VANCOUVER, British Columbia — High frequency ultrasound is a helpful tool for precise evaluation for dermal fillers and scar localization, including their volume and borders with surrounding tissue, according to data presented at the 23rd Annual World Congress of Dermatology.
Researchers used high resolution 22 MHz and 75 MHz ultrasound for skin monitoring in 28 patients with dermal fillers side effects and 32 patients with scars.
The axial resolutions were 72 µ and 21 µ, respectively. Vertical ultrasound slicer images of 12.8 mm long, and depths of 10 mm at 22 MHz and 4 mm at 75 MHz were evaluated.
The researchers concluded that high frequency ultrasound can be used to measure objects in the depth of dermis and subcutaneous fat that can’t be evaluated with examination, palpation and optical methods of skin diagnosis.
The technique allows for an in-depth evaluation of dermal fillers and scar localization, the researchers said.
