I can't speak to TW's particular case, but yes, there are surgical approaches that help you retain your hearing. Mid-fossa is the approach with the biggest chance, followed by retrosigmoid and translab.
As for being SSD, one of the biggest issues IMO is lack of directionality. You can hear something, but have no idea where it's coming from. For example, if you are standing in a bank of elevators, you'll hear one "ding" to tell you it's coming, but you'll have to spin around in circles and look at the lights to see which one it is
Another issue is someone talking on your deaf side. You can't hear them. You get to the point where you try to position your body so that people are on your "good" side by either picking the "best" spot at the table or by constantly turning your body so your good ear is the one they are speaking into.
Holding a phone to your deaf ear is pointless. Hearing in noisy and crowded rooms isn't workable either.
Everyone adjusts to being SSD differently. Honestly, there are those who adapt just fine and don't have any issues they can't deal with. Then there are those like me who "go down kicking and screaming" - as in I hated being SSD and found it very depressing. The day I did the BAHA demo I realized that a majority of my SSD issues would be solved - and my depression basically flew right out the door.
Aids and implants aren't for everyone, but some of us couldn't exist without them.
