Background and importance: High flow orbital apex or middle fossa cerebrospinal fluid (CSF) leaks can be life threatening and complex to repair. These leaks associated with large dural defects are most commonly repaired with an open temporalis muscle patch or free flaps, but these flaps do not always stop the leak. Clinical Presentation: A 65-year-old patient presented two years after orbital exenteration and radiation for squamous cell carcinoma. He developed multi-organism meningitis and pneumocephalus secondary to a large high-flow orbital apex/middle fossa CSF leak...

BACKGROUND: The tuberous breast syndrome is a condition that affects young women and can bring on serious disorders of self-esteem. There are numerous surgical techniques to correct this condition, but most of them include the use of breast implants to replace lack of volume. Nowadays, patients are increasingly becoming more demanding to get a definitive solution with minimal aesthetic sequelae. METHODS: We present a series of 11 patients with tuberous breast deformities treated with lipofilling technique...

BACKGROUND: Adipose-derived stem cells (ASCs), endothelial progenitor cells (EPCs) and soluble factors jointly contribute to the regenerative effect of fat grafts. The nanofat grafting technique is a simple method to mechanically emulsify the lipoaspirate and increase the ASC yield in the lipoaspirate. In the present study, we evaluated our extended nanofat grafting method that includes two additional centrifugation steps and results in a lipoaspirate of low volume that we termed "lipoconcentrate"...

Yong Woo Lee, Tae Hwan Park
BACKGROUND: Along with advances in thread lift techniques and materials, ancillary procedures such as fat grafting, liposuction, or filler injections have been performed simultaneously. Some surgeons think that these ancillary procedures might affect the aesthetic outcomes of thread lifting possibly due to inadvertent injury to threads or loosening of soft tissue via passing the cannula in the surgical plane of the thread lifts. The purpose of the current study is to determine the effect of such ancillary procedures on the outcome of thread lifts in the human and cadaveric setting...

The main objective of this study is to develop an efficient and environmentally gentle process for production of trans-free plastic fats. To acheive this, the core-shell structured magnetic composites were prepared, and then imidazole-based ionic liquids (ILs) were covalently grafted on the magnetic composites. Thereafter, Candida rugosa lipase was immobilized on the magnetic IL-functionalized composites. The immobilized lipase could be facilely separated using an external magnetic filed. With the magnetic biocatalyst, enzymatic interesterifications of solid palm stearin and liquid rice bran oil blends were performed at 45 °C...

In developed countries, over 100 million people per year form scars, of which 30% become hypertrophic. These scars are defined histologically by the presence of persistently contractile myofibroblasts. Recent in vitro research suggests that certain bone morphogenic proteins (BMP) can induce scar myofibroblast dedifferentiation and reprogramming into adipocytes. Since platelets contain BMPs within their granules, it is possible that platelet-rich plasma (PRP) can act as a vehicle to deliver BMP to sites of scarring or potential scarring...

Background: The fat grafting process includes the 4 phases of tissue harvesting, processing, recipient-site preparation, and reinjection. Among them, the preparation of the recipient site has never been exhaustively reviewed. We aim to provide a comprehensive overview of the methods to prepare the recipient site through external expansion with the resulting outcomes. Methods: PubMed/Medline database was searched for studies on fat grafting recipient site preparation by applying the following algorithm: ((fat grafting) OR (lipofilling) OR (lipograft) AND (recipient site))...

Tear trough deformity has been an area that has received much attention in terms of esthetic improvements. Fat transposition has been commonly used for the treatment of tear trough deformity. As some patients have had minimal improvement by that method, we propose the use of fat grafting combined with open blepharoplasty to complement the sunken area, including some of anterior maxilla region, and evaluate and precisely remove the excessive tissue.Lower blepharoplasty was performed by separating the skin and muscle flap...

Conservative breast surgery followed by irradiation, often referred to as Breast conserving therapy (BCT), has replaced modified radical mastectomy for the treatment of early stage invasive breast cancer and ductal carcinoma in situ (DCIS). About 10% to 40% of the patients treated with BCT have poor cosmetic outcome results. Small tumours in large breasts can be successfully treated by lumpectomy and radiotherapy, with good cosmetic outcome. However when the tumour breast ratio is higher, the cosmetic outcome can be very disappointing...

Background: Autologous fat grafting (AFG) to the breast is a frequent procedure in aesthetic and reconstructive surgery. Despite pure volume gain, questions remain regarding the engraftment rate, quality, and longevity. Little is known about the role of recipient tissue or innervation of the grafted area. Objectives: The goal of this study was to determine the optimal recipient layer and muscular the pretreatment of AFG. Methods: Fat was grafted to the breast, pectoralis muscle, or adjacent subcutaneous tissue of 42 rats...

Importance: The use of autologous fat transfer (AFT) or lipofilling for correcting contour deformities is seen as one of the major breakthroughs in reconstructive plastic surgery. Its applications in facial reconstructive surgery have been of particular interest owing to the prospect of achieving autologous reconstruction by a minimally invasive approach. However, its unpredictability and variable degree of resorption have limited its utility and much skepticism still exists regarding its efficacy...

BACKGROUND: Deficiency of the median tubercle is a common residual deformity after repair of cleft lip. The purpose of this study was to analyze the change in labial contour after insertion of a dermis-fat graft. METHODS: Patients with repaired cleft lip who underwent secondary dermis-fat grafting of the median tubercle between 2012 and 2015, along with preoperative and greater than or equal to 3-month postoperative three-dimensional photographs, were included. The photographs were registered to one another and measurements made before and after grafting using anthropometric landmarks...

Postmastectomy breast reconstruction (PMBR) has evolved dramatically since it was first described by Vincent Czerny in 1895. The increasing numbers of mastectomy procedures and improved patient survival have placed an increasing emphasis on the aesthetic and psychosocial outcomes, prompting surgeons to develop more sophisticated methods to reconstruct the breast mound. Significant improvements have been made to existing implant and autologous methods of PMBR in recent decades in an effort to reduce donor site morbidity and complication rates and improve cosmesis...

No current clinical treatments provide an ideal long-term solution for repair of long bone segment defects. Incomplete healing prevents patients from returning to preinjury activity and ultimately requires additional surgery to induce healing. Obtaining autologous graft material is costly, incurs morbidity, requires surgical time, and quality material is finite. In this pilot study, 3D printed biomimetic scaffolds were used to facilitate rapid bone bridging in critical sized defects in a sheep model. An inverse trabecular pattern based on micro-CT scans of sheep trabecular bone was printed in polybutylene terephthalate...

Introduction: Thin women have fewer autologous tissue breast reconstructive options than their higher body mass index counterparts-due to a lack of adequate donor sites. They are therefore usually offered expander/implant techniques. The total autologous latissimus dorsi flap is generally used in "well-padded" individuals, as they have enough fat on their back on which a completely autologous reconstruction could be based. When implant-based reconstruction is contraindicated (for instance due to planned adjuvant radiotherapy) or unacceptable to the patient, the total autologous latissimus dorsi flap can provide adequate tissue volume by utilizing the additional back fat deposits even in the thin, small-breasted patient...
