Kliniec K, Domagała Z, Kempisty B, Szepietowski JC. Arterial Vascularization of the Forehead in Aesthetic Dermatology Procedures: A Review. J Clin Med 2024; 13:4238. [PMID: 39064278 PMCID: PMC11278280 DOI: 10.3390/jcm13144238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2024] [Revised: 07/11/2024] [Accepted: 07/17/2024] [Indexed: 07/28/2024] Open
Abstract
Background: The growing popularity of aesthetic procedures on the face raises the question of their safety. The forehead region is crucial aesthetically, but due to its abundant vascularization, it is also one of the most dangerous areas for dermatologic procedures, especially in the glabella area. The purpose of this article is to review the literature on the arterial vascularization of the forehead to identify potential high-risk zones for aesthetic dermatology procedures. Methods: A database search (PubMed, Web of Science, Scopus, and Embase) was conducted, and the titles and abstracts of all identified studies were screened, followed by full-text evaluation. Results: We identified 714 articles during the database search, and 25 articles were included in the review. The included studies used cadaveric dissection and computed tomography applied to cadavers as well as Doppler ultrasonography on volunteers to evaluate the forehead arteries (supratrochlear (STrA), supraorbital (SOA), central (CA), paracentral artery (PCA), and frontal branch of superficial temporal artery(FBSTA)). A total of 1714 cases involving the forehead arteries were analyzed. The included arteries were observed over a relatively large area, and their locations varied. The CA and PCA in cadaver studies were observed in an area of 0.2 to 10.8 mm and 0.8 to 16.2 mm, respectively, on the entire path from the glabellar point to the frontal prominence point. The distances from the midline in cadaveric studies at various measurement points ranged from 0.6 to 28.0 mm for the superficial branch of the STrA and 13.6 to 40.7 mm for the deep branch of STrA. In case of SOA, the distance from the midline ranged from 23 to 32 mm. Measurements from the midline in Doppler studies ranged from 0 to 23 mm for STrA and from 10 to 50 mm for the SOA. In studies using computed tomography, STrA was observed at a distance of 11 to 21 mm and the SOA at a distance of 21 to 32 mm, both lateral to the midline. Conclusions: Medical professionals should be aware of zones where frontal arteries are more likely to be encountered. The glabella region appears to be one of the most dangerous areas for dermatologic procedures. It is believed that the supratrochlear, supraorbital, and the paracentral arteries may cause ophthalmic complications due to occlusion of the ophthalmic artery, while this risk for the frontal branch of the superficial temporal artery seems to be low but cannot be completely excluded.

Abstract
Parry-Romberg syndrome is a rare acquired disorder characterized by unilateral idiopathic progressive atrophy of the skin and soft tissues of the face, resulting in a sunken appearance. The muscles, cartilage, and underlying bony structures may also be affected. The etiology remains unclear and is based on several hypotheses. The incoherence of atrophy and the development of associated symptoms make the diagnosis, prognosis, and management of patients difficult. Here, we report the case of a 10-year-old boy who presented to the Department of Pediatric Dentistry at the Mohamed V Military Training Hospital in Rabat with progressive left hemifacial atrophy and was diagnosed by a pediatric rheumatologist as having Parry-Romberg syndrome. On extraoral examination, the patient presented a slight facial asymmetry and a small, dark, linear scar in the left zygomatic region. Intraoral examination revealed a left lateral open bite and atrophy of the left side of the tongue. Panoramic radiography showed incomplete eruption of the left mandibular first and second premolars (34/35), with significant root atrophy giving a narrowed appearance to the corresponding pulp chambers confirmed on retro alveolar radiographs. The mandible had a slightly reduced ramus height on the affected side confirming the patient's facial asymmetry. A better understanding of this syndrome will help to improve oral care in young patients.

Aesthet Surg J 2023; 43:NP704-NP712. [PMID: 37289983 DOI: 10.1093/asj/sjad184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 05/25/2023] [Accepted: 05/30/2023] [Indexed: 06/10/2023] Open
Abstract
BACKGROUND The efficacy of stromal vascular fraction (SVF) treatment, or stem cell treatment, directly depends on the SVF cell count and the cells' viability. The SVF cell count and viability are in direct correlation with the adipose tissue harvesting site that yields SVF cells, making this research a contribution to developing tissue guidance. OBJECTIVES The aim of this study was to investigate the importance of harvesting subcutaneous adipose tissue-derived SVF cells on the concentration and viability of SVF. METHODS Adipose tissue was collected by vibration-assisted liposuction from the regions of the upper and lower abdomen, lumbar region, and inner thigh region. With the semiautomatic UNISTATION 2nd Version system, the obtained fat was chemically processed (with collagenase enzyme) and a concentrate of SVF cells was obtained by centrifugation. These samples were then analyzed with the Luna-Stem Counter device to measure the number and viability of SVF cells. RESULTS When comparing the regions of the upper abdomen, lower abdomen, lumbar region, and inner thigh, the highest concentration of SVF was found in the lumbar region, specifically at an average of 97,498.00 per 1.0 mL of concentrate. The lowest concentration was found in the upper abdominal region. When ranking the viability values, the highest cell viability of SVF was observed in the lumbar region, measuring 36.6200%. The lowest viability was found in the upper abdominal region, measuring 24.4967%. CONCLUSIONS By comparing the upper and lower abdominal, lumbar, and inner thigh regions, the authors have come to the conclusion that, on average, the largest number of cells with the highest viability was obtained from the lumbar region.

