Guys Lemperle still didn\'t reply, but I have found in my e-mail\'s inbox his answer it was in 2009 -
1- (my Q. was to him about long term complications after
PMMA injection ) :
It is true for Brazilian
PMMA (because it still contains small microspheres which stimulate macrophages and can cause a foreign body granuloma years after implantation (mainly after a systemic infection) . This is the risk - which can be treated effectively with local cortisone (triamcinolone) injections ! - I just treated the moon face of a lady in China , who got 110 cc of Artecoll in 2005 (when it was still impure) with 8 x 40 mg
Kenalog.
I have tested NewPlastic - and it is almost pure , e.g.free of small
PMMA microspheres, which might cause inflammation. The FDA approved ArteFill is absolutely pure and causes no granulomas anymore, however , it will be 10 or 20 times more expensive : 0.8 ml cost $ 450 to the doctor ! And you will need 10 -20 ml! Thank God, granulomas are rare (maybe 1 : 1000) Best wishes and regards,Gottfried
So it is true the Brazilian
PMMA still contain some small beads ---> macrophages stimulation ---> foreign body granuloma (1 : 1000) --->
Kenalog injection .
2- In another e-mail I have asked him about the possibilities of
PMMA beads migration in long-term :
of course I am biased since I developed this tissue process - but I was always honest enough to hear all critics and engulf them:
PMMA beads can be transported through open veins only during injection : that\'s why we have to increase its diameter in esophagus and urethra injections from 40 microns (venules are 20-30 microns in the skin) to 125 microns (submucous plexus has up to 80 microns in diameter). After the injection, however, no \"migration \" is possible anymore because the collagen keeps the beads in place until the collagen (( I think Lemperle ment here bovine collagen which takes a longer time to be completely resorbed than the cellulose )) is resorbed (within 3 weeks) and replaced by the body\'s own collagen (=granulation tissue) . This gr. tissue keeps the beads at the location where they had been injected. After injecting
PMMA into a penis, however, the whole implant can be moved as a total for 1 - 2 weeks - until tissue ingrowth has occurred . This is a crucial time to keep the penis as quiet as possible , because movement of skin may move the whole
PMMA forwards or backwards. After 3 weeks, however, no movement neither of the whole implant nor of a single bead is possible ! This can only occur with silicone or PAAG oil, which is not encapsulated and can slowly move according to gravity ! So what I understood from his e-mail (in 2009) that the bovine collagen (in e.g. Artefill or Artecoll) will prevent the beads from migration during the1st 3 weeks till it is completely replaced by your owen collagen, after 3 weeks no movement of the beads whats so ever.
In conclusion I think that was the reason why Lemperle has used bovine collagen (Artecoll and Artefill) in his invention and not cellulose (Newplastic and Mteacrill) .
So Artefill is more superior than Metacrill and Newplastic ( in regards the purity of the beads and the carrier)
