Ear
Care and Injury Prevention
October 2002
Part of your daily cleanliness routine
should be careful cleaning of the outer part of the ear (pinna) to
remove wax secreted by glands in the ear canal. Wipe a clean, damp
washcloth around the outside contours of the ear as well as behind it.
Never try to reach the wax in the invisible, deeper part of the ear with
a cotton swab or a finger; you could push the wax deeper into the ear
canal. Once this has happened, the wax, which usually moves along the
canal to the outside and flakes off, hardens to a dark orange lump that
irritates the wall of the ear canal and causes the skin to peel. The
build-up can completely cover the eardrum and cause temporary deafness.
The plug then has to be removed by a physician.
Wax also tends to trap water in the canal
after swimming or washing the hair. This may cause temporary deafness.
Tip your head to one side and gently pull the external ear forward. The
water can then flow out of the ear.
Ear Care: Infections
Ear infections need prompt medical
treatment. Whenever you have an acute earache, consult your physician.
Infection can enter the ear when you are
swimming or diving, particularly in hot climates. It is a sensible
precaution to wear earplugs when swimming. A boil in the ear canal is
extremely painful because the surrounding tissues are tight. Never
squeeze the boil, but see a physician immediately.
Ear Care: Nose Blowing
An infection of either the nose or the
throat can easily reach the ear and cause a painful infection of the
middle ear (otitis media). The chance of the infection spreading can be
reduced by carefully blowing the nose. If the nose is blown violently,
mucus can move up the Eustachian tube to the middle ear. Blow your nose
gently, and make sure the nostrils are open before you begin to blow.
Ear Care: Protection From Injury
The eardrum is vulnerable to many kinds of
injury that can result in partial or even total deafness. Never strike
an adult or child across the ear; this can force air down the canal and
burst the drum.
The ear can also be injured by high levels
of noise. Loudness is measured in decibels. Exposure to noise at a level
of more than 85 decibels causes temporary impairment of hearing.
Continued exposure causes increasing, irreversible deafness. The first
symptom of noise damage is a buzzing or ringing in the ears when the
noise stops. The buzzing may take days to subside. This can happen in
discothèques, if you are part of a band, or if you work in noisy
surroundings.
Because of these dangers, if you work
around high-level noise - for example, jet engine maintenance - you must
protect your hearing with plugs or ear guards.
If you have a perforated eardrum, do not
allow water or other foreign materials to enter the ear canal. Use
airtight earplugs for bathing. Do not use eardrops unless prescribed by
a physician.
