Filler migration is a rare complication of dermal filler treatment. Although most research has found that more permanent fillers, such as silicone, are more likely to migrate due to their long-term presence in the body, there have also been reported cases of filler migration from short-term hyaluronic acid-based dermal fillers. As lip augmentation procedures are fast becoming one of the most frequently requested treatments in medical aesthetics, this article looks at the longevity of hyaluronic acid lip dermal fillers, while also aiming to assess the cause of dermal filler post-treatment migration and evaluating how to minimise its risk.
Abstract
Background
Autologous fat is known for a reliable and natural safety profile, but complications do occur—even serious vascular adverse events.
Objectives
The authors sought to examine doppler-ultrasound (DUS) imaging for the harvesting and subsequent facial implantation of autologous fat tissue.
Methods
All patients underwent lipofilling treatment of the temporal fosse of the face. DUS examination was performed for preprocedural vascular mapping and imaging of previously injected (permanent) fillers. In addition, the injection of autologous fat was performed DUS-guided.
Results
Twenty patients (all female; mean age, 57.9 years; range, 35-64 years). DUS examination showed that 16 of the 20 patients (80%) had been injected with resorbable or nonresorbable fillers elsewhere in the past. The temporal artery could be visualized and avoided in all cases. An average of 1.1 cc of autologous fat was injected in the temporal fossa per side. One case of edema and nodules was described, but no other adverse events were reported.
Conclusions
The utilization of DUS can add valuable information to a lipofilling procedure and should be considered an integral part of a safe lipofilling treatment.
