Thank you very much for your answer Kendra.
My main issue to be worried about is the healing process. Before the surgery I've already had a 200+ Hz voice (but it costed me many efforts sustaining that pitch constantly. It's the result of more than 10 years of practice). I'm sorry because I won't be able to provide you with as many details as you may need to determinate wether if I would have a success in this or not... (Most of everything because of privacy, I can't provide a lot of details about of my Medical History).
But yeah, the main issue which kept me worried was the fluctuation between clear voice/rough voice/no voice... But I think it makes sense because of the botox injections' effect. So if I try to use my vocal folds, as they have been paralyzed by these injections, it would be harder for me, just to produce any kind of sound.
Leaving aside that matter, I'm keeping as much silence as possible. As Dr. Kim said.
But as a conclusion: Would you say Yeson provides over all successful results (taking into account that you're supposed to follow their instructions) ?
I'm aware about I can't expect anything until the 4th to 6th month has passed... Yet, I don't know if I would be forced (or if anyone could be forced) to take a 2nd procedure with Yeson, because of the failure of the 1st one. (Once again, taking into account you've followed everything).
It's a very weird sensation, because, as you said, a phonatory system is very complex, so I don't know which % of success or failure is present, under which conditions and how to feel "safe" testing anything regarding my voice...
But yeah, my main issue was the pitch & voice fluctuations during the 2nd month. I understand as soon as the 3rd month starts, I should have, at some point, voice enough to undertake Voice rehabilitation exercises, but right now I'm even unable to produce any sound, depending on the day.
PS: If my age is something to take into account, I am 30 y.o. I don't know how this could affect the result. I've been on HRT since I was 18 y.o
