Why did Radiesse dissolve? What are my options given that I have risked blindness twice? (Photos)

In some countries Hylase contains hyaluronidase, which is what was used to dissolve the filler you had injected which I assume was an HA filler. Hylase will not dissolve Radiesse. 

Thanks for your questions and photos.  Hyaluronidase can't dissolve Radiesse because Radiesse is not made of hyaluronic acid.  Perhaps the hyaluronidase dissolved some of your native collagen, but it is hard to say.  I would say you are putting yourself at risk with Radiesse in the forehead with those large arteries, but the biggest risk would be skin and soft tissue necrosis when one of those arteries above the brows is occluded.  You could end up with a very large and unsightly scar if the skin is deprived of oxygen and nutrients from those arteries and I have seen it happen when an inexperienced injector made a choice that cost the patient half her forehead skin.  Hopefully you are seeing a board certified plastic surgeon, who might propose something along a more surgical route if the forehead indentation is your biggest concern.  Best of luck and be careful out there!

Hyaluronidase is an enzyme that breaks down Hyaluronic acids (Juvederm, Restylane, Belotero, Voluma, etc.) and has no effect on Radiesse.  There IS something which can break down Radiesse: Sodium Thiosulfate!  This was found and tested by Yale Dermatologist, Deanne Mraz Robinson, MD, and published in a peer-reviewed journal of cosmetic dermatology in November 2018.
Apparently, you had some hyaluronic acid in an area that you thought was occupied by Radiesse.