Lipoinjection with Adipose Stem Cells for Nasal Modeling: Rhino Cell, a Highly Versatile Alternative. Arch Plast Surg 2023; 50:335-339. [PMID: 37564724 PMCID: PMC10411243 DOI: 10.1055/a-2067-5481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 02/15/2023] [Indexed: 04/03/2023] Open
Abstract
It is undeniable that a significant number of patients who want to improve their facial appearance is increasingly interested in nonsurgical procedures. Without a doubt, the use of autologous fat could not be left out as a magnificent alternative for nasal modeling simply because of four influential factors: ease of collection, compatibility, the temporality of the results, and safety. This work describes an innovative alternative technique for nasal modeling using micrografts enriched with adipose-derived mesenchymal stem cells (ASCs). With this technique, fat was collected and divided into two samples, nanofat and microfat. Nanofat was used to isolate the ASCs; microfat was enriched with ASCs and used for nasal modeling. Lipoinjection was performed in a supraperiosteal plane on the nasal dorsum. Through a retrolabial access, the nasal tip and base of the columella were lipoinjected. We consider that nonsurgical nasal modeling using micrografts enriched with ASCs can be an attractive and innovative alternative. This technique will never be a substitute for surgical rhinoplasty. It can be performed in a minor procedure area with rapid recovery and return to the patient's daily activities the next day. If necessary, the procedure can be repeated.

Abstract
BACKGROUND For decades, facial fat grafting has been used in clinical practice for volume restoration. The main challenge of this technique is variable volume retention. The addition of supplements to augment fat grafts and increase volume retention has been reported in recent years. OBJECTIVES The aim of this systematic review was to investigate which supplements increase volume retention in facial fat grafting as assessed by volumetric outcomes and patient satisfaction. METHODS Embase, Medline, Ovid, Web of Science Core Collection, Cochrane Central Register of Controlled Trials, and Google Scholar were searched up to November 30, 2020. Only studies assessing volume after facial fat grafting with supplementation in human subjects were included. Outcomes of interest were volume or patient satisfaction. The quality of the studies was assessed with the Effective Public Health Practice Project tool. RESULTS After duplicates were removed 3724 studies were screened by title and abstract. After reading 95 full-text articles, 27 studies were eligible and included for comparison. Supplementation comprised of platelet-rich plasma, platelet-rich fibrin, adipose tissue-derived stromal cells or bone marrow-derived stromal cells, cellular or tissue stromal vascular fraction, or nanofat. In 13 out of 22 studies the supplemented group showed improved volumetric retention and 5 out of 16 studies showed greater satisfaction. The scientific quality of the studies was rated as weak for 20 of 27 studies, moderate for 6 of 27 studies, and strong for 1 study. CONCLUSIONS It remains unclear if additives contribute to facial fat graft retention and there is a need to standardize methodology. LEVEL OF EVIDENCE: 4

Abstract
Parry Romberg syndrome (PRS), also known as progressive hemifacial atrophy, is a very rare self-limiting disease, which affects the skin and subcutaneous tissues, underlying musculature, cartilage, and bony structures of one half of the face with a resultant hemiatrophy and alopecia areata. It presents in children and young adults, with a slow progression of the atrophy for several years, and then becomes stable. Magnetic resonance imaging (MRI) or computed tomography (CT) scan of the cranium demonstrates the radiological feature of hemiatrophy very clearly. We report a case of PRS in a nine-year-old girl with characteristic features which was diagnosed based on medical history, clinical signs, and radiological findings on cranial CT scan and MRI.

Abstract
OBJECTIVE In this study, we investigate the biological characteristics of ADSCs from the liposuction area in patients with hemifacial atrophy in vitro. METHODS ADSCs were respectively extracted from the donor site of patients with hemifacial atrophy and healthy ones. ADSCs of two groups were respectively tested for proliferation ability, phenotype, multipotency, migration ability, self-repair ability, apoptosis, and autophagy. Exosomes extracted from the supernatant of two groups were detected by NTA particle size, electron microscopy (TEM), and WB for CD63 and TSG10, respectively. RESULTS CCK-8 showed a statistically less increase in cell proliferation in PHA-ADSCs after the sixth day. ADSCs in both groups had typical phenotypes and multidirectional abilities. PHA-ADSCs exhibited weaker droplet formation. The cell migration ability in PHA-ADSCs was weaker tested by Transwell assay. The live/dead proportion calculated by ImageJ following calcein-AM/PI double staining revealed live cells in PHA-ADSCs was 46.11% compared with 54.21% in NORM-ADSCs after OGD treatment. A significant down-regulation of ATG7 and ATG12 and a higher percentage of apoptosis were found in PHA-ADSCs. A significant up-regulation of BAX occurred in PHA-ADSCs.ARPC5 expression in the PHA group was extremely distinct down-regulated.CDKN1A and CDKN2A expression in the PHA group was significantly up-regulated.WB analyses confirmed that both groups' ADSCs-Exosomes surface markers CD63 and TSG101 were positively expressed but varied significantly. CONCLUSIONS PHA-ADSCs exhibited a poorer proliferation ability, higher apoptosis percentage, weaker lipid droplets formation, weaker cell migration, poorer intolerance to OGD, aging earlier, and weaker self-renewal and repairability.PHA-ADSCs-Exosomes showed low expressions of CD63 and TSG101.This study provides strong evidence that the addition of exosomes with specific cytokines can improve the fat survival rate after fat filling in patients with hemifacial atrophy.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Understand age-related changes to the face and neck and pertinent anatomy and discuss important aspects of fat graft harvesting, processing, and infiltration. 2. Recognize key differences between common techniques for fat processing and infiltration and develop a plan for patients based on site-specific facial anatomical zones. 3. Appreciate the utility of fat grafting as an adjunct to other facial rejuvenating procedures such as face lift and blepharoplasty procedures and list the potential complications from fat grafting to the face and neck. SUMMARY Fat grafting to the face and neck aids in volume restoration, thereby addressing soft-tissue atrophy associated with the aging face, acquired conditions, or congenital malformations. Often, fat grafting may sufficiently restore facial volume alone or in conjunction with other facial rejuvenation procedures. Facial/neck fat grafting requires a systematic and thoughtful approach, with special care to atraumatic technique. This CME article covers the principles and techniques for modern facial fat grafting to the face and neck. Increasing data support the ability of autologous fat to produce significant and sustainable appearance-related changes. The authors follow the general principles of the Coleman technique for facial fat grafting and have observed tremendous success over the years. Other techniques for facial fat grafting are also discussed including microfat and nanofat processing. As the understanding of facial fat compartments continues to evolve, the authors may better predict fat grafting outcomes following augmentation. Finally, the technique described as "lipotumescence" has been successfully used in the breast and other regions of the body that have radiation damage and is discussed in this article specifically for the face and neck.

