OTOSCLEROSIS
Presented by:

INTRODUCTION
Otosclerosis is a common cause of hearing loss. It is caused by a problem
with the tiny bones (ossicles) which transmit vibrations through the middle
ear so we can hear sound. Usually both ears are affected in otosclerosis but
sometimes only one ear is affected.
DEFINITION:
Otosclerosis is caused by an abnormal growth of bone in the ears, which causes
hearing loss. In its early stages, the sufferer will normally not be affected. In most
cases, a surgical operation will restore the hearing
