Hearing Loss

This is a loss caused by a problem in the outer or middle ear. It is called “conductive” because something is blocking the movement – or conduction – of sound into the ear. The canal can be blocked by earwax, infection, a tumor, or a foreign object. The eardrum can be damaged by injury or infection. In the middle ear, abnormal bone growth, infection or tumors can block the sound. Most conductive hearing losses are medically or surgically treatable.
