Tummy Tuck 360 with fleur-de-Liz and breast lift with silicone implants, can it be done at the same time ?(photos)

I would Definitely stage this procedure.  I would perform the anterior work with the breast lift and possibly implants and the extended tummy tuck (extend the incisions as far as possible)  I would then do the back about a month later.  Safer and better results.

Congratulations on your successful weight loss! Generally speaking, combination surgical procedures are done routinely. However, you are wise in being concerned about the safety of combination surgery; risks/possible complications do increase with increased length of surgery… 
In my opinion, the combination procedures you are considering would be too much to perform in  a single session; I would suggest that you stage the procedures you are considering.
It is best to evaluate each patient's suitability for combination surgery on an individualized basis. During this consultation process, after a complete history and physical, the SAFETY of combining these surgical procedures becomes of paramount importance. Plastic surgeon, anesthesia provider, duration of surgery, surgery facility all important considerations.
Your best bet: choose your plastic surgeon very carefully; everything else including good judgment/advice/planning, anesthesia provider and safe surgery facility will follow.  Always keep priorities (safety,  avoidance of complications, and quality of outcome) in mind as you make your decisions.  Best wishes.
