BACKGROUND: Fat grafting to the aging face has become an integral component of esthetic surgery. However, the amount of fat to inject to each area of the face is not standardized and has been based mainly on the surgeon's experience. The purpose of this study was to perform a systematic review of injected fat volume to different facial zones. METHODS: A systematic review of the literature was performed through a MEDLINE search using keywords "facial," "fat grafting," "lipofilling," "Coleman technique," "autologous fat transfer," and "structural fat grafting...

Cosmetic and reconstructive surgeries always have a primary aim of the best outcome for the patient, with a big emphasis on the aesthetics. Lipomodelling is one such technique, originally described over a century ago but still used to this day, to provide a patient with the highest quality results. This is particularly true for lipomodelling of the breast, whether it be purely cosmetic, or for a post-mastectomy reconstruction for a breast cancer patient. Lipomodelling provides an effective way of restoring and even improving the look and aesthetics of the breast and of helping achieve the patient's expectations...

Fat embolism is an incidental finding in cases of long bone fractures or other trauma, but it is also associated with liposuction and autologous fat transfer, a procedure where fat from liposuction is injected back into the same patient's face, breast, buttocks or penis. We here present a case of sudden death by fat embolism in a healthy young male, caused by a simple penis enlargement procedure, in which fat was injected into the penis shaft. We suggest that the risk of fat embolization might be higher when pretraumatized tissue is subjected to fat injection, like in this case, where a penis elongation was performed before the fat injection...

More and more breast cancer patients prefer autologous fat tissue transfer following lumpectomy to maintain perfect female characteristics. However, the outcome was not satisfactory due to the transplanted fat absorption. In this study, we prepared two RADA16-I peptide scaffolds with and without tamoxifen. Both scaffolds were transparent, porous, and hemisphere-shaped. The hADSCs isolated from liposuction were attached to the scaffold. The growth inhibition of the hADSCs induced by TAM in 2-demensional (2D) culture was higher than that in TAM-loaded hydrogel scaffold 3D culture (P < 0...

OBJECTIVE: The aim of this study was to describe a technique for midface rejuvenation combining lower blepharoplasty, midcheek lift and autologous fat transfer. METHODS: All patients who underwent a midface rejuvenation procedure performed by the same surgeon and using a classic subciliary blepharoplasty surgical approach were identified. The technique combined three distinct procedures: lower blepharoplasty with use of a transposition flap of orbital adipose tissue in the medial and central compartment to reduce the subpalpebral bags and attenuate the palpebrojugual sulcus; midcheek lift in the preperiosteal plane with trans-osseous fixation exerting traction on the soft tissues of the cheek along several vectors; autologous fat transfer to offset the loss of volume in the target area...

Autologous fat grafting is quite common for breast augmentations as well as for reconstructive breast surgery. Coleman has described the surgical technique of fat grafting. Fat is harvested, and after centrifugation and refinement, blunt infiltration cannulas are used to place the fat through small incisions. The grafted tissue is placed in small aliquots with each withdrawal of the cannula. In order to achieve an aesthetically pleasing contour of the breast, the fat should be layered into different levels from the chest wall to the skin...

INTRODUCTION: Autologous fat grafting (AFG) can be used as an adjunct in breast cancer surgery to improve contour defects. Few previous studies have assessed patient reported outcomes (PROs) for AFG. This study analysed AFG use and assessed PROs in terms of physical and psychosocial well-being. MATERIALS AND METHODS: All patients undergoing AFG were identified from a prospective database and asked to complete the validated BREAST-Q questionnaire and a tool to assess patient-perceived change after AFG (5-point Likert-type scale)...

Cumulative long-term exposure to solar ultraviolet radiation promotes premature skin aging characterized by wrinkle formation and reduced skin elasticity. In this study, we assessed whether microfat transfer could improve dermal and subcutaneous tissue thickness loss associated with photoaging. Twenty-one patients affected by facial photoaging (photodamage grade II-IV; age range 35-62 years; 19 females, 2 males; all of Caucasian origin) were treated using minimally invasive autologous dermal white fat transfer harvested with a recently designed microcannula...