Abstract
Progressive haemifacial atrophy, also known as Parry-Romberg syndrome. Lipofilling provides an option for voluminous flaps, improving skin quality and preserving the natural contours of the face. Fat reinjection is a simple, efficient and reproducible procedure. Physical appearance and psychological well-being should be considered as a part of the general management.
Introduction The aim of this paper is to present our experience using autologous fat transplantation for facial augmentation and to evaluate the effectiveness of lipofilling in different regions of the face for the reconstruction and aesthetic improvement of the facial contouring. Case presentation Data in term to the age, gender distribution, harvest and injection sites, degree of satisfaction with post-surgical facial, and complications were recorded. Discussion Progressive haemifacial atrophy, also Known as Parry Romberg's disease, is a common craniofacial disease that conventionally affects the subcutaneous tissue on one side of the face. We report here a series of 27cases of hemifacial atrophy (Parry-Romberg syndrome), admitted to our department, and treated with lipofilling in conformity with Coleman's guidelines. The volume of fat grafting was assessed by an attempt to reach symmetry with the controlateral side within a single procedure. Conclusion All patients claimed that they were satisfied or very satisfied with the aesthetic results and affirmed that it had a positive psychological impact on their daily life.

Abstract
Malformations of the maxillofacial region has disturbing psychosocial effects and causes enormous socioeconomic concerns. The management of maxillofacial defects caused by congenital anomalies, trauma, osteoporotic fractures, periodontitis, or cancer treatment is challenging for oral and maxillofacial surgeons. Numerous approaches have been recommended for the managing of these deficiencies. The traditional treatment for maxillofacial defects or their repair is an intricate process by autologous bone grafts from the scapula, ribs, fibula, or iliac crest origins. Regenerative medicine is well thought-out as a perfect substitute approach for autologous bone grafts to renovate bone deficiencies. The use of stem cells has improved results and offered a technique to reconstruct craniofacial bone defects. The field of tissue engineering for the regeneration of maxillofacial needs integration of biochemical and biomaterial engineering aspects with cell transplantation to generate better-quality biomimetic scaffolds, prevascularize three-dimensional (3D) tissue structures, and engineer the composite interface of diverse facial tissues. In this review, we have discussed the application of different adult stem cells to repair oral and maxillofacial defects in animal models and clinical trials.

Abstract
In this study, human adipose stem cells were isolated from subcutaneous fat in the thigh (htASCs), abdomen (haASCs) and breast (hbASCs). Flow cytometry was used to detect cell surface markers, and an enzyme-linked immunosorbent assay was used to detect paracrine activity. Paracrine gene expression in the three cell types was examined using real-time qPCR, and adipogenic ability was assessed using Oil Red O staining. RNA from third-passage haASCs and hbASCs was sequenced. The results showed that the differentiation potential marker markers CD49d and CD54 were similar across hbASCs from 10 subjects. The hbASCs showed higher colony forming ability and expression of fibroblast growth factor-2, tissue inhibitor of metalloproteinase-1 and stromal cell derived factor-1 than htASCs and haASCs. Stimulating hbASCs with FGF2 promoted adipogenic differentiation, while treating the cells with the PI3K inhibitor LY294002 inhibited differentiation. These results suggest that the PI3K/Akt signaling pathway can promote proliferation and adipogenic differentiation of adipose stem cells, and that activation of this pathway by FGF2 may explain why hbASCs show greater proliferation and adipogenic differentiation than haASCs and htASCs.

Abstract
Morphea and systemic sclerosis are inflammatory, sclerosing disorders. Morphea primarily affects the dermis and subcutaneous fat, while systemic sclerosis typically involves the skin and internal organs. Functional impairment and cosmetic disfigurement are common in both diseases. Treatment options to mitigate disease progression remain limited. Both functional impairment and cosmetic deficits negatively impact quality of life and psychological well-being in this patient population. While the number of cosmetic procedures performed in the United States continues to rise each year, limited data exist regarding best practices for correcting aesthetic deficits caused by autoimmune conditions. There is scarce information to guide safety decisions regarding laser parameters, soft tissue augmentation, treatment intervals, and the concurrent use of immune-modifying or immune-suppressing medications. Given the fears of disease reactivation and exacerbation from postprocedural inflammation along with limited data, it is difficult for clinicians to provide evidence-based cosmetic treatment with realistic expectations with regard to short- and long-term outcomes. In the first article in this continuing medical education series, we attempt to address this practice gap.

