Brazilian Butt lift for an MTF transgender patient? (Photo)

If you have fat, then a BBl can be performed. If not, buttock augmentation with implants is possible. Best of luck!

Thank you for your question. I would strongly recommend and urge you to please NOT get silicone injections for buttock augmentation. People can have serious complications from that procedure and it is something that most board certified plastic surgeons would not recommend. Often silicone and oil and other injections are not done under safe and sterile conditions leading to very bad infections and serious and possibly life threatening complications. 
To answer your questions though, yes, BBLs can certainly be performed on transgender patients if they are otherwise good candidates for the procedure. As you may know BBLs involve liposuction, purification, and transfer of the fat from one area (typically the abdomen, waist, etc...) to the buttocks. It is hard to tell from your photos but you may be a good candidate.
Please see a Board Certified Plastic Surgeon to discuss your options in person.
I hope this helps!
