Can I combine TT, BBL via fat transfer, inner thigh lift, and BA?

Hello dear!
Thanks for the question and provided information as well.
Depending on your health, these surgeries can be done at the same time, but I recommend my patients to do it in two sessions, due to recovery and the time under anesthesia.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

You are asking for too many procedures at one time. I would start off by doing your fat transfer and gluteal shaping. The next surgery I would do would be your breast augmentation tummy tuck. The last surgery I would do would be the thigh lift. Earl Stephenson, JR, M.D., DDS, FACS 

It has been shown that surgeries can be combined and done at the same time safely. It is recommended that the total time in the operating room not exceed 6 hours in an outpatient setting. It may be possible that a tummy tuck, breast augmentation and BBL be done at the same time as they can be likely be accomplished in less than 6 hours. Adding the thigh lift is definitely pushing it, especially if there is only one surgeon operating. However, in my opinion, the best results come with staging the procedures. I like to do the BBL first, as I can liposuction your entire trunk and harvest the maximal amount of fat possible to transfer. Many times that transfer of fat includes some fat to the sides or the hips and buttocks area. So I ask my patients not to sit and to sleep on their bellies for at least two weeks to maximize fat graft survival. You do not want that pressure on your buttocks for the first couple of weeks after the fat transfer to maximize fat graft survival rate. When you do a tummy tuck you will be sitting and sleeping on your back in a flexed position which puts pressure on your buttocks. So to answer your question, it is highly unlikely that all 4 procedures can be done well within 6 hours total anesthesia time by one surgeon.  I suggest you do the BBL and medial thigh lift first followed by the tummy tuck and breast augmentation a few weeks to a couple months later as these have the best post op positioning combinations.  Hope this helps and best of luck.
