POSSIBILITIES OF MAGNETIC RESONANCE IMAGING IN DIAGNOSING FILLERS IN PATIENTS WITH FACIAL SOFT-TISSUE SWELLING
The study aims to improve efficiency of magnetic resonance imaging diagnosis of facial soft-tissue swelling in patients after facial contouring surgery. Materials and methods. The article describes clinical cases of magnetic resonance imaging diagnosis of facial contouring complications developed after injections of hyaluronic acid fillers in 5 and 10 years’ time. Results. Areas of hyperintensive MR signal with distinct and smooth contours were determined in soft tissues of the maxillofacial region using T2-WI. The morphological substrate of such areas was represented by hyaluronic acid-based gel. In T2STIR mode and with fat tissue suppression of the MR signal, filler boluses were visualized more distinctly as compared to T2-weighed image without fat tissue suppression but with a hyperintensive MR signal maintained. According to clinical cases, magnetic resonance imaging has proven to be an informative method for diagnostics, which should be prescribed to patients with infiltrative changes after facial contouring surgery.
