Specialised glands known as cerumen glands actively create ear wax deep under the skin of the ear canal. Connected to the glands are the
cerumen ducts which allow the ear wax to travel to the surface of the skin to be deposited in the ear canal via the numerous cerumen pores.
Earwax plays a very important part in protecting our ears on a daily basis by reacting to foreign bodies and surrounding them. Once enveloped the captured
microbial organisms, dead skin cells and various other debris is removed from the ear canal by the earwax migrating outwards.
So we know that earwax is a normal and necessary process of protecting our ears, it repels insects, maintains normal PH levels and traps dirt and dust from the environment.
But what to do when we develop too much earwax?
If left untreated the earwax can continue to build up, making it even more difficult to remove and leaving your ears feeling blocked and reducing your hearing.
In some cases the blockage can be so severe that people are left feeling constant pressure and pain.
Here are some typical indicators of earwax build up:
Loss of hearing
Tinnitus...noises in the ear
Constant or intermittent whistle from hearing aids
Your own voice sounds deeper and hollow to yourself
Earwax is the number one cause of a whistling hearing aid
Earwax can be particularly bothersome for people with hearing aids because it can cause hearing aids to whistle loudly and uncontrollably
or even prevent the hearing aids from working at all. The pictures on the left compare an ear canal full of earwax with a clear ear canal so that
sound can travel without obstruction to the eardrum.
The whistling will only stop once the earwax is removed so that the sounds produced by the hearing aids can travel efficiently through the ear
canal and no more whistling will occur.
Avoid cleaning your earwax yourself!
If you have the widespread habit of thoroughly cleaning your ears by putting in them plastic buds wrapped around the edges with cotton,
just stop doing it - this is the latest advice from the Otolaryngology academies, which study the diseases of the throat and ears. They have even published
guidelines for ear care, with emphasis being placed on preventing excessive "do it yourself cleansing" of the ears and especially the intrusion of various
cleaning items into the ears. The truth is that by pushing cotton sticks inwards; you risk pushing the excess wax inward rather than pulling it out, causing
health problems with your ears.
The benefits of Earwax
If you have very little wax in the ear canal, your ears start to feel dry and itchy. However, the correct amount of wax helps in a few ways:
Prevents dust, bacteria and other germs from entering and damaging the ear
Catches dust and slow-growing bacteria
Protects the skin of the ear canal from irritation by water
Your ears should have a healthy amount of wax, since they are a part of the body that cleans itself. The excess wax automatically exits the atrial channel,
since there the cells migrate naturally. The removal of the wax is also aided by the movements of the jaw (when talking, chewing, etc.) and, once it reaches
the outside of the ear, it will simply fall or be eliminated when taking a shower or a bath. However some of us gradually build up earwax over the years and
need a specialist to help us clean the excess. It is important to get your ears checked annually as, like with teeth, they need extra care to help us enjoy
Micro Suction Ear Wax Removal
Micro-suction is by far the most effective method of earwax removal. Traditionally only performed in ENT clinics due
to the size and weight of the equipment, it can now be performed by appropriately trained individuals in smaller clinics due to
portable suction pumps and operating microscopes that are now available. Micro suction is made up of two words: “Micro” refers to
the operating microscopes that can either be large floor standing units, or can be incorporated into glasses, in which case they
are known as operating loupes. “Suction” refers to the medical suction pump that is attached to a tube and a 2 millimetre suction wand,
which is used to suction the wax from your ear.
Micro suction requires a good knowledge of the anatomy of the ear, along with training in how to safely use the equipment. For this reason,
micro-suction is performed by Audiologists, who specialise in the ear, and by specialist nurses who have had further training. Micro suction
only removes wax from the ear – because it doesn’t spray water into the ear it is safe to use after ear surgery, or when the eardrum is
perforated. The Micro Suction Practitioner uses a powerful operating microscope and a bright light source, so he or she can see exactly
what is happening inside your ear, so the procedure is the safest of all.
Pros: safest method; can be used after ear surgery; can be used where the eardrum is or has been perforated; painless; virtually no risk of
infection; usually quick
Cons: possible slight discomfort if wax hasn’t been pre-softened; can sometimes require a second visit (in the case of severly impacted wax);
some people find it a little noisy (although clinical studies show that the noise levels are safe)
