Ear Wax Removal in Tyne and Wear

  • What Is Ear Wax?

    Ear wax or Cerumen is a natural yellow/brown substance that is secreted by sebaceous glands in the skin lining the ear canal. Cerumen can be soft or hard, wet or dry. The type of wax you have is genetically inherited.

    Why Do We Have It?

    It is believed that ear wax serves several purposes

    • It acts to clean the ear canal, traps debris and dust also dead skin cells. Ear wax also traps small foreign bodies (insects etc).
    • Ear wax acts as a lubricant for the skin of the ear canal, preventing it from drying out and cracking.
    • It acts to protect the ear canal and eardrum. Due to its Ph being slightly acidic and the antibacterial properties it possesses, ear wax reduces the risk of fungi and bacterial ear infections.

    How Does It Work?

    In most people, ear wax will naturally migrate outwards to the entrance of the ear canal where along with any debris, it will fall out.  The layer of skin in the ear is remarkable in that it not only secretes the wax but it has the unique property of moving sideways towards the entrance to the ear canal as it grows and sheds.  Ear wax does not normally cause people too many issues, but in some cases ear wax can build-up and become impacted and uncomfortable.

  • What Causes Ear Wax Build-up?

    Everybody produces ear wax however some of us produce more than others, Some produce excessive amounts of wax overwhelming ther natural migration of the wax.  Other reasons can be:

    • Wearing hearing aids or ear plugs can block the normal path of the wax.
    • Excessive hairs in the ear canal can trap the ear wax and block the normal path of the wax
    • Very narrow ear canals can cause the wax to become impacted.
    • Using cotton buds or other items to clean the ear can push the wax further into the ear canal causing to become impacted.
    • Very dry and hard ear wax which makes it hard to migrate out of the ear (more common with age).
    • The Ear canal has Exostosis (Bony protrusions)  blocking the wax in and causing it to build up.
    • Abnormalities to the layer of skin lining the ear which mean it does not migrate sideways as it grows and sheds.
  • What Symptoms May I Have?
    Blocked Ear

    Most people get a “blocked up” sensation or a feeling of “fullness”. This is caused by the wax acting like a plug in your ear.  Other symptoms of wax can be:

    • A feeling of fullness or dullness
    • Temporary hearing loss
    • Internal sounds (when you chew or breath your own voice seeming to be loud in your head)
    • Tinnitus a ringing in the ears.
    • Earache (otalgia)
    • Very itchy or irritated ear canal
    • If you wear hearing aids constant whistling from your aid.
    • You may feel light-headed (vertigo) this is an area under investigation.
    • A tickly cough this can be caused by the wax build up putting pressure on or stimulating the facial nerve inside the middle ear.
  • What Methods Are Available to Remove a Build Up of Ear Wax?

    There are four common methods of treatment used in the removal of ear wax. These are ear wax drops, ear syringing or irrigation, micro-suction ear wax removal and endoscopic ear wax removal.

    Ear Wax Drops

    There are many over the counter preparations available from any pharmacy to loosen, soften or dissolve ear wax. These will be either oil-based (olive oil) or water-based (sodium bicarbonate or saline).  Water-based drops are considered to be more effective at dissolving ear wax than oil-based preparations. If a perforation has been diagnosed in the past, drops should be avoided, as they may cause issues with middle ear infections.  The drops are applied at home and must be at room temperature to avoid the “caloric effect”, which is caused when the balance organ in the ears are out of sync. This is due to an inhibition in its function caused by the cooler air or water.

    The application of ear wax drops can be messy and time-consuming. It requires the affected ear to be facing upwards when the drops are applied. Once applied, you must remain there for 5 to 10 minutes after which, you can sit up and wipe away any excess which will come out of the ear.  This process needs to be applied 2/3 times per day for 10 to 14 days.  Even after this procedure if the wax is impacted the use of drops alone may not be successful.

    Ear Syringing (Irrigation)

    Ear irrigation is normally performed by a GP practice nurse, a district nurse, and by some Audiologists. It is usually free on the NHS. Traditionally, a metal ear syringe was loaded with warm water, the metal tip placed into the ear canal. The water was then squirted into the ear canal and a kidney dish was held under the ear to catch the water and wax that was flushed out. The syringe would have to be regularly lubricated to allow a smooth level of pressure to be applied. The nurse would use his or her judgment as to how forcefully to syringe the water. Nowadays, for safety reasons, the metal ear syringe has been replaced by an ear irrigator pump with a jet tip. The pump has a variable, regulated pressure, but the process is essentially the same. Many people have had their ears syringed or irrigated many times without any issue arising.
    Side Effects, Risks and Disadvantages

    When it works it works well, however, ear syringing comes with some risks and disadvantages:

