Results seem to vary. I don\'t think there is any particular consensus on a \"best\" doctor. Some have had good results with one doctor while others have had not so good results with the same doctor. This forum is certainly one of the best places to do your research but there are many factors that determine overall results many of which are determined by the recipient of the procedure, not just the doctor/physician and the product/procedure.
Doctor C in Tijuana and Dr. N in Prague are among the most popular for
PMMA, but again results are varied. You can try non-surgical methods such a stretching, pumping, etc, but in my experience these methods offer very little long-term gain and require a lot of work.
