This is one of those things where I would say: NO.
Most MtF surgeries carry risks, but this one carries such a large risk, and is not inherant to ones physical nature, and you can get to the same place with proper therapy or self training.
This is not SRS,FFS or BA. This one can put you at an extreme disadvantage.
Wait 5-10 years, and maybe by then it will be perfected. They are testing a laser method in California right now (i think its a laser method?), which may be the way to change this in the future. It is designed to change the voice for MtF types, and is supposed to be significantly safer than the current procedure. In the next 3-5 years it may appear in some clinic as an outpatient proceedure, and trust me, when it comes around to being avaliable and no longer in the test phase, I will be the first girl to get it if I could. This is coming from somebody with a higher vocal range.
As it stands though, stay far away from the current proceedures.
