A hereditary disorder, otosclerosis is characterized by progressive deafness caused as a result of the abnormal growth of bone in the inner ear. With the root cause remaining to be ascertained, experts are of the opinion that the condition may be due to problems with the immunity, stress fractures or a problem of measles infection in the past. The abnormal development of bone in the middle ear prevents ear bones from making the appropriate response to sound waves. The condition typically begins in early adulthood or mid-adulthood with women more prone to it than men. Loss of hearing ability is a very common consequence of this condition.
