Earwax is a waxy material produced by sebaceous glands inside the ear. It cleans, lubricates and protects the lining of the ear by trapping dirt and repelling water.
Earwax cause temporary hearing loss because it blocks your ear canal. Once the blockage is removed, your hearing will improve.
Some people are naturally more susceptible to developing a blockage in their ear, for various reasons.
Blockage, or impaction, also occurs when the wax gets pushed deep within the ear canal. Earwax blockage affects about 6% of people and is one of the most common ear problems doctors see.
Your risk of developing problems from a build-up of earwax is increased if you have:
• narrow ear canals or ear canals that aren’t fully formed
• a lot of hair in your ear canals
• bony growths in the outer part of your ear canal – these are called osetomata
• a skin condition of your scalp or preauricular area
• hard wax
• a history of recurrent impacted earwax
• repeated ear infections