Abstract
The craniofacial region is anatomically complex and is of critical functional and cosmetic importance, making reconstruction challenging. The limitations of current surgical options highlight the importance of developing new strategies to restore the form, function, and esthetics of missing or damaged soft tissue and skeletal tissue in the face and cranium. Regenerative medicine (RM) is an expanding field which combines the principles of tissue engineering (TE) and self-healing in the regeneration of cells, tissues, and organs, to restore their impaired function. RM offers many advantages over current treatments as tissue can be engineered for specific defects, using an unlimited supply of bioengineered resources, and does not require immunosuppression. In the craniofacial region, TE and RM are being increasingly used in preclinical and clinical studies to reconstruct bone, cartilage, soft tissue, nerves, and blood vessels. This review outlines the current progress that has been made toward the engineering of these tissues for craniofacial reconstruction and facial esthetics.

Abstract
BACKGROUND Parry-Romberg syndrome (PRS) is a rare condition involving self-limited progressive facial hemiatrophy. AIMS To analyze esthetic results of fat graft used for correcting soft-tissues atrophy in PRS patients, in the aspect of volume restoration and skin rejuvenation, to present our experience in redefining facial contours in PRS and modification of fat graft accusation technique (based on Coleman's technique). PATIENTS/METHODS A prospective evaluation study was designed to analyze esthetic results (contour and skin condition), complications, and subjective satisfaction of eight patients with PRS treated with fat graft. RESULTS All patients underwent two (n = 6) or three (n = 2) procedures in 3 months intervals (the mean 3.7 months). No major postoperative complications were observed. The authors evaluated their esthetic results concerning face contour and symmetry as good (in four patients) and very good (in four patients). Subjective assessment showed high patients' satisfaction with the final result of face contouring (the mean VAS [0-5]-4.75). CONCLUSIONS Our experience shows that fat grafting in patients with PRS is safe and gives satisfactory results in the aspect of volume restoration and skin quality improvement. Modified technique of graft preparation (112 g for 3 minutes) enables to obtain less dense fat graft, which is more appropriate in case of PRS patients with thin atrophic skin.

Abstract
Adipose-derived stem cells (ASCs) are a subset of mesenchymal stem cells (MSCs) that can be obtained easily from adipose tissues and possess many of the same regenerative properties as other MSCs. ASCs easily adhere to plastic culture flasks, expand in vitro, and have the capacity to differentiate into multiple cell lineages, offering the potential to repair, maintain, or enhance various tissues. Since human adipose tissue is ubiquitous and easily obtained in large quantities using a minimally invasive procedure, the use of autologous ASCs is promising for both regenerative medicine and organs damaged by injury and disease, leading to a rapidly increasing field of research. ASCs are effective for the treatment of severe symptoms such as atrophy, fibrosis, retraction, and ulcers induced by radiation therapy. Moreover, ASCs have been shown to be effective for pathological wound healing such as aberrant scar formation. Additionally, ASCs have been shown to be effective in treating severe refractory acute graft-versus-host disease and hematological and immunological disorders such as idiopathic thrombocytopenic purpura and refractory pure red cell aplasia, indicating that ASCs may have immunomodulatory function. Although many experimental procedures have been proposed, standardized harvesting protocols and processing techniques do not yet exist. Therefore, in this review we focus on the current landscape of ASC isolation, identification, location, and differentiation ability, and summarize the recent progress in ASC applications, the latest preclinical and clinical research, and future approaches for the use of ASCs.

Effect of Decantation Time on Viability and Apoptosis in Adipocytes After Liposuction. Aesthetic Plast Surg 2019; 43:228-232. [PMID: 30361982 DOI: 10.1007/s00266-018-1258-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Accepted: 10/10/2018] [Indexed: 01/26/2023]
Abstract
BACKGROUND The effect of decantation time on viability and apoptosis in adipocytes has not been described. The objective of the study was to describe viability and apoptosis in adipocytes up to 2 h after harvesting. METHODS Twenty patients who underwent esthetic liposuction from the abdomen were included. The lipoaspirate was obtained from the infra-umbilical area with the tumescent technique. Liposuction was performed with a 60-ml syringe and a 3-ml cannula. Lipoaspirates were centrifuged at 50 g for 5 min at 0, 60 and 120 min after harvesting. One gram of fat was digested with 0.1% type 1 collagenase and incubated at 37 degrees for 30 min. Adipocytes were counted on 10 random microscopic fields. Apoptosis was determined by TUNEL assay. A fluorescence microscope was used to visualize the staining nuclei and cells. RESULTS Regarding viability, immediately after harvesting, 57.6 ± 18.9% of the cells were viable, whereas 60 min after liposuction the viability decreased to 51.62 ± 8.8% and 120 min after liposuction the percentage of viable cells was 46.8 ± 16.9%. The percentage of apoptotic cells at time 0 was 38.2 ± 8.0%, whereas it was 51.24 ± 8.1% at 60 min and 62.9 ± 16.1% at 120 min after collection. CONCLUSIONS Apoptosis and mortality of adipocytes after liposuction increase directly proportional to the time of decantation. Lipoinjection should be performed as soon as possible after harvesting.

Abstract
Background Non-syndromic craniosynostosis causes craniofacial asymmetry and may persist after cranioplasty. These postoperative asymmetries are primarily depressions. In some cases, patients may be subjected to pranks and harassment by their peers, affecting their psychosocial development. We propose lipoinjection enriched with adipose stem cells (ASCs) to treat the sequelae of craniosynostosis in the fronto-orbital and temporal complex in cranioplasty patients, with the goal of improving the appearance of the upper third of the face. Methods Twelve children (four boys and eight girls) between 4 and 8 years of age (mean age, 6 years) in the postoperative period after treatment for plagiocephaly, brachycephaly, and trigonocephaly were included, with a follow-up period of 1 to 18 months. Fat tissue was obtained from the lower abdomen, and ASCs were isolated using the Yoshimura technique. Lipoinjection was performed using several mini-approaches to ensure adequate distribution. Results Two different scales were used to evaluate the aesthetic outcomes. At 6 months, three plastic surgeons independent of the study classified the results using a Likert scale. The patients’ parents categorized the results using a visual analog scale at 6, 9, and 18 months. R esults were favorable on both scales, as the patients’ facial appearance improved and they reported increased happiness and self-esteem due to their remodeled facial appearance. Conclusions We suggest that lipoinjection enriched with ASCs is a good alternative for correcting asymmetry of the fronto-orbital and temporal contour in patients with sequelae of craniosynostosis. This treatment will help boost patients’ self-esteem starting at an early age.

