Hi,
Please don’t take this the wrong way, but what you’re asking is unlikely to yield an answer that helps you.
Otosclerosis is not typically illustrated by your loss: more often hearing losses present with a characteristic 2Khz dip (Carharts Notch). You mentioned in the other thread that you have a mixed low frequency conductive and high frequency sensorineural loss. This might be down to tympanic membrane issue, ossicular chain deformity or could be some form of stapes fixation or just two other underlying coincident conditions.
Asking for progression of otosclerosis, is unlikely to be beneficial if that’s not what you have. I’d suggest that you seek the advice of another professional to get a more positive diagnosis: ideally a specialist in the field.
As for Otosclerosis, it’s dependent on lots of factors, including the condition of the pathology, your genetic predisposition to the disorder, disease and possibly to some extent factors like diet, age and lifestyle. Collective data wouldn’t be entirely meaningless, but it would only serve to tell actual victims of the condition whether their progression was average, below or above.
