Long-term MRI Follow-up of Hyaluronic Acid Dermal Filler
Mobin Master, Stefania Roberts
Abstract
We present a case report of hyaluronic acid (HA) injected in the subcutaneous fat of the lateral face, deep fat compartments of the mid-face, and a combination of deep and superficial injection of HA in the chin. MRI demonstrates longevity of HA in the lateral face and deep fat compartments of the mid-face versus almost complete degradation of HA in the chin 19 months from injection. The MRI signal demonstrated no migration of HA and persistence of HA at 27 months in the lateral face and mid-face.