Abstract
Stem cell-based therapies have been widely used for their abilities to repair and regenerate different types of tissues and organs in cosmetic and plastic surgeries. It involves the clinical application of different types of stem cells. Different stem cells have been reported to be applicable in different areas of cosmetic surgeries like face lipoatrophy, skin rejuvenation, breast enhancement, and body contouring. However, adipose-derived stem cells remain the most widely used by cosmetic surgeons as they have the potential and capability to differentiate into mesenchymal, ectodermal, and endodermal lineages and are easily accessible to harvest. The purpose of this review is to summarize available applications of stem in cosmetic and plastic surgeries.

Abstract
The precise pathoetiology and effective treatment strategies for bisphosphonate-related osteonecrosis of the jaw (BRONJ) remain unknown. Transplantation of noncultured stromal vascular fraction (SVF) cells has been shown to be a useful method for regenerative medicine in place of stem cell therapy. This study investigated the effects of noncultured SVF transplantation on tooth extraction socket healing in mice. Both chemotherapeutic/bisphosphonate combination therapy for 7 weeks and tooth extraction of maxillary first molars at 3 weeks after drug administration were performed using female C57BL/6J mice. Osseous and soft tissue wound healing were validated at 4 weeks postextraction using gross wound healing and histomorphometry. Here, we created a new animal model of high-prevalence ONJ-like lesions that mimic human progression, because human ONJ mainly occurs in female patients taking both chemotherapeutic and bisphosphonate following tooth extraction. Moreover, mice with chemotherapeutic and bisphosphonate combination therapy for 5 weeks received SVF transplantation just after tooth extraction at 3 weeks post-drug administration. Euthanasia was performed at 2 weeks postextraction to assess the transplantation effects on wound healing using gross wound healing, histomorphometry, immunohistomorphometry, quantitative real-time polymerase chain reaction, and microcomputed tomography. We showed that systemic transplantation of noncultured SVF cells ameliorates ONJ-like lesions by improving both osseous and soft tissue healing of tooth extraction sockets. SVF therapy significantly increased blood vessels and the ratio of M2/M1 macrophages. In addition, SVF transplantation reduced the increases in tartrate-resistant acid phosphatase-positive (TRAP+ ) mononuclear cells (MNCs) and nonattached osteoclasts from the bone surface, which were significantly detected in the connective tissue of tooth extraction sockets and bone marrow by chemotherapeutic/bisphosphonate combination therapy. Our findings suggest that transplantation of noncultured SVF cells is a suitable treatment for BRONJ. Abnormal TRAP+ MNCs and nonattached osteoclasts in systemic and local environments may contribute to the development of BRONJ. © 2017 American Society for Bone and Mineral Research.

Abstract
Autologous fat is considered the ideal material for soft-tissue augmentation in plastic and reconstructive surgery. The primary drawback of autologous fat grafting is the high resorption rate. The isolation of mesenchymal stem cells from adipose tissue inevitably led to research focusing on the study of combined transplantation of autologous fat and adipose derived stem cells (ADSCs) and introduced the theory of ‘cell-assisted lipotransfer’. Transplantation of ADSCs is a promising strategy, due to the high proliferative capacity of stem cells, their potential to induce paracrine signalling and ability to differentiate into adipocytes and vascular cells. The current study examined the literature for clinical and experimental studies on cell-assisted lipotransfer to assess the efficacy of this novel technique when compared with traditional fat grafting. A total of 30 studies were included in the present review. The current study demonstrates that cell-assisted lipotransfer has improved efficacy compared with conventional fat grafting. Despite relatively positive outcomes, further investigation is required to establish a consensus in cell-assisted lipotransfer.

Abstract
Perception of the adipose tissue has changed dramatically over the last few decades. Identification of adipose-derived stem cells (ASCs) ultimately transformed paradigm of this tissue from a passive energy depot into a promising stem cell source with properties of self-renewal and multipotential differentiation. As compared to bone marrow-derived stem cells (BMSCs), ASCs are more easily accessible and their isolation yields higher amount of stem cells. Therefore, the ASCs are of high interest for stem cell-based therapies and skin tissue engineering. Currently, freshly isolated stromal vascular fraction (SVF), which may be used directly without any expansion, was also assessed to be highly effective in treating skin radiation injuries, burns, or nonhealing wounds such as diabetic ulcers. In this paper, we review the characteristics of SVF and ASCs and the efficacy of their treatment for skin injuries and disorders.

