Hi tatianac!
I’m glad you’ve decided to move forward w/ surgery. I think it’s the right choice. I totally agree w/ what SewMomma said. Besides all that, the neck scars are nearly invisible once fully healed so you only get bragging rights for the first few months post op.
Here is one post by someone who had bilateral intraoral surgery. I believe there are others. If you click on the magnifying glass icon above & type in “bilateral intraoral surgery” all the posts that mention that will come up for you to read. The post was made by Catmd in Jan '18
