Dear Jenny,
thanks for posting your before/afters. As far as I can see, this is VERY good work by Dr. Kim. And please note that the large "V" only exists with the vocal folds in the breathing position, so you don't have anything to worry about. In phonation position, the folds touch along the midline. And the "V" we've been talking about is far smaller: just the little contact point of the newly formed commissure (where the green and blue lines would touch in your picture). If the procedure caused scarring, there wouldn't be a neat contact point, but more or less of a gap through which excess air would escape without contributing to phonation.
BTW, I just got off the phone with a Stuttgart patient (a decade postop with Drs. Hagen/Miethe). She sounded very convincingly feminine to my ears, although her voice was a tad duller sounding than yours that has this wonderful mezzo ring to it. But this could be because of being inexperienced in voice technique. But the main outcome of this conversation was to provide a frame of reference for the long-term effect of this surgery: it's indeed absolutely permanent, her voice reportedly hasn't changed since, which I'm more than ready to believe. She mentioned that she lost some volume with the surgery, though. Jenny, can you fill us in how volume develops after a Yeson surgery?
Plus, I heard that Gross is no longer doing most of the Berlin surgeries, apparently a colleague of his, Dr. Nawka is. Hearsay has it he's also good. But that's for me to find out in February. I wrote to them again if they could provide me with samples in advance of our meeting. Let's see how they react.
Bottom line: Kim still remains top choice for me, although sound-wise Stuttgart appears to be a viable option for people unwilling to make the trip to Korea.
Best wishes, happy holidays to all,
Amy
