A perforated eardrum can be prevented by avoiding insertion of any object into the ear to clean it or to remove earwax (cerumen).
Glands within the skin of the canal produce a waxy substance called cerumen (popularly called earwax).
Less common causes of cerumen impaction include overproduction of earwax by the glands in the ear canal or an abnormally narrow ear canal that tends to trap the wax.
Impaction-A condition in which earwax has become tightly packed in the outer ear to the point that the external ear canal is blocked.
Think about inventing a flexible yet discrete device for decisively removing earwax.
