follicles in the canal, help to protect against foreign matter entering the ear. Usually the wax works its way out of the
canal on its own. In some persons, however, it tends to build up and harden. If unremoved, it can then cause some hearing loss. A person should not attempt to remove such wax balls, because damage to the eardrum or ear canal may result, but they are easily removed by a doctor.
