Background: One of the challenges in breast reduction is to maintain breast projection with 45% of its volume in the upper pole and 55% in the lower pole. Although widely used in breast surgeries, the behavior of fat grafts is still not completely understood. Objectives: To evaluate by magnetic resonance imaging (MRI) the survival of fat transferred to the retropectoral plane in patients undergoing breast reduction, in the search for an oncologically safe procedure with high predictability and reproducibility...

While the lateral arm free flap has been well described, there is a relative paucity in its use compared to other free flaps and regional flaps. The lateral arm free flap is a unique soft tissue free flap that provides several reconstructive advantages in head and neck reconstruction: excellent contour and color match to facial skin, well compartmentalized fat, donor nerves for nerve grafting, and the ability to two-team harvest and close the donor site without a skin graft. A detailed anatomic and harvest technique is described, along with indications and advantages of using lateral free flap for head and neck reconstruction...

Even after long-term hormone therapy, many transwomen still have challenges in the size and shape of their breasts and also of the contour of their trunk areas. Though distinct anthropomorphic differences in skeletal structure exist and pose limitations to an ideal result, considerable improvements can be obtained through breast augmentation and trunk feminization. There are challenges that are unique to the transfeminine chest and trunk, and important considerations for the priority of fat grafting to the buttocks and hips when grafted fat is in short supply...

BACKGROUND: The relapse of hemifacial microsomia was thought to be highly related to the soft tissue envelope around the mandible angle mainly composed by masseter and medial pterygoid. According to the reason, we tried to apply masseter injection of type A botulinum toxin to weaken the soft envelope tension on the early stage post mandible distraction in adult HFM patients. METHODS: Eight patients diagnosed with HFM were studied and randomly assigned to an experimental or control group...

Autologous fat grafting is a surgical procedure used to correct volumetric defects, atrophies, and sclerosis. Three-dimensional (3D) facial photography may enable researchers to quantify the success of surgical procedures through volumetric and surface assessments. Using 3D photography, the authors assessed the results of autologous fat grafting performed in a 15-year-old patient affected by Parry-Romberg syndrome, a rare condition resulting in progressive hemifacial atrophy of skin, subcutaneous tissues and, ultimately, bone...

Cosmetic tourism is defined as patient mobility across borders, typically constituted by patients seeking cosmetic surgery at lower costs abroad. The most common procedures are abdominoplasty, fat grafting and breast augmentation. Very little is known about the complication rates after cosmetic tourism, and there is a paucity of evidence in all aspects of cosmetic tourism. In this review, we focus on post-operative complications i.e. post-operative infections, in particular with rare microorganisms such as mycobacteria...

Non-alcoholic steatohepatitis (NASH), with or without hepatocellular carcinoma (HCC) is a growing indication for liver transplantation (LT) worldwide, particularly in the western world. Patients with NASH typically combine features of metabolic syndrome with cardiovascular comorbidities, which challenge pre-LT evaluation, surgical approaches, post-LT management and outcomes. Post-LT survival in NASH patients is excellent, similar to that achieved with other indications, particularly in the absence of cardiovascular comorbidities...

INTRODUCTION: Fat grafting is extensively used in plastic surgery in last 2 decades. Here, we report the retrospective comparison of patients who underwent fractionated fat injection to blend the lid-cheek junction with those who had regular fat injection. METHOD: After obtaining institutional review board approval, a retrospective review of patients who underwent lower blepharoplasty with fractionated fat injection for blending lid-cheek junction from January 2014 through October 2015 was performed...

Background: Cell-enriched fat grafting has shown promising results for improving graft survival, although many questions remain unanswered. A large animal model is crucial for bridging the gap between rodent studies and human trials. We present a step-by-step approach in using the Göttingen minipig as a model for future studies of cell-enriched large volume fat grafting. Methods: Fat grafting was performed as bolus injections and structural fat grafting. Graft retention was assessed by magnetic resonance imaging after 120 days...

Introduction: The development of novel immunomodulatory strategies that might decrease the need for systemic immune suppression would greatly enable the utility of cell-based therapies. Cell transplantation on biomaterial scaffolds offers a unique opportunity to engineer a site to locally polarize immunogenic antigen generation. Herein, we investigated the localized delivery of IL-33, which is a novel cytokine that has been shown to have beneficial immunomodulatory effects in certain transplant models as mediating anti-inflammatory properties in the adipose tissue, to determine its feasibility for use as an immunomodulatory agent...

Tissue engineered scaffolds for adipose restoration/repair has significantly evolved in recent years. Patients requiring soft tissue reconstruction, caused by defects or pathology, require biomaterials that will restore void volume with new functional tissue. The gold standard of autologous fat grafting (AFG) is not a reliable option. This review focuses on the latest therapeutic strategies for the treatment of adipose tissue defects using biomolecule formulations and delivery, and specifically engineered biomaterials...

Adipose-derived therapies have increased in popularity for treatment of painful orthopaedic conditions, such as osteoarthritis. We report the passage of fat into a Baker's cyst after injection of micro-fragmented adipose tissue in a patient with bilateral knee arthritis. Following fat grafting, the patient required drainage of fatty fluid from within the Baker's cyst on multiple occasions. Approximately 3 months postprocedure, she began to notice an improvement in her knee pain with no further recurrence of pain or swelling from her Baker's cyst...

BACKGROUND: Autologous fat injection is a procedure aimed at eliminating grave defects in the skin surface by subcutaneous injection of the patient's fatty tissue. Fat embolism is a rare but severe complication of this procedure, especially cerebral infarction. It is first reported by Thaunat in 2004. METHODS: were presented to the hospital with sudden unconsciousness and left limb weakness in 24 hours after facial fat injection. Brain computed tomography and magnetic resonance imaging were performed immediately after admission...

Forehead aging is characterized by wrinkles, loss of skin elasticity, brow ptosis, and soft-tissue atrophy. For patients with prominent rhytids and marked brow ptosis, forehead lift is still the most effective treatment with a persisting result. In order to eliminate the glabellar wrinkles, forehead lift usually requires the removal of the corrugator supercilii muscle and procerus, which can lead to glabellar flattening or depression. Instead of muscle removal, the corrugator supercilii muscle, procerus, and the underlying galea were dissected as a pedicled glabellar flap...