Abstract
Background Parry-Romberg syndrome (PRS) is a rare craniofacial disease that causes progressive hemifacial atrophy of the soft tissue before spontaneously entering remission. Autologous fat grafting may provide a less invasive alternative, producing aesthetically pleasing results while avoiding the need for traditional microsurgical free flap coverage. Methods A systematic review of the literature was conducted. Inclusion and exclusion criteria were applied. The case report highlights the technique using two-dimensional and three-dimensional photography. Results Our review yielded 31 articles in addition to our case describing 147 cases of lipofilling to correct PRS soft-tissue defects. Patients underwent an average of 2.2 procedures, receiving on average 95 mL of grafted fat. Disease severity was classified into mild (41%), moderate (42%), and severe (17%) in the identified patients. Increasing disease severity correlated with an increasing number of procedures and fat-grafting volumes to achieve adequate aesthetic outcomes (mean, 1.5 and 38 mL; 2.3 and 81 mL; 3.7 and 129 mL, respectively). Reported benefits over flap-based reconstructions included reductions in cost (40%), operative time (50%), donor-site morbidity (52%), and rate of complications (33%). Aesthetic benefits cited included improved skin quality (65%), more natural contours (1%), and more natural facial expressions (10%). Conclusion Fat grafting for correction of PRS-associated soft-tissue defects is receiving heightened acceptance for its ability to restore natural facial contours. While additional fat-grafting procedures may be required with increased disease severity, autologous fat grafting may be a beneficial option as a sole modality to correct PRS-associated soft-tissue atrophy.

Abstract
Facial asymmetry is found in patients with or without cosmetic facial alterations. Some patients have facial asymmetry that manifests underlying skeletal problems, while others have only limited soft-tissue facial asymmetry. Orthognathic surgery brings about a dermatic change, as soft tissue covers underlying bones. Limited soft-tissue asymmetry, meanwhile, is difficult to correct. The treatment modalities for the creation or restoration of an esthetically pleasing appearance were autogenous fat grafts, cartilage graft, and silicon injections. A young female patient had right-side facial asymmetry. The clinical assessment involved visual inspection of the face and palpation to differentiate soft tissue and bone. Although the extra-oral examination found facial asymmetry with skin atrophy, the radiographic findings revealed no mandibular atrophy or deviation. She was diagnosed as localized scleroderma with muscle spasm. In conclusion, facial asymmetry patients with skeletal asymmetry can be esthetically satisfied by orthognathic surgery; however, facial atrophy patients with skin or subdermal tissue contraction need treatment by cosmetic dermatological surgery and orthodontic correction.

Abstract
Cosmetic surgeons have experimented with a variety of substances to improve soft tissue deformities of the face. Autologous fat grafting provides significant advantages over other modalities because it leaves no scar, is easy to use and is well tolerated by most patients. Autologous fat grafting has become one of the most popular techniques in the field of facial plastic surgery. Unfortunately, there are still two major problems affecting survival rate and development: revascularization after transplantion; and cell reservation proliferation and survival. Since Zuk and Yosra developed a technology based on adipose-derived stem cells and cell-assisted lipotrophy, researchers have hoped that this technology would promote the survival and reduce the absorption of grafted fat cells. Autologous adipose-derived stem cells may have great potential in skin repair applications, aged skin rejuvenation and other aging-related skin lesion treatments. Recently, the study of adipose-derived stem cells has gained increased attention. More researchers have started to adopt this technology in the clinical treatment of facial soft tissue deformity. The present article reviews the history of facial soft tissue augmentation and the advent of adipose-derived stem cells in the area of the clinical treatment of facial soft tissue deformity.

Abstract
PURPOSE Correcting facial contour deformities is a challenge, as it demands thoughtful planning on design, composition of flap, and secondary procedures. The thoracodorsal artery perforator (TDAP) flap has become a workhorse flap for various reconstructions. In this report, we present our experience of reconstructing facial contour deformities using the free TDAP adipofascial flap, focusing on its customized design. PATIENTS AND METHOD Sixteen patients underwent correction of a facial contour deformity with free TDAP adipofascial flaps from 2002 to 2012. The causes of defects were Romberg disease (n = 7), oncological defects (n = 5), craniofacial microsomia (n = 3), and trauma (n = 1). The flaps were three-dimensionally designed in a contour map fashion to have different thickness according to the defects by adjusting the height of adipose tissue and varying tissue composition. Customized dimension of flaps having reliable perfusion were harvested with minimized sacrifice of overlying skin. RESULTS Flap size ranged from 6 × 3 cm to 25 × 25 cm. Six flaps were based on two perforators and the other 10 on one. Five flaps were harvested in a chimeric fashion. All flaps survived completely. No donor morbidity developed in any case. Seven patients underwent secondary corrections including fat injection or liposuction. Improved contour and symmetry were achieved in all patients and was confirmed by a photographic evaluation. Mean follow-up period was 37.8months. CONCLUSIONS Our results suggest that the stereoscopic TDAP adipofascial flaps with diligent secondary approaches may be a reliable alternative for aesthetic reconstruction of facial contour deformities. © 2015 Wiley Periodicals, Inc.

Abstract
Craniofacial malformations, have devastating psychosocial implications for many adults and children and causes huge socioeconomic burden. Currently craniofacial defects require soft tissue transfer, bone grafting techniques or difficult procedures such as microvascular free flaps. Such tissues are often limited in quantity, their harvest causes secondary large donor site defects and they lack the capability to fully restore previous form and function. Stem cell technology is being utilised for various tissue and organs of the body and consequently surgeons are eager to transfer these principles for craniofacial surgery. Adipose derived stem cells (ADSCs) are an exciting stem cell source for craniofacial surgeons due to their easy and painless isolation, relatively large abundance and familiarity with the harvesting procedure. ADSCs also have multiple desirable properties including adipogenic, osteogenic and chondrogenic potential, enhancement of angiogenesis and immunodulatory function. Due to these advantageous characteristics, ASDCs have been explored to repair craniofacial bone, soft tissue and cartilage. The desirable characteristics of ADSCs for craniofacial surgical applications will be explained. We report the experimental and clinical studies that have explored the use of ADSCs for bone, cartilage and soft tissue craniofacial defects. We conclude by establishing the key questions that are preventing the clinical application of ADSCs for craniofacial surgery.

