This increase in its popularity has led to the development of new technologies to increase its efficacy and safety, however, it has inherently implied the inadequate use of this procedure, mainly when performed by unqualified medical personnel. We present the case of a patient with complications following a breast AFT for aesthetic purposes, performed by a general practitioner without a specialty in plastic and reconstructive surgery.展开更多

Two facial asymmetry patients are presented with history of fat grafting to the mandibular angle areas. Collected fat from these formerly fat grafted zones and swollen on subsequent extra body weight gain has been re-grafted in the temporal regions for contour enhancement and has retained volume as photographically documented up to 30 months.展开更多

In the present study, we investigated the histological and morphometric changes after large volumes of fat were grafted within the subcutaneous cellular tissue. An experimental study was designed using four 3-month-old male pigs. One hundred cc of decanted fat tissue was transferred into the right leg. Volume augmentation achieved by auto lipo-injecting within the subcutaneous cellular tissue persisted up to two months. Although there is a reduction in cell number and size, an increased amount of extracellular matrix and the presence of oily cysts and microcalcifications were observed. <strong>Conclusion:</strong> The volume augmentation, which is achieved by autologous fat transfer in large quantities in subcutaneous cellular tissue, can remain for months.展开更多

Methods of dissection trended towards progressively aggressive surgery with deeper dissection for repositioning of ptotic facial tissues. In recent decades, the pendulum has swung towards more minimally invasive options. Likewise, there has been a shift in focus from repo-sitioning alone to the addition of volumization for facial rejuvenation. The techniques in this article are reviewed in a chronologic fashion with a focus on historical development as well as brief discussion on efficacy in relation to the other existing options. There is currently no gold standard technique with a plethora of options with comparable efficacy. There is controversy over which approach is optimal and future research is needed to better delineate optimal treatment options, which may vary based on the patient.
