What should I look for most when reading jaw contouring reviews?

I'm looking up reviews for jaw contouring, but the scope of the surgery seems too extensive to just look at the changes in face shape.

I'm becoming more cautious because I've heard that occlusion and jaw function need to be considered as well.

When looking at reviews, is it more important to consider how detailed the analysis is during the consultation than just the before and after photos?

I've heard that swelling and recovery times vary from person to person, so I'm not sure how long I should expect them to be.

For those of you who chose a hospital based on reviews, what criteria did you use to compare them?
