I believe I've seen her mentioned on these forums before. It's an interesting idea, using a filler, but I'd have a couple concerns. One would be whether the surgeon has less control relying on a filler to hold the vocal folds together, as I'd imagine there's more precision involved with sutures than with substances that can spread throughout tissue. The second would be the fact that it sounds like she aims carte blanche for 40-50% reduction; any of the existing surgeons can go that high, but the fact that it pushes the upper limit of what can be done without ruining the voice would raise concerns about my first point regarding how much control exists with fillers vs sutures. There are also people who don't need quite so much reduction and would risk sounding unnatural with that much, so there's the question of whether her technique works at lower percent reductions.
Certainly a nice option for anyone who can get her services through the Canadian plan, though anyone with easy access to Toronto would already be within a couple hours' drive of Dr. Haben in Rochester anyway. I saw him in recent months and he did really nice work, it was a breeze.