Abstract
BACKGROUND Progressive facial hemiatrophy, also called Parry-Romberg syndrome (PRS), is characterized by slowly progressive atrophy of one side of the face and primarily involves the subcutaneous tissue and fat. The restoration of facial contour and symmetry in patients affected by PRS still remains a challenge clinically. Fat graft is a promising treatment but has some shortcomings, such as unpredictability and low rate of graft survival due to partial necrosis. To obviate these disadvantages, fat graft assisted by bone marrow-derived mesenchymal stem cells (BMSCs) was used to treat PRS patients and the outcome was evaluated in comparison with the conventional treatment by autologous fat graft. METHODS Autologous fat graft was harvested by tumescent liposuction. Bone marrow-derived mesenchymal stem cells were then isolated by human Lymphocytes Separation Medium through density gradient centrifugation. Twenty-six patients were treated with autologous fat graft only (group A), whereas 10 other patients were treated with BMSC-assisted fat graft (group B). The Coleman technique was applied in all fat graft injections. RESULTS The follow-up period was 6 to 12 months in this study, In group A, satisfactory outcome judged by symmetrical appearances was obtained with 1 injection in 12 patients, 2 injections in 8 patients, and 3 injections in 4 patients. However, the result of 1 patient was not satisfactory and 1 patient was overcorrected. In group B, 10 patients obtained satisfactory outcomes and almost reached symmetry by 1 injection. No complications (infection, hematoma, or subcutaneous mass) were observed. CONCLUSIONS The results suggest that BMSC-assisted fat graft is effective and safe for soft tissue augmentation and may be superior to conventional lipoinjection. Additional study is necessary to further evaluate the efficacy of this technique.

Abstract
BACKGROUND The success of an autologous fat graft depends in part on its total stromal vascular fraction (SVF) and adipose-derived stem cells (ASCs). However, variations in the yields of ASCs and SVF cells as a result of different harvesting techniques and donor sites are poorly understood. OBJECTIVE To investigate the effects of adipose tissue harvesting technique and donor site on the yield of ASCs and SVF cells. METHODS Subcutaneous fat tissues from the abdomen, flank, or axilla were harvested from patients of various ages by mechanical liposuction, direct surgical excision, or Coleman's technique with or without centrifugation. Cells were isolated and then analyzed with flow cytometry to determine the yields of total SVF cells and ASCs (CD11b-, CD45-, CD34+, CD90+, D7-FIB+). Differences in ASC and total SVF yields were assessed with one-way analysis of variance. Differentiation experiments were performed to confirm the multilineage potential of cultured SVF cells. RESULTS Compared with Coleman's technique without centrifugation, direct excision yielded significantly more ASCs (P < .001) and total SVF cells (P = .007); liposuction yielded significantly fewer ASCs (P < .001) and total SVF cells (P < .05); and Coleman's technique with centrifugation yielded significantly more total SVF cells (P < .005), but not ASCs. The total number of SVF cells in fat harvested from the abdomen was significantly larger than the number in fat harvested from the flank or axilla (P < .05). Cultured SVF cells differentiated to adipocytes, osteocytes, and chondrocytes. CONCLUSIONS Adipose tissue harvested from the abdomen through direct excision or Coleman's technique with centrifugation was found to yield the most SVF cells and ASCs.

Abstract
Aspirated fat contains unnecessary components such as water, oil, and blood cells. For better outcomes, tissue purification and condensation are useful, especially when injection volume to the recipient site is limited. Because aspirated fat is relatively poor in adipose-derived stem/stromal cells (ASCs), ASC condensation seems important for obtaining better regeneration and retention. Reducing tissue volume by removing some adipocytes or supplementation of stromal vascular fraction or ASCs can increase the ASC/adipocyte ratio in the graft. Clinical results of ASC supplementation remain controversial, but ASC condensation seems to lead to expanding applications of fat grafting into revitalization of stem cell-depleted tissue.

Abstract
Adipose-derived stem cells (ADSCs) are a subset of mesenchymal stem cells (MSCs) that possess many of the same regenerative properties as other MSCs. However, the ubiquitous presence of ADSCs and their ease of access in human tissue have led to a burgeoning field of research. The plastic surgeon is uniquely positioned to harness this technology because of the relative frequency in which they perform procedures such as liposuction and autologous fat grafting. This review examines the current landscape of ADSC isolation and identification, summarizes the current applications of ADSCs in the field of plastic surgery, discusses the risks associated with their use, current barriers to universal clinical translatability, and surveys the latest research which may help to overcome these obstacles.

Abstract
Soft tissue augmentation is a process of implanting tissues or materials to treat wrinkles or soft tissue defects in the body. Over the years, various materials have evolved to correct soft tissue defects, including a number of tissues and polymers. Autogenous dermis, autogenous fat, autogenous dermis-fat, allogenic dermis, synthetic implants, and fillers have been widely accepted for soft tissue augmentations. Tissue engineering technology has also been introduced and opened a new venue of opportunities in this field. In particular, a long-lasting filler consisting of hyaluronic acid filler and living human mesenchymal cells called "injectable tissue-engineered soft tissue" has been created and applied clinically, as this strategy has many advantages over conventional methods. Fibroblasts and adipose-derived stromal vascular fraction cells can be clinically used as injectable tissue-engineered soft tissue at present. In this review, information on the soft tissue augmentation method using the injectable tissue-engineered soft tissue is provided.

