Yes, Robyne's idea of doing a short scar arm lift is the closest you can get. From what I've heard this way only works on milder cases, and won't be much help if there's a great deal of skin and flab closer to the elbows. How bad would you say yours are?
I think we're a long ways off from having scarless arm lifts. Even if they cut out the flab laparoscopically you would still be left with the extra skin, so I don't know if an armlift with a scar will ever be possible, or at least not until they find a way to make scars disappear.