    • Hard wax must be softened for up to two weeks before syringing.
    • Syringing can push wax further into the ear if the angle of the jet is slightly off.
    • May cause tinnitus.
    • It may perforate the eardrum.
    • An undiagnosed perforated eardrum may not be seen due to the amount of wax. This will cause water, bacteria, wax and dead skin cells will be flushed into the middle ear. This could potentially cause a painful infection.
    • Is not recommended following ear surgery.
    • Should not be performed when the eardrum has previously been perforated due to the risk of re-perforation.
    • Ear syringing should under no circumstances be performed on individuals with a known perforation, cleft palate, foreign object in the ear canal or a mastoid cavity following a mastoidectomy.
    • Many surgeries are withdrawing their ear syringing service and are referring all patients to the NHS ENT clinic. The
    • NHS ENT clinic may have a long waiting list.

    Micro-Suction Ear Wax Removal

    Micro-Suction Ear Wax Removal

    Micro-suction is normally performed in hospital outpatient clinics by ENT doctors and nurses when other methods have not been unsuccessful.  The major benefit of micro-suction is that the wax is removed safely under direct vision at all times. In a hospital, the procedure is undertaken using an ENT binocular microscope to clearly visualize the wax. A sterile suction probe connected to a gentle suction machine is then used. Other ENT instruments can also be used.  Unlike irrigation or syringing micro-suction is a “dry” procedure and does not require the use of water. This significantly reduces the risk of damage to the eardrum and an infection.

    How Does it Work?

    The use of micro-suction is quicker and safer and does not require weeks of ear drops. Micro-suction in ENT departments is performed using large expensive ENT binocular operating microscopes. Due to waiting lists many people have to wait weeks or months for an appointment.  DSome Hearing aid audiologists are now trained to offer micro-suction but they use microscope ‘loupes’. These look like specs with a headlight and are readily available and affordable. They are however, not as effective and safe to use when compared to ENT microscopes.

    Side Effects and Risks

    Due to the suction machine, this process can occasionally be noisy due to the suction machine. Sometimes flaps of dry skin vibrate causing ‘clareneting’. Subsequently like ear syringing people report tinnitus or increased tinnitus if they already experience it before micro-suction. There is also a slight chance of bleeding due to grazing or scratching the ear canal with the suction probe.  Secondary trauma of the eardrum caused by the suction probe and other ENT instruments is also possible but very rare.  The caloric effect can be experienced in micro-suction due to the cooling effect of the suction probe. This can make the patient feel a little dizzy but passes in a few minutes when temperatures stabilize.  

    Endoscopic Ear Wax Removal

    Clearing Ear Wax

    An alternative to micro-suction is endoscopic ear wax removal,  it is quicker and easier to perform than micro-suction.  To perform endoscopic ear wax removal an oto-endoscope is used. This a more advanced medical ear torch than the conventional otoscope used by audiologists and doctors to inspect the ear. It is a rigid small diameter fibreoptic telescope to provide an incomparable ‘wide’ and high-resolution view of the ear canal. This makes it both comfortable and safe since it allows it to be rested in the ear canal and allows visualization of the whole ear canal and eardrum with minimum manipulation of the patients head.  The other hand use the suction probe to gently remove the wax or to use other ENT instruments as required.

    2010 Health Technology Assessment by AJ Clegg et. al. concluded that endoscopic ear wax removal is superior to microscopic wax removal – microscopic wax removal uses an operating microscope or surgical loupes to get a magnified view of the ear canal and ear drum – a speculum (small funnel) must be inserted into the ear canal in order to provide a view, and the speculum takes up some of the space within the ear canal, further restricting the practitioner’s view. Furthermore, the speculum can sometimes cause minor trauma to the skin of the ear canal if the ear canal is very narrow.

    How Does it Work?

    In contrast, endoscopic ear wax removal uses a fine 2.8mm endoscope inserted part way into the ear canal. The endoscope is a rod containing fiber-optics to relay light from a light source to illuminate the canal and a solid lens (or series of lenses) to relay the view from inside the canal to the outside. The endoscope can be either viewed directly, or imaging equipment can be attached to provide better magnification

    Side Effects and Risks

    As with micro-suction, endoscopic ear wax removal can be noisy. There is a very small risk, as with all other wax removal treatments, that some people may report tinnitus or increased tinnitus if they already experienced it pre- ear wax removal. There is a small chance of slight bleeding due to grazing and scratching the ear canal with the suction probe. However, compared to micro-suction, this risk is further reduced because there is more operating space available.  Secondary trauma of the eardrum caused through the oto-endoscope, suction probe and other ENT instruments is also albeit rare.  As with micro-suction the ‘caloric effect’ is possible due to the cooled air currents created by the suction machine, this may cause a temporary dizzy feeling which passes after a few minutes.