Abstract
INTRODUCTION Parry-Romberg syndrome (PRS) is a progressive, irreversible disorder characterized by facial lipoatrophy. The patients' physical and psychological well-being is highly affected. The choice of graft for correction of PRS is dictated by numerous factors. This qualitative study aims to present the patients choice of graft for PRS. MATERIALS AND METHODS Reports of experience of patients surgically treated for PRS in the period of 2000-2011 are presented. RESULT A total of 36 patients who had undergone the PRS treatment with fat grafts fulfilled the criteria and were included for the study. Of them 17 (47.2%) were males and 19 (52.8%) were females. For these patients, grafts were obtained from the abdomen in 22 (61.1%) and 14 (38.9%) from the gluteal region. Female PRS patients preferred to have the scar in their gluteal region rather than abdominal region. Similarly, in their immediate postoperative period, most of the patients were apprehensive about the over correction but where satisfied with the long term results of the surgery. DISCUSSION Female PRS patients whose donor site was gluteal region had better perception than those with abdominal grafting. Similarly in immediate postoperative period, they felt that their outcome was not satisfactory. The morphology and metabolic activity of gluteal adipocytes are unique and probably accounts for the better survival rates.

Abstract
Adipose stem cells (ASCs) are a type of adult stem cells that share common characteristics with typical mesenchymal stem cells. In the last decade, ASCs have been shown to be a useful cell resource for tissue regeneration. The major role of regenerative medicine in this century is based on cell therapy in which ASCs hold a key position. Active research on this new type of adult stem cell has been ongoing and these cells now have several clinical applications, including fat grafting, overcoming wound healing difficulties, recovery from local tissue ischemia, and scar remodeling. The application of cultured cells will increase the efficiency of cell therapy. However, the use of cultured stem cells is strictly controlled by government regulation to ensure patient safety. Government regulation is a factor that can limit more versatile clinical application of ASCs. In this review, current clinical applications of ASCs in plastic surgery are introduced. Future stem cell applications in clinical field including culturing and banking of ASCs are also discussed in this review.

Abstract
In covering wounds, efforts should include utilization of the safest and least invasive methods with goals of achieving optimal functional and cosmetic outcome. The recent development of advanced wound healing technology has triggered the use of cells to improve wound healing conditions. The purpose of this review is to provide information on clinically available cell-based treatment options for healing of acute and chronic wounds. Compared with a variety of conventional methods, such as skin grafts and local flaps, the cell therapy technique is simple, less time-consuming, and reduces the surgical burden for patients in the repair of acute wounds. Cell therapy has also been developed for chronic wound healing. By transplanting cells with an excellent wound healing capacity profile to chronic wounds, in which wound healing cannot be achieved successfully, attempts are made to convert the wound bed into the environment where maximum wound healing can be achieved. Fibroblasts, keratinocytes, adipose-derived stromal vascular fraction cells, bone marrow stem cells, and platelets have been used for wound healing in clinical practice. Some formulations are commercially available. To establish the cell therapy as a standard treatment, however, further research is needed.

Abstract
BACKGROUND Stem cells are a unique cell population characterized by self-renewal and cellular differentiation capabilities. These characteristics, among other traits, make them an attractive option for regenerative treatments of tissues defects and for aesthetic procedures in plastic surgery. As research regarding the isolation, culture and behavior of stem cells has progressed, stem cells, particularly adult stem cells, have shown promising results in both translational and clinical applications. METHODS The purpose of this review is to evaluate the applications of stem cells in the plastic surgery literature, with particular focus on the advances and limitations of current stem cell therapies. Different key areas amenable to stem cell therapy are addressed in the literature review; these include regeneration of soft tissue, bone, cartilage, and peripheral nerves, as well as wound healing and skin aging. RESULTS The reviewed studies demonstrate promising results, with favorable outcomes and minimal complications in the cited cases. In particular, adipose tissue derived stem cell (ADSC) transplants appear to provide effective treatment options for bony and soft tissue defects, and non-healing wounds. ADSCs have also been shown to be useful in aesthetic surgery. CONCLUSIONS Further studies involving both the basic and clinical science aspects of stem cell therapies are warranted. In particular, the mechanism of action of stem cells, their interactions with the surrounding microenvironment and their long-term fate require further elucidation. Larger randomized trials are also necessary to demonstrate the continued safety of transplanted stem cells as well as the efficacy of cellular therapies in comparison to the current standards of care.

Abstract
Our objective was to explore the mechanism of cell-assisted adipose transplantation by using freshly isolated human stromal vascular fraction (SVF) cells and to observe the dynamic changes of the graft after transplantation. The SVF was isolated from human liposuction aspirates, and 0.5 ml adipose tissue was mixed with 1 × 10(6) SVF cells or culture medium then injected to nude mice subcutaneously. At 1, 4, 7, 14, 30, 60, and 90 days after transplantation, samples were harvested for 1) general observation and retention rate; 2) whole-mount stain; 3) H&E stain; 4) immunohistochemical staining for S100, CD68, and CD34; 5) ELISA for VEGF and bFGF; 6) peroxisome proliferator-activated receptor-γ (PPARγ) fluorescence in situ hybridization. The retention rate in the experiment group was markedly higher than that in the control group. Whole-mount stain shows most of the cells in the center of the graft could not survive the ischemia until day 14. Histology showed new vessels on the surface of the graft at 3 days. However, in the control group, fewer newly formed vessels were detected until day 7. In the late stage of transplantation, gradual fibrosis was found in the graft, and the tissue was divided into a grid-like structure. A large number of round neonatal adipocytes with big nuclei in the center were found surrounding the new vessels, which were S100 and CD34 positive and CD68 negative. In the late stage of transplantation, most of the neonatal adipocytes were human PPARγ positive. Moreover, the SVF group showed a higher level of VEGF and bFGF. SVF assisting adipose transplantation could increase the retention rate of the graft through promoting adipose tissue regeneration via secretion of growth factors, promotion of angiogenesis, and increasing the density of mesenchymal stem cells.
