I wish I could be of help!
The word Otosclerosis caught my eye; I was diagnosed with it in the early 1970s; my father had it, his mother had it. Between us we’ve spent enough on hearing aids to cancel the national debt.
A word of caution. If a doctor proposes surgery, push for answers and percentages - always keeping in mind that the disease is degenerative and even if a new stainless steel stapes restores your hearing right after surgery, it will continue to be sclerosed and immobilized over time. Trying hard to be clear and objective here, and failing miserably; just be careful!
Batteries and tubing a cheap compared to hurt feelings of people you care about but cannot understand, and who can’t or won’t adjust their speech (speed, cadence, volume, precision) to provide you sufficient signal for you to assemble into intelligible speech. Be gentle with yourself, and with those who refuse to accommodate to your hearing deficit, or accuse you of ‘selective hearing’.
You may wish to treat communication as a game… there are blank spots (consonants, vowels, whole words) in what you pick up. If you interpolate enough to make sense of it, you won that round! If you guess wrong, find the humor in the difference between what was said and what you heard; laugh, and go on.
Also - large grain of salt - I’m (was) an Engineer, not a Doctor, so my 40-50 year-old information about middle ear surgery may be too out-of-date to be relevant.
Best of luck! The people here can be very supportive, check back and make friends.
