I would agree with Bighat. As a physician who does cosmetic surgery in the US, I can tell you that the general consensus is \"permanent filler= bad, temporary filler = great!\" Part of this is because as you age, at least in the face, there are changes that occur around the filler such that you may not want something permanent lodged against something that is changing. It may not look as good in 15-20 years as it does when the face is much fuller and more elastic. Also, if the patient doesn\'t like the filler, it\'ll go away in 6-18 months depending on the filler used.
For some general plastic surgeons, temporary fillers and botox have become the bread and butter of the practice. I\'m not a general plastic surgeon but I\'ve had ladies come in a spend $3-4000 every 6 months on their botox and filler indefinitely. And that takes 20-30 minutes. They leave happy and can be playing tennis in a few days feeling great.
My point in telling you this is, in medicine whatever way a certain physician does something is always the best way and he/she will have a million reasons to sway you against something he doesn\'t do or doesn\'t agree with. Do you own research, ask questions and don\'t just trust that one way is necessarily the only way. If the people you\'re talking to don\'t use PMMA for FDA approval or preference reasons, they\'re going to tell you not to do PMMA.
In the US, we don\'t really use PMMA much. If you ask the average doc in the US, he\'s going to want you to do juviderm,
Restylane,
Radiesse, etc and come back in 6 months and do it again.
PMMA is mentioned as permanent in some articles and semi-perm in other articles. Given the fact that its basically an acrylic and its also used in orthopedics to cement bone, I would venture to say its at the very least semi-permanent but on the order of decades vs a few years or permanent. Again, I don\'t use it at all so this is just my opinion based on knowledge of the physiology and characteristics/chemical makeup of the PMMA.
But its good that you\'re going into any procedure with reserve and questions. The procedure will be available whether you do it now or 2 years from now.
