Cosmetic fillers are meant to enhance a person's beauty, but can cause damage and deformity if applied incorrectly.
However, ultrasound scans can help doctors prevent these ugly side effects by precisely guiding treatment to dissolve poorly placed fillers that are blocking blood vessels, researchers said Wednesday at the Radiological Society of North America's annual meeting.
Such use of ultrasound can improve treatment of vascular occlusion -- disruption of blood flow -- caused by misplaced fillers, researchers said.
"Vascular occlusion events in the face can be devastating, because, if they're not properly treated, they can cause necrosis and even facial deformation," researcher Dr. Rosa Maria Silveira Sigrist, an attending radiologist at the University of São Paulo in Brazil, said in a news release.
