I've seen a dozen of cases like this one. The fact is, plastic surgeons who are still using silicone in cosmetic facial augmentation are just lazy and don't want to give up their old techniques. I have seen some good chin implants but those are simple, and still get botched now and again. The only place silicone belongs is in boobs.
Medical science is moving faster now (since the advent of the internet) than ever before. A lot of surgeons are just sub par at keeping up with it. Medpor is superior to silicone. There are other materials superior to medpor, but they're too new and only a select few surgeons around the world are practicing with them.
I think cases like the one SJ showed are really alarming for a number of reasons. He seems like the ideal candidate for jaw angle implants. The surgeon was proud enough of this horrific result to publish it for advertising purposes. I've seen CT scans of patients skulls after silicone was removed, and there is a CLEAR bone erosion occurring under the implant, even to a civilian like me.
I would like to end with the fact I have seen good results from medpor. HA does not work in the jaw angles because of granule migration. Bio-OSS seems to only work in small quantities. Bone grafts get resorbed as onlays. PEEK is promising, and probably comparable in quality to medpor, if not slightly better. At the end of the day, implantology just isn't there yet. Osteotomies remain the gold standard of bone augmentation.
f**king lol at getting jaw angle implants when u already look like Jason Statham
