Hello, I did two rhinoplast back in 2007 ad 2008 and wanted to to a liquid corrective rhinoplasty to address the tip of my nose that is still a bit droopy but was concern with the scar tissues and the displacement of the veins and arteries that resulted from my first surgeries . While my injector will use a canula and all the time he needs to work on placing the product safely, I was wondering if there were any ways to see how my blood flow could be looking like in that area. Thank you.
