The procedure you describe is not one that I am familiar with and therefore I cannot give you any advice. As you know, there are many procedures that are described in other countries. Some of them are no different than what we do and some of them have not been tested in a rigorous way (either by peer-reviewed studies or an organization like the FDA).
So, my only advice would be to fly back to Brazil and show the original surgeon exactly what you look like. Since it is a procedure we are not familiar with in this country, you will not likely find anyone who would be able to tell you what the final outcome may be.
One reason that medical tourism is a two-edged sword is precisely what you have experienced--you get a procedure that is only known in that country, and then you have few recourses when there are complications and you are now thousands of miles away.
You could also try e-mailing photos and asking your questions over the Internet, but I suspect that you need to be seen in person so they actually give you a better answer than "just wait".
