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.
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:
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.
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.
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:
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 life longer.
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)
