Well GB, I have been Deaf in my left ear for most of my adult life due to constant ear infections as a child. I've lived with it with out to much trouble. I had surgery on it about thirty years ago. It worked fine for about a year, then reverted back to where it was before. One advantage is in bed. If I lay on my right side, It drowns out all sounds, you know, The wifes snoring, the kids music, the road sounds.
Now, mine is not repairable anymore, but if it was, I think I would leave it as it is.