Vaginal atrophy is a common condition among peri- and post-menopausal women. Symptoms of vaginal dryness, pruritus, irritation, loss of subcutaneous fat, sparse pubic hair and dyspareunia occur due to decreased estrogen level. Estrogen-based treatments are effective. But many patients are reluctant to be treated due to health concerns. As alternatives, we explored the efficacy of platelet-rich plasma (PRP) and lipofilling. A 67-year-old female patient with vaginal atrophy was referred to our department. Treatment using estrogen cream had failed to improve patient's symptoms...

REVIEW
James Frame
The 'waterfall effect' is a descriptive term to indicate a sliding ptosis of parenchymal breast tissue over a fixed or encapsulated implant. It occurs more frequently than surgeons anticipate and especially over the longer term after augmentation. Certain breast implants are more prone to contribute to this problem as are implants placed in submuscular pockets that ride high, especially in women with anatomical musculoskeletal variance or asymmetry. This article describes the aetiology of sliding ptosis in more detail, the relevant anatomy and the surgical correction...

Autologous fat transfer, or lipofilling, is a common technique used for soft tissue reconstruction. It has been used for many years, but the technique is associated with a significant graft resorption rate (20% to 80%). To improve the fat graft survival rate, several methods have been tested, and one has appeared more promising: cell-assisted lipotransfer (CAL). In the CAL method, fat is enriched with adipose-derived stromal cells (ASC), contained in the stromal vascular fraction (SVF) obtained after enzymatic digestion of fat or after cell culture to improve the fat survival rate...

BACKGROUND: The aim of breast conserving surgery (BCS) is to excise the cancer with clear margins whilst at the same time leaving a good or excellent cosmetic result. A significant percentage of women, who have large cancers or have limited breast volumes, achieve poor cosmetic outcomes. BCS with immediate volume replacement using lipofilling or autologous fat transfer is a new technique. The aim of this study was to evaluate the cosmetic outcomes of a pilot study of patients having BCS and immediate lipofilling performed in The Edinburgh Breast Unit...

Soft tissue reconstruction to restore volume to damaged or deficient tissue beneath the skin remains a challenging endeavor. Current techniques are centered around autologous fat transfer, or the use of synthetic substitutes, however, a great deal of scientific inquiry has been made into both the molecular mechanisms involved in, and limitations of, de novo adipogenesis, that is, the formation of new adipose tissue from precursor cells. To best comprehend these mechanisms, an understanding of defined markers for adipogenic differentiation, and knowledge of both commercially available and primary cell lines that enable in vitro and in vivo studies is necessary...

Adipocyte-derived vascular endothelial growth factor-A (VEGF-A) plays a crucial role in angiogenesis and contributes to adipocyte function and systemic metabolism, such as insulin resistance, chronic inflammation, and beiging of subcutaneous adipose tissue. Using a doxycycline-inducible adipocyte-specific VEGF-A-overexpressing mouse model, we investigated the dynamics of local VEGF-A effects on tissue beiging of adipose tissue transplants. VEGF-A overexpression in adipocytes triggers angiogenesis. We also observed a rapid appearance of beige fat cells in subcutaneous white adipose tissue as early as 2 days postinduction of VEGF-A...

OBJECTIVES: Ablative procedures of the head and neck often result in significant facial and cervical irregularities and cosmetic asymmetry. The deformity resulting from ablative procedures of the head and neck is a significant source of cosmetic morbidity and postoperative dissatisfaction. Reconstruction of post-ablative defects in the head and neck can employ a broad range of techniques, ranging from primary closure to free tissue transfer. The free dermal fat graft (FDFG) is one such option and has been used to repair volume defects of varying sizes after common head and neck procedures such as parotidectomy...

INTRODUCTION: Autologous fat grafting is a valuable tool in the correction of facial soft tissue asymmetry and volume deficits. Pubertal growth and fluctuations in body mass present unique challenges to achieving satisfactory results after autologous fat transfer in the pediatric population. Few studies exist describing the outcomes and complications of pediatric facial fat grafting. The objective of this study is to identify the complication profile and outcomes after autologous fat grafting for the correction of facial asymmetry and volume deficits in the pediatric population...

INTRODUCTION: Nowadays, there is an increasing demand for contouring of the entire lower leg, in addition to corrections at the level of the muscle only. Accordingly, it becomes advantageous to use fat tissue for this purpose, for its availability in high quantities, potential for its easy implantation in all leg parts, biological compatibility, low antigen potential, and minimal donor morbidity. METHODS: Forty-eight female patients, aged 20-54 (47.1 % younger than 35 and 52...
