It is very important to communicate to your surgeon what you would like to look like after FFS. While most of us just describe what we want with words, bringing along a picture or two is perfectly fine, if it helps you communicate what you desire.
The surgeon will be to tell you what is possible and what is not. Keep in mind, FFS is an art, not a science. Some surgeons seem to have better results than others, but there is no way to predict exactly what you will look like after surgery.
