I personally wasn't interested in services of dr. Brassard (or dr. Chettawut), therefore I'm not familiar with technical details. Like Jenna Marie already said, it's best to contact their office directly, and ask for first hand information on any details. Most of this clinics have quite a lot work with current clients, so you will have to be little patient for replies.
At least to my knowledge, dr. Suporn is the only one of internationally known surgeons who keeps and incorporates all tissue (apart from testicles).
