The problem with your post is Otosclerosis affects some people faster than others and with others it comes on slowly, so what your going to get is data that basically shows that with some people it came on very suddenly and with others it took years to develop. In the U.S. only .5% of the population develop Otosclerosis during their lifetime, yet post mortem studies have shown that 10% of the people had Otosclerosis like lesions yet never had symptoms of the disease, so for a vast number of people with the disease they are asymptomatic.
I would take Um Bongo’s suggestion of going to someone who specializes in Otosclerosis and get their input into how to best manage your disease if it is indeed Otosclerosis.
