Introduction • Ear Wax (Cerumen) is a natural protective oily substance which is produced in the outer third of the ear canal • Its function is to remove small foreign particles, such as dust, from the canal • This is achieved by the ciliary hairs.
Symptoms • Diminished hearing • often of sudden onset after “cleaning” the ears • Discomfort • seldom complain of pain unless the wax is pressing on the drum • Tinnitus occasionally
Educational Points • Wax is a normal physiological substance which has an important role in protecting the ear canal • The ear canal is a self-cleaning system, do not to use cotton buds as wax is more likely to be pushed back against the eardrum and become impacted. • Ear wax only needs to be removed if it causes symptoms or if a proper view of the eardrum is needed.
Self Care • Assess if: • Child • Pain • Discharge from the ear • Known perforation of the eardrum • Previous mastoid surgery
Self Care • Ear drops to soften ear wax (ceruminolytics) may be used as the only treatment in mild cases. • There are many different preparations on the market, none with any clear clinical advantage compared to the others. • There is some suggestion that sodium bicarbonate may be particularly effective at disintegrating ear wax. • A simple home remedy is olive oil, warmed by pouring onto a warm spoon. • Preparations containing organic solvents are particularly likely to cause irritation and inflammation of the external ear canal and should be avoided.
Primary Care Treatment • In more severe cases use of a ceruminolytic ear drop for 4 to 5 days prior to syringing is advisable • Removal with wax hook is also an option
Ear Syringing • Ear syringing has been shown to improve hearing in those with impacted wax • The lowest pressure possible should be used. • It is best avoided if • the eardrum is known or suspected to be perforated • there is a history of mastoid surgery or chronic middle ear disease • If patient has unilateral deafness • A history of recurrent otitis externa or tinnitus
