Hearing disorders Hearing disorders Conduction impairment and nerve impairment are the two basic categories of hearing problems. Nerve impairment results from insensitivity to sound because of inherited or acquired nerve damage. In this article I will define a few of the hearing disorders that will contribute to both of these categories. Mastoiditis is caused by infections that rupture the ear drum and spread to the mastoid cells. Ear trouble occurs because of infections of the nose, throat and Eustachian tube.
Germs can spread through the Eustachian tube into the middle ear due to being ill.
Causes of these infections can include an inflamed adenoid, bad colds, sore throat, or sinus trouble. Most damage to the end occurs in the middle ear. The middle ear carries most of the sound-conducting mechanism that may be destroyed by serious chronic infection. There are medicines that help to cure ear infections. In some middle ear infections, a doctor may make a small incision in the eardrum to reduce the pressure and pain in the ear.
