Cerumen (ear wax) Removal
done by irrigation. irrigation is contraindicated in pts with tympanic membrane perforation or otitis media. glycerin hydrogen peroxide, or mineral oil is placed in ear at bed time to soften wax. MAXIMUM AMOUNT OF SOLUTION USED FOR IRRIGATION IS 50-70 ML! never use ear candles
86
Foreign Object Removal From Ear
vegetables expand with hydration so irrigate with caution. insects are killed before removal unless they can be coaxed out by a flashlight or noise. lidocaine is used for pain. mineral oil or diluted alcohol is instilled to suffocate insect then is removed with foreceps. use small ear forceps to remove object avoid pushing object father into canal.
