For those that got FC/V Line.. pros and cons?

For those that got such surgeries, and anything similar to any type of FC, could you please comment on the post-surgery results and if you have noticed anything different since the surgery? Like no sensation or feeling.. can't move your jaw a certain way.. etc. Looking for both pros and cons but mainly focusing on the risk side of things so I can make an informed decision to see if it's worth it for me.
I am not scared of any surgery (got rhino, eyes, and BA) but for some reason, FC scares...
