Questions to ask during consult for brachioplasty & contouring?

I want to make the most out of my consults and I'm wondering what sorts of questions I should ask? I had my very 1st consult yesterday. I am just in the beginning stages of doing research to see if PS is worth the cost, pain, scarring, and potential complications. My surgeon's office has a PS connected with them, so I met with him yesterday and didn't have a lot of questions for him (I wish I would have posted this a few days ago). He explained to me what kind of results I could expect from a custom back contour (which I felt content with) but when he was explaining the potential results for the arm lift, I was less than satisfied. I'm doubtful that I'll have "skinny arms" post PS, because he said that if they cut all the excess off, they wouldn't be able to close that large of an opening. He also mentioned that their would be some loose skin hang at the elbow and at the armpit so my joints wouldn't be limited. He also mentioned that the scar would be quite large. Now I've looked at pics of many folks on here who've had an arm lift, and I completely understand the length of the scar. Is the scar that wide across? I don't recall seeing any hang at the elbow or armpit for "joint's sake" so I'm wondering if this is just how he does his work?

Anyhow, as I begin to locate other PS's in the area, I'd like to make my consults most useful, so your questions are appreciated!
