Women have a larynx, too 😉 - So basically only the additional part of the larynx has to be removed, right? And if done properly you can still have a prominent larynx, but its not an adamy apple then, its just a larynx, a voice box - every human has one (almost).
I wonder though why Yeson does not provide the surgery. I know that some time ago, Dr Kims aid not to do a trach shave with anyone else because it can be bad for the voice, but I remember that he basically said to better do it with him, as he would know how to handle the combination. Another surgery team that can deal with it is FacialTeam in Marbella, they do FFS and also trach shaves and they know Dr Kim and can use proper intubation that is not harmful after a VFS and AFAIK they also know how to do a trach shave that does not impact Dr Kims voice work.
