Hello from VT. USA.
exactly two months ago i had the canal wall up procedure. the malleus and incus (hammer and anvil) bones
were removed. the tip of the hammer was salvaged and placed on the new ear drum in combination with
a micron II titanium prosthesis. in English this means the surgeon linked my inner ear from the stirrup to my ear drum again.
the highest frequencies for me are harder to hear. if i plug my good ear and listen to a fan across the room i'll hear the motor or some fan sound but not the air swishing. the 'top' of the S's are harder to hear.
one thing i can tell you is for two weeks following the surgery i was stone deaf in that ear due to the ear canal being stuffed like a sausage with antibiotic paste and Gauze. they do that so the ear canal retains it's shape and doesn't heal itself shut. having one ear only is different because EVERY sound is seemingly coming from one side. you have no directional capability. that is frustrating. you'll find yourself doing the Stevie Wonder moving your head back and forth to locate sounds.
If you can hear well enough now to get back in the military then get back in first.
cholesteatoma's must be dealt with through surgery but it won't engulf your facial nerve in a couple of months so you have some time on your side.
everyone is different. my surgeon., Dr. Mark Levenson, Saratoga Springs NY, has been in this business for over 30 years. Also I'd find a way to determine what hearing levels are acceptable or waiverable in the military as there are a LOT of ear injured soldiers these days and many are still in.
Good luck. if you want to write, firstname.lastname@example.org and I'll be happy to answer anything else if
I can. so far so good. my ear is very much still healing inside. the outer incision is barely noticeable as it was done on the crease of where my ear meets my head.
can't look back but hoping for a bit more of the high end stuff to come back alittle more.
